AI welcomes the "big test" of energy consumption

  1.05 trillion kWh (kW h)!

  This is the prediction made by the International Energy Agency (hereinafter referred to as "IEA") in the report "Power 2024" recently, on the highest total power consumption of global data centers in 2026. 1 kWh is 1 kWh, "more than 1 trillion kWh". According to the report’s estimation, this amount of electricity is about the entire annual electricity consumption of Japan.

  Computing infrastructure such as data center and intelligent computing center is the data center and computing carrier of artificial intelligence (AI). With the rapid development of AI, especially the generative artificial intelligence (AIGC) and large model technology, the demand for computing power has surged, and the energy consumption of AI has attracted more and more attention. At many international conferences held recently, some technology giants have expressed their concerns about the energy consumption caused by the development of AI.

  How to solve the energy consumption problem while improving intellectual efficiency is a "big test" for the AI industry.

  The energy consumption of AI in the reasoning stage can not be ignored.

  When discussing the energy consumption of AI, it is inevitable to talk about the AI big language model (hereinafter referred to as the "big model").

  "Generative artificial intelligence is the focus of current AI technology development." Wang Peng, a senior expert of Tencent Research Institute, said in an interview with the reporter of Zhongqing Daily and Zhongqing.com.. He said that at present, the foundation of generative artificial intelligence technology is a large model marked by the stacking of data and computing power, and its training and application need a lot of computing power support. "Behind computing power is the huge power demand brought by the power consumption of computing infrastructure."

  Zhang Yunquan, a member of Chinese People’s Political Consultative Conference and a researcher at the Institute of Computing Technology, Chinese Academy of Sciences, pointed out that the larger the parameters and data scale of a large model, the better its intelligence effect. In the large model, "Scaling Laws" means that when the parameters and data are large enough, the intelligent performance of the large model will jump, that is, "intelligent emergence". "At present, we haven’t seen the upper limit of’ smart emergence’."

  "Generally speaking, the larger the parameters, the greater the computational power consumption of the large model, and the more power it consumes." Wang Peng said that because the upper limit has not been reached, artificial intelligence companies represented by OpenAI, driven by "Scaling Laws", continue to increase the parameters and data scale of large models in order to achieve the goal of General Artificial Intelligence (AGI), resulting in a huge increase in computing power demand and power demand in the short term.

  "Because GPT-3 has 175 billion parameters and 1024 NVIDIA A100 chips are used for training, it is called’ thousand calories and thousands of ginseng’ in the industry." Tian Feng, president of Shangtang Science and Technology Intelligent Industry Research Institute, said that at present, GPT-4, GPT-5 and other large models have all reached the scale of "Wanka Wancan", and the chips used in training models have also been updated from NVIDIA A100 to NVIDIA H100 and B200. "The surge in parameters will lead to a significant increase in energy consumption".

  In addition to model training, the energy consumption of AI in the reasoning stage can not be ignored. "Reasoning is the process that the large model responds to the user’s demand", Zhang Yunquan introduced that the power consumption of the large model responding to the user’s demand at a time is not large, "but with the increase of the user scale, the power consumption will continue to accumulate and increase."

  Recently, a news from the United States that "if 100,000 NVIDIA H00 chips are deployed in the same area for model training, the power grid will collapse" has aroused social concern.

  In an interview with reporters, many experts said that the reason why AI led to the collapse of the power grid is that the training of large models is a phased work, and the computing power used should be concentrated in a data center. Training large models in a limited time and space will bring a very large power load to the local power grid.

  "Sudden huge load disturbance in a stable power grid system will have an impact on the stability and security of the power grid." Zhang Yunquan pointed out that with the further increase of large model parameters and data scale, the energy consumption problem of AI will become more and more prominent, especially for countries and regions with tight power supply. "In the long run, the energy consumption of the AI ? ? reasoning process will become larger and larger; In the short term, the energy consumption of large model training is the largest increase in AI energy consumption. "

  In Wang Peng’s view, compared with household electricity consumption, AI’s power consumption is very large, but its proportion in the total social electricity consumption is still very small, "far from reaching the order of magnitude of manufacturing electricity consumption".

  Solution: technological innovation and new energy

  According to the prediction of the American organization Uptime Institute, by 2025, the proportion of AI-related businesses in the global data center electricity consumption will increase from 2% to 10%; By 2030, the annual power consumption of intelligent computing will account for 5% of the total global power generation.

