摘　　要：本文分析了声波对有损耗样品板的透射规律 ,得到了透射率 |W |2 的公式。对于两类样品板 ,通过数值计算得到了它们的响应曲线 |W |2 /θ1,通过调节入射角θ1得到 |W |2 的最大值。In this paper,the transmission of an acoustic wave through a lossy plate immersed in water at oblique incident is analyzed. The transmissivity of the acoustic wave are formulated. For two kinds of the sample plates,the response curves of |W| 2/θ 1 are digitally calculated. The maximum of |W| 2 can be got with adjusting incident angle θ 1. It is good to improving SLAM nondestructive testing sensitivity.
