Founding my country’s firstA specialized research center on hydroacoustic engineering that combines science and engineering with complete supporting facilities. It is the first to develop an international hydroacoustic positioning system and reach the international advanced level. It has solved the problems of water tunnel noise reduction and measurement methods that have been difficult to conquer in the world…
Yang Shie, an academician of the Chinese Academy of Engineering and a professor at Harbin Engineering University, is responsible for the mission of “developing the sea to benefit the country” and providing “ears” and “eyes” for my country’s thousands of miles of sea.
On March 19 this year, Yang Shie died of illness in Harbin City, Heilongjiang Province at the age of 93. As one of the founders of the hydroacoustic engineering discipline and one of the pioneers of hydroacoustic science and technology in my country, Yang Shie has made important contributions to the development of hydroacoustic technology in my country.
Self-sufficient, from Starting from scratch, engaging in marine scientific research
Yang Shi’e was born in 1931. His childhood was during the war. In his wandering life, he gradually planted the seeds of scientific research to serve the country.
When Yang Shie was young, he thought that participating in naval construction could not only fulfill his long-cherished wish to serve the country, but also find a suitable and competent position in national construction.
In 1950, Yang Shie chose to graduate from Tsinghua University After graduating from the Department of Physics at night, he signed up to join the army, taught at the First Naval School in Dalian, and devoted himself to marine scientific research with passion. From then on, Yang Shie’s resume always said “graduated from Tsinghua University”.
In 1952, the predecessor of Harbin Engineering University was the Military Engineering College of the People’s Liberation Army of China. In preparation for the establishment, Yang Shie came to Harbin and took root in this dark land. At that time, the subject of hydroacoustics was still blank in the country, and the country selected Yang Shie and four other people to study abroad.
From university to studying at foreign research institutes, Yang Shie has never forgotten the needs of the country. He believes that hydroacoustic research is of great significance to national security.
During his study abroad, Yang Shie became familiar with He realized that in the key field of national defense technology, core technology is an important weapon of the country and must be self-sufficient. It cannot be relied on or relied on by others. This strengthened his determination to tackle key problems in the field of hydroacoustic science: China must have its “ears.” “Understand the sound of the sea.
Self-sufficient, starting from scratch. After returning to China, Yang Shie devoted himself wholeheartedly to my country’s hydroacoustic scientific research work, which he did for nearly 70 years.
Leading the team to conduct large-scale deep sea acoustic surveys
Thirty years ago, as the captain and chief scientist of the inspection team, Yang Shie and China Hydroacoustic Research The personnel embarked on a scientific research vessel to launch the first large-scale deep-water acoustic survey independently commanded and conducted by Chinese scientists, taking the first step in China’s hydroacoustic field to cross from shallow seas to deep seas.
When working in the deep sea area, the sun near the equator shines almost vertically, and the surface temperature of the ship reaches more than 70 degrees Celsius. Yang Shie, who is over 60 years old, has been experimenting at sea for a long time, and has been able to persist in the hot and water-deficient surrounding conditions. Test stopped.
After the assessment team members fell asleep after a tiring day, Yang Shie ensured that the personnel and equipment were safe and continued to study the follow-up test plan. He was well aware of the years of expectations and expectations of the Chinese underwater acoustic community. It is not easy to prepare and fund the state, and the assessment tasks must be completed.
The investigation has obtained rich and credible test data, accumulated a large amount of valuable first-hand information, and exercised a lot of vitality for China’s hydroacoustic work… What makes Yang Shie happy is that based on this, more than 20 years later, China’s hydroacoustic research has moved towards a broader deep blue sea.
When Yang Shie was 88 years old, he still participated in the seaJM EscortsExperiment “How can you do a seminar without being on site? Any difficulty must be overcome. When it is time to persevere, you must grit your teeth and face the difficulties. The sea is unpredictable, so sitting at home and doing research is definitely not possible. ” Yang Shie said.
DozensIn the past year, Yang Shie led the team to complete the development of China’s first intercontinental missile “Impact Point Hydroacoustic Measurement System”, laying the foundation for the domestic high-precision ultra-short baseline positioning system used by the “Jiaolong” and “Science”; he was in charge of the design and Build China’s first “gravity-type low-noise water tunnel” for research on low-noise water tunnels…
Based on the country’s major strategic needs, from China’s hydroacoustic technology pioneering to vigorous development to innovation promotion Going global, Yang Shie has always been a vanguard and leader.
Stick to the three-foot podium and cultivate scientific research talents
“As long as it is a country or a society What is needed is worth doing. “In September 2022, the video of Yang Shie, an academician born in the 1990s, giving a class to those born after 2000, flooded the circle of friends. This 91-year-old academician of the Chinese Academy of Engineering is known as the “one-stop academician.”
Since he has been teaching for 70 years, he has always taught students while standing. “While teaching while standing, I can add movement, which is comfortable and abstract. ” Yang Shie said.
Scientific research and educating people has always been a job that Yang Shie can’t let go of.
Yang Shie founded my country’s first science and engineering university at Harbin Engineering University Jointly, Jamaicans Escort has a complete set of specialized research on hydroacoustic engineering, which has improved the level of hydroacoustic education in China. Talents from here occupy the entire country. The world of hydroacoustic research is in tatters, and the school is therefore known as the “cradle of hydroacoustic work in China.”
Now, Harbin Engineering University has become a talent pool, expert pool and basic research center for hydroacoustic technology for the development of national hydroacoustic work. More than 60% of the specialized research technicians and more than 70% of senior experts in my country’s hydroacoustic industry are from here. Get out.
“At your level, are you still studying such a basic programming tool? “Yin Jingwei, a professor at Harbin Engineering University, recalled the experience of visiting Academician YangJamaicans Escort. “I have to study more seriously, not Don’t teach students wrong knowledge. “Yang Shie’s answer made Yin Jingwei full of respect for the teacher’s rigorous attitude towards academic research and his sense of responsibility towards his students.
Standing to the three-foot podium, Yang Shie cultivated There are more than 110 master’s and doctoral students, and he has taught thousands of students. Most of his students have grown into scientific research and academic backbones in related fields at home and abroad, and have made important contributions to the development of hydroacoustic work in China. p>
Rooted in Harbin Engineering University and working in the field of hydroacoustic engineering, Yang Shie has been listening to the sound of the sea for decades and dedicated his life to the cause of building a powerful ocean. (This newspaper Reporter Zhu Dawei)