  "Solving the energy consumption problem is an important prerequisite for the development of AI technology." Tian Feng told reporters that although the current energy consumption of AI will not cause a large-scale "power shortage", with the large-scale application of AI, there may be a "power shortage" of AI in the future, and it is necessary to find a suitable solution so that the limited electric energy can accommodate a larger scale of computing power.

  Through research and practice, people’s understanding of AI has gradually increased, and a series of solutions have followed. From the demand point of view, optimizing large model architecture, improving chip efficiency and computing power efficiency are considered to be effective ways to reduce AI energy consumption.

  Zhang Yunquan said that, first of all, a special chip for AI model training can be designed, and its efficiency is more than 10 times higher than that of GPU (graphics processor, now commonly used in AI computing); Secondly, the parameters of AI model can be optimized. Many small models have only a few billion parameters, but they have achieved the same effect as large models. In addition, by optimizing and compressing the reasoning process, a special reasoning chip can be designed to further reduce the energy consumption in the AI reasoning stage.

  "The big model becomes smaller, and the effect of reducing energy consumption is the best at present." Zhang Yunquan takes Phi-3, a self-developed small-size AI model released by Microsoft at the end of April, as an example. It is understood that there are currently three versions of Phi-3 model, among which Phi-3 mini is a language model with 3.8 billion parameters, which can be deployed on mobile phones. According to the experimental and test results, its performance can be comparable to that of GPT-3.5 and other large models.

  In terms of energy supply, resorting to diversified new energy supply and relying on the state for macro-control and planning will help solve the energy consumption problem of AI. Guo Tao, an angel investor and a senior artificial intelligence expert, told reporters that at present, new energy sources, including renewable energy such as solar energy, wind energy and hydropower, are gradually becoming the best energy choice for data centers. "If there is not enough renewable energy to meet the growth of AI energy consumption, it may lead to increased dependence on fossil fuels, which will have a negative impact on the environment. In addition, the data center can also optimize energy efficiency through intelligent algorithms and realize the coordinated development of AI and power grid. "

  Many artificial intelligence companies have begun to pay attention to new energy sources. In 2021, Sam altman, CEO of OpenAI, invested $375 million in Helion Energy, a nuclear fusion startup; In March 2024, Amazon Cloud Services (AWS) acquired a data center park in Pennsylvania, USA. It is understood that the park obtains electricity from neighboring nuclear power plants.

  "Solving the problem of AI energy consumption involves the coordination and cooperation of multiple systems such as computing power and electricity." Wang Peng pointed out that on the one hand, it is necessary to reduce energy consumption from AI itself, including optimizing algorithms, reducing model parameters, and improving computing performance; On the other hand, the entire energy system should also actively respond to the energy consumption demand of AI.

  Integrated consideration of "source, network and storage"

  New energy will become a "key" to solve the problem of AI energy consumption, which coincides with the "East Counting and West Computing" project proposed by China.

  According to the data of the National Energy Administration, in 2023, China’s renewable energy installed capacity was 305 million kilowatts, accounting for 82.7% of the country’s new power generation installed capacity, accounting for half of the world’s new installed capacity; The national renewable energy power generation is nearly 3 trillion kWh, which is close to 1/3 of the electricity consumption of the whole society. At present, China has built the world’s largest power supply system and clean power generation system, among which Qinghai, Inner Mongolia, Ningxia and other northwest regions are "rich mines" of clean energy.

  In 2021, China proposed to implement the project of "calculating from the east to the west" to guide data centers to gather in resource-rich areas in the west, promote local data centers to be low-carbon, green and sustainable, and meet the computing power demand in the east. In February 2022, eight cities including Inner Mongolia, Guizhou and Gansu started to build national computing hub nodes, and 10 national data center clusters were written into the overall "planning" of the project, and the "East Counting and West Computing" project was fully launched.

  "In the era of big model, the project of’ East Counting and West Computing’ will play an important macro-control role in the national power demand and computing power demand." Zhang Yunquan predicted that in the future, more and more large-scale computing centers or intelligent computing centers will be located in the western region of China, and "training from the east to the west" (that is, the AI model in the eastern region will be trained in the western region-reporter’s note) will become a typical scenario for the coordinated development of AI and new energy. However, he stressed that energy storage is a problem that needs to be solved to promote new energy to better empower the development of AI.

