Five years ago, in the summer of a graduation season, Tian Hongqi, the first female principal of Central South University, delivered a speech at more than 13,000 graduates. She said, "Being a man, you have to carry things."

If you look back at Tian Hongqi carefully -the past experience of the Chinese Academy of Engineering, the first female principal of Central South University, and the second prize of the national technology invention, you will find that this graduation gift highly condenses her life experience Essence

From the Changsha Railway Academy, to occupying a place in the field of rail transit, and then to the helm of the top university institutions in Hunan, Tian Hongqi's fate and the modern railway modernization of the Republic of the Republic have rely on "carrying things" to today. She pioneered the "control of wind" of the high -speed railway, and allowed the Qinghai -Tibet Railway to "move forward against the wind" on the plateau and became the "iron lady" that had to be remembered when she took a train to Lhasa. " As a female technology worker, her female identity and grades are like her name, becoming a red flag in the hearts of the next generation of female technology workers.

01

The glorious years of growing up with "Iron Boss"

In March 1978, the 19 -year -old Henan girl Tian Hongqi came to Changsha, Hunan. In a place called "mud" in the southern suburbs -Changsha Railway Academy, she started her struggle for more than 40 years.

In the future, the Changsha Railway Academy will become an important part of the Central South University of Hunan University. At the railway vehicle specialty of the railway academy, Tian Hongqi began the starting point of scientific research.

With her, there are many young talents from all directions. These young people do not know that their mission has gradually become clear under the pace of China's reform and opening up in 1978.

In China, the railway is so special. The artery of the national economy -this was the most common description of the railway at that time. In the comprehensive transportation system, the railway has always played the backbone role, and coal, wood, ore, grain, and fertilizer rely on railway transportation for a long time. In addition, railways are popular transportation tools. In the 1970s and 1980s, the railway transportation capacity was insufficient. The pictures of the Spring Festival and early in the railway station were caught in the railway station. According to data, in the 1980s, my country's freight satisfaction rate can only reach about 30%, and it is difficult to find a vote for mass travel.

In 1978, China ushered in a new era of reform and opening up. With the pace of reform and opening up, the Chinese railway implemented a large number of key project construction, and was committed to expanding the scale of the road network. At the same time, it also targets another goal: improve the speed. This must inevitably require a huge and extensive and in -depth basic theory and construction technology research. With excellent scientific research results, Tian Hongqi gradually became a member of this huge technical team. In 1982, Tian Hongqi stayed in school to teach. In 1988, he obtained a master's degree in locomotive and vehicles in the Changsha Railway Institute. China Air Power Research and Development Center, researching and solving air dynamics of rail transit.

As of 2007, the Chinese railway has accelerated 6 times. In the process of continuously promoting the modernization of railways and the modernization of railway equipment, the development of a "high -speed railway" system with a speed of more than 200 kilometers per hour per hour has always been the dream of several generations of railways. However, the high -speed railway system is a concentrated expression of a variety of modern technologies. It involves the field of research is not comparable to modern railways. Since the 1990s, China has begun to focus on scientific research forces, and has launched an integrated research on multi -platforms such as survey design, civil engineering, locomotive vehicles, and operation management.

Tian Hongqi's task is related to a "air" that we are most familiar with but easy to ignore. Although ordinary people can see "air", it is crucial to the safe operation of high -speed trains.

02

It is both an anti -wind, but also a dance with the wind

The air is no longer gentle in front of high -speed trains. The improvement of train operation speed has caused the power of air to affect the performance of the train and train, and the phenomenon caused by the high -speed operation of the train will also affect the surrounding environment. Therefore, how to make high -speed trains better face complex air conditions is an important issue for my country's construction of a high -speed railway system.

For example, my country is vast, and Chongshan and Mountains are crossing all kinds of transportation lines. The design of the high -speed railway tunnel must have a special consideration. When a high -speed train enters the tunnel, the air in front will be squeezed. This squeezing state can spread to the tunnel exit at a speed speed, and then suddenly swell to release a strong air pressure wave to generate instantaneous shock pressure. It will affect the facilities and buildings around the tunnel, and at the same time, a big blasting sound will be produced.

"The study of transient impact pressure during the tunnel was improved for more than 20 years." Tian Hongqi said that she and the team set up a tunnel buffer structure, which will gradually change the pressure. Although the researchers have found that the larger the section of the tunnel hole, the more the air pressure waves generated in the high rate of operation, the more than the engineering perspective, it has a series of problems such as earthquakes, engineering costs, etc. It is a suitable value. "For example, our country's Beijing -Shanghai high -speed rail, its tunnel section is 100 square meters. This section is more appropriate to improving the transitional impact of the train through the tunnel."

