| 中文摘要: |
| 本文参照空气声学的方法，在水池的半混响环境中，测量了两个相似加肋圆柱壳模型的水下辐射声功率，并利用声辐射的理论相似关系进行校验，在高频段测量偏差为１－２ｄＢ． |
| 英文摘要: |
| In this paper, the radiating sound powers of two stiffened cylindrical shells are determined in an underwater semi-reverberant environment. The measurement method is verified by similarity relation of underwater acoustic radiation, which shows that the difference in the measured results is about l-2dB at the higher frequency range. |