  "The construction of large-scale energy storage determines whether new energy can better meet the demand for computing power." Tian Feng also agreed with Zhang Yunquan. Tian Feng pointed out that new energy sources, including photoelectricity and wind power, have the characteristics of intermittent power generation, so it is necessary to rely on energy storage system to store the generated electricity in time, so as to ensure the balance between supply and demand of the power grid.

  According to the latest data from the National Energy Administration, by the end of the first quarter of 2024, the cumulative installed capacity of new energy storage projects that have been completed and put into operation in China has reached 35.3 million kilowatts, an increase of more than 210% year-on-year, of which over 50% are energy storage power stations with a capacity of over 100,000 kilowatts, showing a centralized and large-scale development trend.

  In the construction of energy storage, Wang Peng emphasized the distributed energy storage capacity of new energy vehicles. "With the continuous improvement of battery charging and discharging times and service life, hundreds of millions of trams use the peak-valley electricity price difference to store energy and return it to the power supply network in reverse, which can basically realize zero-cost car use and even profit, and also solve the peak shaving problem of the power grid."

  In addition, Wang Peng also thinks that it is necessary to rethink the distributed linkage and micro-layout coordination of "data network" and "power network". He pointed out that in order to meet the rapidly growing demand for artificial intelligence reasoning computing power in the short term, in addition to laying out large computing centers in areas rich in renewable energy in the west, it is necessary to realize "east counting and west computing"; It is also necessary to consider actively deploying distributed renewable energy sources near the data center and computing center on the east demand side, such as distributed BIPV (Photovoltaic Building Integration) combined with urban and rural buildings and agricultural facilities, and integration of light storage and flexibility. "Moreover, it is necessary to consider the integration of’ source network and storage’, and realize the local peak-valley balance through the microgrid as much as possible to reduce the abandonment of wind and light."

  "This requires the cooperation of electricity price policy, infrastructure construction, policy support and user behavior." In Wang Peng’s view, the high coupling of the whole computing network, transmission network, distributed energy network and vehicle (charging) network may be the key to solve the future AI energy consumption problem in China.

  "Considering the general ledger of input and output, AI actually further improves the production efficiency of society and reduces energy consumption." Tian Feng believes that AI, as a new quality productivity, is empowering economic and social development. Today’s AI big model has become an important basic scientific research facility, and the investment in its training will eventually bring dividends of new quality productivity to the whole society.

  At present, in the training cost of AI big model, the proportion of energy consumption cost has exceeded half. Tian Feng said that from the perspective of basic scientific research, we should continue to increase investment in AI technology. "Now is the time to catch up, and we should not tie our hands and feet.". Specific to the energy consumption of AI, he suggested that a large model can be trained with certain energy support policies.

A series of commentator’s articles in the Political Research Office of the Provincial Party Committee: the word "efficiency" is the key.

Editor’s note:Since the provincial party committee deployed and implemented the action of improving efficiency, efficiency and efficiency, the party organizations at all levels in the province and the cadres in party member have become more and more interested in "efficiency", showing their spirit, starting their own businesses, and emphasizing efficiency and seeking efficiency. In April, the Political Research Office of the Provincial Party Committee published a comprehensive interpretation article "Improving Efficiency, Improving Effectiveness and Increasing Benefit" and a series of commentator articles "Grasping Work to Improve Efficiency, Improving Service to Improve Efficiency, and Promoting Development to Increase Benefit" in this newspaper. From now on, Fujian Daily will continue to publish a series of commentator articles of the Political Research Office of the Provincial Party Committee, such as "Effective Word is the Key", "Steady Word is the Head" and "Doing in Practice" for readers.

A series of commentator's articles in the Political Research Office of the Provincial Party Committee: the word "efficiency" is the key.

Everything may not be successful, but it must be effective. To implement the action requirements of improving efficiency, efficiency and efficiency deployed and implemented by the provincial party committee this year, we should adhere to the word "efficiency" to grasp the work and promote development, establish a clear orientation of emphasizing efficiency, seeking efficiency and showing effectiveness in the whole province, and guide party member cadres to do effective things and use effective work to ensure the delivery of an efficient answer sheet with high quality and development. In the first half of the year, the whole province made great efforts to reduce the impact of the epidemic. The GDP of the whole province increased by 4.6% year-on-year, which was 2.1 percentage points higher than that of the whole country. In the second half of the year, the task is even more arduous. We must spur the horse and strive to recover the losses caused by the epidemic, ensuring that the third quarter is better than the second quarter and the second half is better than the first half.

