本文利用力因子提出了n对IDT电声转换的新基本方程。由这些方程推导出简化的三端口等效电路。作为一种应用，在两个声学端口中的一个与特征阻抗相连的情况下，IDT的两端口等效电路也以更简单的形式推导出来。
This paper presents the new fundamental equations of electro-acoustic conversion for N-pair of IDT by using force factors. From these equations, the simplified three-port equivalent circuits have been derived. As an application, in the case that one of two acoustic ports is connected with the characteristic impedance, the two-port equivalent circuits for an IDT have also been derived in much simpler forms.