As a new generation of scientific researchers after reform and opening up, Tian Hongqi has built my country's railway aerodynamic foundation and engineering technology system, and establishes the method of developing train pneumatic shape structure, optimization of train/tunnel coupling pneumatic structure, and other methods. my country has both railway 250km/h and high -speed passenger line 350km/h safe operation.

It is precisely from generation to generations like Tian Hongqi who have worked unremittingly. From the serious lack of capacity of my country's railway in the 1970s, to now, the total mileage of high -speed railways exceeds 40,000 kilometers, and it is covered with cold temperatures and tropical. To zero 40 degrees Celsius, rank first in the world.

In addition to the world's number one high -speed railway, my country also has a worldwide feat in rail transit, which is the "Qinghai -Tibet Railway".

The area along the Qinghai -Tibet Railway is the main concentration of the plateau wind, with an average annual wind of about 150 days. This terrible wind speed sometimes reaches more than 17 meters per second, and the destructive power is very large. Along the railway, the wind may cause varying degrees of harm to the railway bridge, vehicles, telecommunications equipment, and lines, and even the excessive wind power causes the train to be overturned.

In 2002, the characteristics of studying the wind along the Qinghai -Tibet Railway and the task of proposing corresponding solutions fell on the shoulders of Tianhongqi. At that time, there were no related technologies that can be used for applications throughout the world.

"The Qinghai -Tibet Railway Golmud to Lhasa, most of the altitude is above 4,600 meters. It is an uninhabited area and the wind is very large. In the past, no one studied the situation of the wind and the size of the wind." Tian Hongqi said Without shrinking, the memories of the altitude research work were very romantic. "We are going to chase the wind, and finding the wind is an adventure."

There, the team did 6 years of experiments. One day, the temperature is more than 30 degrees Celsius. Everyone wore short sleeves. Who knows that more than an hour later, the temperature suddenly dropped to minus 20 degrees Celsius, and it dropped more than 50 degrees Celsius at once. Red flags and colleagues under the cold wind and snowflake ice kernels, one stop in the wild for a few hours. The wind was so big that he could blow people away, and Tian Hongqi was holding steel in the snow, tied his waist with a steel rope, and insisted on work. Another time, due to excessive exercise on the plateau, she spit more than ten hours in a row.

In the end, they developed the world's only "plateau railway wind monitoring and early warning and driving command system". This patent, as one of the core technologies of the "Qinghai -Tibet Railway Project", has won the National Science and Technology Progress Award and other prizes. After continuous research and improvement, it is widely used in railway engineering such as Xinjiang Railway, Beijing -Shanghai high -speed railway, and Shanghai -Kunming high -speed railway. This system has been operating so far, and there has never been a driving accident caused by a strong wind. 03

The first female helm of the "top flow" college

Now, cultivating the next generation of scientific and technological talents has become the heavy responsibility of "Tian Hongqi". In 2017, Tian Hongqi was appointed as the president of Central South University, the first female helm at the school.

Central South University is the first batch of national key universities and national "211 Projects" directly under the Ministry of Education.

Tian Hongqi is a "child soldier" cultivated by the school's own. It has been in the school for more than 40 years, but it is not easy to be a principal. At the reception ceremony, she said: "I am deeply responsible and huge pressure. In this new work arrangement, I can only bow my best and dare not slack the slightest."

Today, the female head has been at the helm for 5 years. She rarely was interviewed. As the principal, her voice left to the outside world was mostly related to "focusing on scientific research".

At the graduation ceremony, she warned teachers and students that all research results of Central South University so far were "looking up at the starry sky and down -to -earth", and "soaked" with hard work and sweat. "A person's life may burn or decay. As a student in the south, we cannot decay, we have to burn!"

At the National People's Congress, she called for the conditions of calm learning for scientific researchers and reducing the time used in project declaration; giving more opportunities for young teachers to develop opportunities to allow them to pick up beams and protagonists in scientific and technological innovation.

She is more concerned about the employment and development of female talents. Once, she said with some sadness: "The employment of female college students and graduate students is difficult, especially the employment situation of female college students is increasingly prominent. This phenomenon must be changed." Based on this observation, she has repeatedly many times in the country. The "two sessions" proposed that we must pay attention to the equal employment of female college students.

In the past June, the advice she gave her graduates was full of romance of the times. She said that the changes in the world, the changes of the times, and the changes in history are unfolding in an unprecedented way. ; Only calmness can choose rational choice; only calmness can we do far away.