Quick effect, good effect and obvious long-term effect are coordinated. This is the core meaning of the word "efficiency" to grasp the work and promote development. Quick results are to implement the work deployment in depth and detail as quickly as possible, so as to achieve efficiency according to attitude and responsibility. This is particularly important in epidemic prevention and control. Our province has formed a valuable experience of "fast, accurate and strict" in winning the epidemic annihilation war, and the word "fast" is the first thing to do, so as to beat the virus quickly. Once the epidemic situation is discovered in the province, the provincial party committee will organize relevant regions to seize the opportunity and take decisive actions to control the epidemic situation in a short time and create a good premise and foundation for economic and social development. Seeing good results means that our work should not only pursue speed and efficiency, but also pursue quality and efficiency. In dealing with the epidemic situation, the provincial party committee always pays attention to ensuring smooth and smooth communication, and strives to ensure that key enterprises do not stop working and stop production during the epidemic period. At the same time, according to the changes in the prevention and control situation, they should make scientific judgments and act with a camera, and promptly organize the resumption of work and production, without simplification, across the board, overweight at different levels, and disturbing the people as little as possible, with a view to restoring normal production and living order as soon as possible and minimizing the impact of the epidemic on economic and social development. In view of the fact that the downward pressure on the province’s economy increased in the second quarter, the provincial party Committee issued 48 packages of policies and measures in eight aspects at the first time with extraordinary efforts, so as to meet the requirements of the central government, learn from the measures taken outside the province, and respond effectively to the needs of market entities; At the same time, deepen the system of "four basic units" and carry out the action of "ten thousand cadres entering enterprises" to "solve the thirst near" and "discharge the worries far away" for market players. Just because we can persist in and apply the dialectics of "fast" and "good",Only in the first half of the year can our province achieve the double victory of epidemic prevention and control and economic and social development. Significantly long-term effect means that our work should not only be fast and good at present, but also persist in making efforts for a long time, so as to lay a foundation and benefit the long term. During his work in Fujian, General Secretary of the Supreme Leader formulated and implemented Xiamen’s 15-year development plan, Fuzhou’s "3820" strategic project with strategic thinking and forward-looking vision, and innovatively promoted the construction of ecological province and digital Fujian, which fully reflected the spiritual realm of "I don’t have to be successful" and the responsibility of "I must be successful". This enlightens us that only by linking history, reality and future development, coordinating short-term, medium-term and long-term goals, focusing on long-term planning, establishing rules and regulations, and implementing them one after another can we achieve more long-term and sustainable development.

In short, it is important to have "efficiency" in a place to promote development. This "effect" is concrete, not abstract, and should be embodied in reality. For example, it is necessary to continuously expand GDP. Development is the foundation and key to solve all problems, and growth is the premise and support of development. To develop, there must be GDP growth. We can’t pursue GDP unilaterally, but it’s not that we don’t want GDP. If GDP does not increase or the growth rate is too low, high-quality development and improvement of people’s livelihood will be empty talk. Another example is to continuously increase the income of residents. This is the key to creating a high-quality life and achieving common prosperity, and it is also an important aspect of high-quality development. Only in this way can we lay a solid foundation for enhancing people’s sense of well-being and security. Another example is to continuously increase fiscal revenue. The development of a place should not only enrich the people, but also strengthen financial resources. Only in this way can we provide a strong guarantee for construction and benefit the people’s livelihood. Of course, this "effect" is also reflected in employment, prices and social stability.

