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。所做工作有利于提高SLAM的检测灵敏度
In this paper, the transmission law of acoustic wave to lossy sample plate is analyzed and the formula of transmittance | W | 2 is obtained. For both types of sample plates, their response curves | W | 2 / θ1 are numerically calculated, and the maximum value of | W | 2 is obtained by adjusting the angle of incidence θ1. The work done is conducive to improving the detection sensitivity of SLAM
