| 本文利用惠更斯－菲涅尔原理和虚源方法建立了均匀海水中障碍物后声传播损失的计算模型，对模型进行了数值实验验证，并与海上试验数据对比，得到了较为合理的结果。 |
| 英文摘要: |
| This paper presents a numerical calculation model of the transmission loss of acoustic field behind obstacles in homogeneous water based on Huygens-Fresnel principle and the method of virtual source. The model is verified through a numerical experiment,whose results agree quite well with the data of the marine practice. |