The combination of problem orientation, goal orientation and result orientation. This is the practical path of focusing on work and promoting development. Problems, goals and results are three aspects of dialectical unity and complementary development of things. In order to improve the quality and efficiency of economic and social development, it is necessary to release the problem-oriented "boosting force", enhance the goal-oriented "traction force" and form the result-oriented "driving force". "Problem is the slogan of the times", adhering to the problem orientation means grasping the main aspects of major contradictions and contradictions, and making efforts to fill shortcomings, strong and weak items and plug loopholes. Not long ago, provincial leaders led teams to all counties (cities, districts) in the province to carry out work inspections and "two stabilities, one insurance and one prevention" supervision activities, focusing on problems, taking pulse consultations and supervising and helping, and going deep into the front line to solve problems and promote development. This will certainly strongly promote leading cadres at all levels to grasp the work, promote development, aim at the problem, chase the problem, get through the blocking points, solve the difficulties, eliminate the pain points, and let the actual results follow. "Shooting should aim at the bull’s-eye" and adhere to the goal orientation, that is, insisting that the goal is not relaxed and moving towards the goal step by step. The 11th Provincial Party Congress proposed that by 2035, our province will basically achieve all-round and high-quality development. To achieve the set goals, we need to rely on hard work and hard work. At present, it is necessary to closely follow the annual objectives and tasks of economic and social development, with the determination that "eagles have to stop attacking things", not to be hindered by difficulties, not to find excuses, to pay close attention to implementation and to win success. After hard work, the province’s economic operation remained in a reasonable range in the first half of the year, and in the second half of the year, we should continue to introduce more practical measures and do everything possible to stabilize the basic economic disk.Constantly enhance economic innovation and core competitiveness. "Looking forward is the goal, looking back is the result", and adhering to the result orientation means speaking with actual results and talking about heroes with actual achievements. The final result depends on the results of each stage of work, so we must ensure that each stage of work is carried out effectively and lay the foundation for the next stage of work. This requires us to pay close attention to every week, month and season, work hard, steadily and steadily, push forward, change "promising" into "effective" and change "in progress" into "completed", which is not only "said and done" but also "done and done".

Political effect, economic effect and social effect are unified. This is the value orientation of focusing on work and promoting development. Fast-paced improvement of efficiency, excellent service and efficiency, and improvement of efficiency through practical work contain the unremitting pursuit of "efficiency", and it is also the integration and coordination of political, economic and social effects. Our province is an important breeding ground and practice place for the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era. The most concentrated expression of political effect is to give full play to the unique advantages, thoroughly implement the spirit of the important instructions of the important speech of the Supreme Leader General Secretary on Fujian’s work, turn the deep love for the Supreme Leader General Secretary into a powerful driving force for the entrepreneurial work of the officials, and support the "two establishment" and achieve the "two maintenance" with practical results. Economic effect reflects the relationship between economic activities and labor consumption, and high-quality development must rely on the growth of total factor productivity. The key is to lead the construction of innovative provinces with talents, make the digital economy, marine economy, green economy and cultural tourism economy bigger and stronger, fill the shortcomings such as weak scientific and technological innovation ability, poor industrial structure and low income of residents, accelerate the construction of a modern economic system, continuously expand the economic aggregate and scale, and continuously improve the quality and efficiency of economic development. Social effects are expressed in the form of social reactions and repercussions. Whether the work is effective or not, the satisfaction of the masses is the fundamental evaluation criterion. This requires the establishment and improvement of the evaluation system oriented to the satisfaction of the masses, avoiding formalism and bureaucracy, solving the most concerned, direct and realistic interests of the masses, and achieving "whether the effect is good or not, the masses have the final say".

Xiang Tao, the trendsetter, made his head stand, seeking new articles and seeking from the effect. Only by adhering to the spirit of "doing it right away, getting down to work" and the sense of responsibility of "always worrying about it", and effectively coordinating epidemic prevention and control and economic and social development, can we accumulate momentum, win the opportunity, and take a good road to high-quality development in the new era.

60,000 physical examinations found that these health problems were high and "different between men and women".

  Changsha Evening News All-Media Reporter Zhu Yanhuang Correspondent Song Yani

  Recently, the physical examination center of Changsha Hospital of Traditional Chinese Medicine (Changsha No.8 Hospital) analyzed the personal health status of 60,000 people who underwent physical examination in this center this year.

  Since January this year, there have been about 35,000 men and 25,000 women in the hospital. Statistics show that among men, overweight and obesity, hyperlipidemia, fatty liver and calculus are the top three common health problems, accounting for about 54%, 46% and 25% of the tested men respectively. Among women, the top three health problems are hyperplasia of mammary glands, abnormal thyroid gland, abnormal TCT and HPV, accounting for about 85%, 40% and 25% of the examined women respectively. Chen Lianchun, director of the physical examination center of the hospital, reminded that the ratio of common high-risk health problems has increased compared with last year. It is suggested that the medical examination package should be personalized and targeted, and the health management after the examination should be strengthened.

