声学

Most of the sound field simulation focuses on researching the impulse response in closured sound field,and then calculates other sound parameters,due to various environment in outdoor sound field,there is less research.

大部分声场仿真侧重于在室内封闭声场的前提下研究声场能量脉冲响应，进而获得其他声学参数，而室外声场环境由于差别较大，考虑因素较多因此研究较少。

This study deals with many branches of modern mechanics, such as structural dynamics, damage mechanics as well as coupling of multi-media and multi-fields. Therefore, the research on structural dynamic properties and underwater acoustic properties of intact and delaminated composite plate structures is not only of great theoretical importance but also of practical value.
