However, the use of convolution model is to deduce recursion formula of the reflection for the converted wave.
而利用褶积模型理论解决转换波问题的关键是建立转换波反射系数递推公式。
First, the impact model of the linear system was built, and the basic analysis principle and calculation formula were derived. At the same time, the convolution integral formula was also given.