  The first problem of male health: overweight and obesity

  Mr. Wang, a case freelancer, loves fried food and carbonated drinks. He often plays cards and sits for four or five hours. At the time of physical examination, he was 1.65 meters tall and weighed 90 kilograms, which was close to severe obesity.

  Obesity directed by doctors is mainly caused by unreasonable diet and insufficient physical exercise. The Report on Nutrition and Chronic Diseases of Residents in China (2020) shows that the overweight and obesity rate of adult residents in China exceeds 50%. Body mass index (BMI) is the most commonly used measure of overweight and obesity in adults. "Overweight" means that the BMI is equal to or greater than 24, and "obesity" is equal to or greater than 28. 20% of people who weigh more than the standard weight are mildly obese, over 30% to 50% are moderately obese and over 50% are severely obese.

  Chen Lianchun said that overweight or obesity will cause different degrees of harm to the cardiovascular, digestive, skeletal, endocrine and other systems of the human body. It is necessary to carry out scientific weight management and treatment to reduce weight and fat. In addition, it can be differentiated according to the different constitutions of patients and given special Chinese medicine treatment to help reduce fat.

  Male health problems ranked second: hyperlipidemia and fatty liver.

  Case Mr. Li has been diagnosed with hyperlipidemia for more than 5 years. Because he was afraid of trouble, he did not go to the hospital for treatment. There are hyperlipidemia and fatty liver in the physical examination data every year, and the value of blood lipid increases year by year, and fatty liver also changes from mild to moderate.

  The doctor instructed that "hyperlipidemia and fatty liver are caused by excessive fat deposition in blood vessels or liver cells." Chen Lianchun suggested that this kind of patients should first adjust their diet structure, and need a low-salt, low-fat, high-vitamin and high-quality protein diet every day, and do not consume foods that are too high in fat and calories. If the data does not decrease but increases after a period of diet and exercise conditioning, you need to use lipid-lowering drugs under the guidance of a doctor.

  Male health problems ranked third: stones.

  Case Peng is a truck driver. Because it is inconvenient to go to the toilet in the middle of his work relationship, he deliberately reduced drinking water. Young, he had an operation because of kidney calculi’s hydronephrosis. To his distress, a small stone about 2×3 mm grew on the side of his kidney this year.

  Kidney calculi, ureteral calculi, bladder calculi, urethral calculi, etc., which are commonly found in men. Dong Ying, deputy chief physician of the physical examination center, said that the onset may be related to many factors such as abnormal metabolism and unhealthy lifestyle, such as dislike of drinking water and lack of exercise.

  For smaller stones, patients should strengthen drinking water and exercise. According to their own habits and weight, they can drink 2000 to 3000 ml of warm water every day, and after drinking, they can cooperate with exercise, such as skipping rope or jumping with their feet for more than 5 minutes every day. Larger stones are easy to get stuck in ureteral stricture or urethral obstruction or effusion during activities, which may cause waist swelling and discomfort, perineal pain, hematuria, etc., so surgery is needed to remove the stones.

  The first problem of women’s health: mammary gland hyperplasia

  Case Ms. Gu is a teacher. She usually works hard, often stays up late, and likes spicy food. This year’s physical examination report suggests: bilateral breast hyperplasia, right breast cystic nodules.

  The doctor’s guidance of mammary gland hyperplasia refers to the benign hyperplasia of mammary gland tissue, which occurs in young and middle-aged women. It is one of the most common diseases of women. Its clinical manifestations are proliferative nodules or lumps, periodic breast pain, which can radiate to armpits, chest and shoulders, mainly related to endocrine disorders, irregular living habits, bad mood and other factors.

  Traditional Chinese medicine believes that mammary gland hyperplasia is related to stagnation of liver qi and deficiency of phlegm and blood coagulation, and the disease is located in liver, spleen and kidney. After the diagnosis of hyperplasia of mammary glands, we should pay attention to changing the unhealthy lifestyle, staying up late less, eating less spicy food, keeping a good mood, and having regular breast ultrasound or mammography reexamination. If there is a hint of malignant lesions, surgical treatment should be carried out in time.

  Women’s health problems ranked second: thyroid abnormalities.

