论述了电声互易原理和用于平面活塞型与球面聚焦换能器校准的自易法(Self Reciprocity Method, SRM)。介绍了一系列的定义和发送电压(电流)响应与电压灵敏度。阐述了SRM与辐射力天平(Radiation Force Balance, RFB)法之间的关系。在1~25 MHz 频率范围内，对超声换能器校准和输出功率测量的实验显示，两种方法具有相近的准确度。SRM法比RFB法测量具有更高的信噪比和更好的稳定性。

The principles of electroacoustic reciprocity and self-reciprocity method (SRM) for the plane piston and the spherically focusing transducer are described. A series of definitions with uses of transmitting voltage (current) res-ponses and voltage sensitivity are introduced. The relation of SRM with the radiation force balance (RFB) is ex-pounded. Experiments in frequency range of 1.0~15 MHz show that the two methods are of close accuracy in calibra-tion and output power measurement of ultrasonic transducer. The measurement by SRM is of high signal noise ratio and better stability than by RFB.
