摘　　要：由一维非均匀介质波动方程,推导出更广泛适用的阻抗率方程。该方程把复杂的二阶偏微分波动方程求解问题转化为一阶阻抗率方程求解,方便了非均匀材料的声透射性能的计算。该方法对分析复杂介质透射问题非常有效。In this paper, the impedance equation was deduced by one-dimensional inhomogeneous medium wave equation. The problem of Complicated second order partial differential wave equation was changed into a problem of first-order differential equation. Inhomogeneous medium wave equation can conveniently be used to calculate the transmission spectrum. The method was proved to be very effective in the analysis of complex medium transmission problem.
