| 摘 要： | 采用传递矩阵方法,推导给出水下单层非弹性均匀材料层和弹性均匀材料层的声反射、透射系数公式。设计并进行不同厚度钢板和玻璃钢板的声反射特性的对比实验。理论计算结果和实验结果符合,在水中钢板表现出绝对刚性的声学特性,而玻璃钢板由于特性阻抗小于钢板并且较厚,反射特性具有明显的振荡特性。

| Abstract: | By means of Transfer Matrix Method,the reflection and transmission formulas of underwater homogeneous nonelastic and elastic monolayer have been derived.The contrast test of reflection characteristics for different thick steel plate and glass fibre reinforced plastic plate has been conducted.The theoretical calculation results agree with the contrast test,and show that steel plate has the rigid acoustic characteristic.The natural impedance of glass fibre reinforced plastic plate is less than steel plate,but more thick.So its reflection characteristic is obvious oscillating. |
