- 海洋环境－已发表论文 
利用纵振换能器的纵向振动与换能器前盖板的弯曲振动相耦合原理 ,采用纵振换能器与声反射器配合 ,研制出一种适应在复杂海洋声信道进行高速率传输 ,具有低频、宽带、大功率等优点的水声换能器This paper introduces a kind of projector which is fit to be used in high speed communications on complex sea acoustic channels. The acoustic transducer has the characters of low frequency, wide band and high power. It has been obtained by both coupling the longitudinal vibration of transducer with the curved vibration of the projector front panel,and combining the longitudinal vibrant transducer with the reflector.
