Recently, the Central Committee of the Communist Youth League and the All-China Youth Federation announced the results of the 25th "Chinese Youth May 4th Medal". XD 2015 alumni Liao Jiawei is a working unit of the Institute of Acoustics, Chinese Academy of Sciences "Struggle" The acoustic team of the all-sea deep manned submersible was awarded the title of "Chinese Youth May 4th Medal Collective". At the same time, as a representative of the "China Youth May 4th Medal Collective", Liao Jiawei boarded the CCTV May 4th Party to report and shared his personal experience and insights in the development of acoustic equipment for the "Struggle" all-sea deep submersible.

Liao Jiawei's unit, Institute of Acoustics, Chinese Academy of Sciences, "Struggle" full-sea deep manned submersible acoustic team developed the acoustic system to realize the underwater acoustic communication, positioning, navigation, attitude measurement, flow measurement, speed measurement, obstacles of the submersible on the seabed of 10,000 meters Object detection, small target search, and submarine fine topographic mapping and other functions are the core system of the submersible. The team is responsible for the technical research on the acoustic system of the Struggle and has a total of 23 scientific researchers. Among them, 16 people are under 35 years old, accounting for 69.6%; 19 people have a master's degree or above, and young and middle-aged researchers with high education have become the backbone of the team.




When participating in an interview with CCTV, Jiawei Liao said that he was lucky to be able to participate in the development of the whole-sea deep manned submersible project just after graduation. Since entering, my colleagues and I have participated in many lake-sea trials and have experienced lake water. The calmness of the sea, the magnificent waves of the sea, the scorching sun, and the late-night duty on the deck. During the epidemic, he was stationed at the assembly joint inspection site for more than 5 months. When I saw the "Struggle" completed the 10909-meter deep sea in the Mariana Trench At that time, pride and pride emerged spontaneously. As a new era fighter, I deeply realize that participating in technological innovation must have the courage to “dare to do it, dare to do it by yourself”, especially underwater acoustic communication. In the face of long-term technical blockades abroad, I always remind us that we must continue to walk in At the forefront, there must be "Never-Stopping Scientific Research." In the future, I will keep in mind the school's mission of "Serving the people wholeheartedly" of my alma mater, and achieve a career in real work, so that youth will bloom in the unremitting struggle for the motherland, the nation, the people, and the mankind.