  During the physical examination, Ms. Gao found that the thyroid gland was slightly enlarged. Further thyroid function examination and color Doppler ultrasound examination revealed hypothyroidism with Hashimoto’s thyroiditis. She said that she had gained weight recently and was accompanied by weakness.

  The thyroid diseases instructed by doctors include hyperthyroidism, hypothyroidism, thyroiditis, thyroid nodules, goiter, thyroid tumor, etc., which are related to factors such as lack or excess of iodine, changes in living habits, stress, taking hormones and diuretics. Thyroid malignant tumor is the most common malignant tumor in endocrine system, with the fastest growing incidence, with more women than men.

  Dong Ying said that thyroid cancer often manifests as painless neck lumps or nodules, and general surgery is the most important treatment. If thyroid color Doppler ultrasound or thyroid dysfunction is found, it is recommended to see a doctor in endocrinology or thyroid surgery, and check the medication or surgery regularly according to the doctor’s advice. You can’t stop taking the drug on your own or don’t check it after stopping it.

  Women’s health problems ranked third: abnormal TCT and HPV.

  Case Ms. Huang usually has no obvious gynecological discomfort. In the past, there was no obvious abnormality in routine gynecological examination and TCT (cancer screening) examination. This year, she added HPV (Human Papillomavirus) examination, and the results of TCT report showed: atypical epithelial cell hyperplasia, HPV virus classification: high-risk type (+), low-risk type (+).

  Doctor Dong Ying said that TCT mainly checks whether there are cytological abnormalities in cervical tissues, such as low-grade squamous intraepithelial lesions and high-grade squamous intraepithelial lesions, while HPV tests cervical secretions for HPV-DNA to determine whether there is HPV infection.

  HPV infection is mostly transient, and if HPV infection persists, the risk of cervical cancer will increase accordingly. The combination of TCT and HPV can improve the diagnosis rate of cervical cancer. It is suggested that women of childbearing age should be screened regularly. If there is long-term HPV infection or TCT examination shows a tendency of malignant transformation, further cervical biopsy is needed to make a definite diagnosis.

The core technology of shield tunneling in China is becoming more and more mature, and tunnel construction has entered the "intelligent era"

The "Hongpu" went offline. Photo courtesy of respondents

Recently, new progress has been made in the 11th bid project of Shanghai Airport tie line. The total mileage of shield tunneling has exceeded 3,000 meters. The super-large diameter pneumatic mud-water balance shield machine "Hongpu" independently designed and developed by CCCC has played an important role in this project.

According to reports, the cutter head of Hongpu is 14.04 meters in diameter, 114 meters in total length and 3,174 tons in total weight. It not only applies advanced technologies such as optical fiber wear detection of cutters and unique ultra-long distance tunneling without changing cutters (high confined water silt stratum can achieve continuous tunneling over 7,000 meters without changing cutters), but also is equipped with intelligent systems such as intelligent monitoring and automatic guidance, creating a new height of similar tunnel construction equipment at home and abroad, and the localization rate reaches.

At the same time, the intelligent remote safety monitoring and management system can record the tunneling data of the shield machine in real time, realize the independent management of the risk boundary, send out the warning in time and provide the solution plan to ensure the whole life cycle management of the shield machine. The automatic guiding system is equipped with smart eyes for the shield machine, which can more accurately judge the heading direction and working posture of the shield machine, and control the heading accuracy of the shield machine within ±2mm, which not only ensures the heading construction quality, but also greatly improves the intelligent level of the heading operation. Up to now, the "Hongpu" has excavated more than 3,000 meters of tunnels, creating a national record of 650 meters per month for super-large diameter shield machines and a new world record of 16 rings and 32 meters per day.

"In the deep underground of the city, there is no need for engineers to make manual decisions and operations. Shield machines weighing thousands of tons and more than 100 meters can automatically dig tunnels such as subways, highways and high-speed railways through artificial intelligence." This is the future development trend of shield machines and the biggest dream of shield machines. In order to realize this dream, the shield machine must have the necessary core technology to realize autonomous "cruise" tunneling and intelligent segment assembly under unmanned driving. By then, technicians and operators can watch the shield machine realize autonomous tunneling under the control of artificial intelligence through the monitoring screen only outside the tunnel.

"The core technology of unmanned tunneling of shield machine in China Communications Day has become increasingly mature.
