摘要
通过对入射波、反射波和透射波振幅和声压的定量比较,得到了声波垂直入射在分界面处位移和声压的反射系数和透射系数,并对各种情况下的反射波和透射波进行了分析讨论.
By the comparison of vibration range and sound pressure of incidence wave, reflection wave and transmission wave the coefficient of reflection and coefficient of transmission of vibration range and sound pressure in the plane of demarcation plane when sound wave vertical incidence. The reflection wave and transmission wave under all kind of cases are analyzed and discussed.
