"The world needs science, and science needs women". At present, female scientific and technological workers are showing their skills in physics, medicine, artificial intelligence, the Internet and other fields, using science to change the world and benefit mankind. On the occasion of the 38th Festival, let us walk into them together and pay tribute to the strength of the mainland science and technology innovation field!
Chief designer of Fuxing - Liang Jianying
From the snowy plateau to the Jiangnan water town, China's high-speed railway continues to extend and cover the whole country, becoming an indispensable means of transportation for people's daily travel, among which the familiar "Harmony" and "Fuxing" have her figure.
She is Liang Jianying, director of the National High-Speed Train Technology Innovation Center. In 2004, the state began to vigorously develop high-speed railways, introducing 200 kilometers per hour EMUs for digestion, absorption and innovation. "Products can be bought, but technological innovation capabilities cannot be bought." With this idea, in 2006, Liang Jianying began to serve as the chief designer, developing a high-speed EMU with a speed of 300 kilometers per hour. In December 2007, the first EMU with a speed of 300-350 km/h in China was successfully launched. In 2008, Liang Jianying took on the task of developing the CRH380A new-generation high-speed train, and finally created the world's fastest speed in railway operation test with a speed of 486.1 kilometers per hour. In 2013, she presided over the development of the "Fuxing" EMU to achieve commercial operation at a speed of 350 kilometers per hour, making the mainland the country with the highest commercial operation speed of high-speed rail in the world. In 2021, the high-speed maglev transportation system with a speed of 600 kilometers per hour developed by her team successfully rolled off the line, marking that Mainland has mastered the complete set of high-speed maglev technology and engineering capabilities.
From "Harmony" to "Fuxing", Liang Jianying, as a technology leader, led the R&D team to overcome difficulties and successfully developed China's high-speed EMU genealogy products from 200 kilometers per hour to 350 kilometers per hour and adapted to various complex operating environments, helping China's high-speed rail to become a bright national business card.
The strongest brain of the 12306 system - single apricot flower
From queuing up to buy tickets at the window in the past to being able to book and buy tickets without leaving home, China's high-speed railway network has achieved rapid development in just over a decade, which is inseparable from the efforts of Shan Xinghua and her team.
In 1996, the research and development project of China Railway ticket sales and reservation system was launched, and Shan Xinghua, who was still in graduate school at that time, was selected into the project team, which opened her indissoluble relationship with the railway ticket system. In 1997, Nanchang Station operated the computer ticketing system for the first time, and since then, the system has been continuously upgraded from version 1.0 to version 4.0, and Shan Xinghua participated in the whole process. In 2005, Shan Xinghua singled out the research and development promotion of version 5.0. In 2010, with the rise of "Internet +", Shan Xinghua and her team began to develop the railway 12306 Internet ticketing system, and in 2011, the railway 12306 website was officially launched, marking that China's railway has entered the era of e-commerce.
From manual ticket sales to computer ticket sales, from independent ticket sales at stations to national online ticket sales, Shan Xinghua participated in the transformation of the whole process, from learning assistance, being alone, to being in charge and overall design. Today, the 12306 ticketing system has developed into the world's most visited and traded ticketing trading system, and Shan Xinghua, as the leader of the research and development project, is also known as the strongest brain of the 12306 system.
The first person in Asia - Hu Hailan
According to data from the World Health Organization (WHO), the cumulative number of people with depression in the world exceeds 350 million, which has seriously affected human health. How to treat depression has become an urgent problem to be overcome, and her and her team's research has brought a new dawn to the prevention and treatment of depression.
She is Hu Hailan, a professor at Zhejiang University. She and her team are committed to studying the molecular and neural circuit mechanisms of emotion and social behavior, and have achieved a series of original results in the past six years in the direction of neural coding of emotions, molecular mechanisms of depression, and the neural basis of social hierarchy. Her team revealed for the first time the brain mechanism that causes depression, provided a number of new molecular targets for the development of new antidepressant drugs, promoted the development of a new generation of antidepressants, and brought hope to 350 million depressed patients.
In 2019, the IBRO-Kemali Foundation awarded Professor Hu the "IBRO-Kemali International Award" in recognition of his achievements in the fundamental neurobiological mechanisms of emotions and affective behavior, which is the first time that the award has been awarded to scientists outside Europe and North America, and Hu Hailan is also known as "the first person in Asia".
