深潜水声世界 倾听海洋“心跳”

Core Viewpoint - The article commemorates the life and contributions of Ma Yuanliang, a prominent figure in underwater acoustics and sonar technology in China, who passed away at the age of 87, highlighting his pioneering work and lasting impact on the field [1][5]. Group 1: Early Life and Education - Ma Yuanliang was born in 1938 in Sichuan and initially aimed to study physics at Peking University, but shifted his focus to national defense in 1956, enrolling in the Northwest Institute of Technology [1][2]. - He was among the first students to study underwater acoustics when the program was established in 1958, later becoming one of the eight students sent for advanced training at the Military Engineering Academy [1][2]. Group 2: Career Achievements - During his early career, Ma led the development of the "K4 sonar measurement device," which was showcased during the 10th anniversary of the founding of the People's Republic of China, igniting his passion for underwater acoustics [2]. - At the age of 27, he became the chief designer of China's first helicopter-deployed sonar system, overcoming challenges to successfully develop the first aviation sonar by 1976, which won a national science award in 1978 [2][3]. - His visit to France in 1978 inspired him to innovate, leading to a new sonar system that achieved detection ranges 2-3 times greater than Western counterparts by 1981, marking a significant leap in technology [2][3]. Group 3: Educational Contributions - Ma Yuanliang emphasized the importance of education alongside research, establishing China's first doctoral program in underwater weaponry and mentoring the first doctoral student in the field [4]. - He encouraged students to adopt a "nail spirit," which emphasizes perseverance and dedication in overcoming scientific challenges, fostering a culture of innovation [4]. Group 4: Legacy - Ma's commitment to combining teaching and research reflects his belief in the importance of passing on knowledge and values to future generations [5]. - His contributions to underwater acoustics have left a lasting legacy, inspiring future researchers to explore deeper and broader realms in the field [5].
