摘    要：伪随机三频波激电法具有高精度、高效率,仪器设备轻便,抗耦、抗干扰能力强,信息量丰富等特点,本方法适合快速普查和详查及工程勘探,1发送机可配多台接收机同时工作,也可采取主剖面和旁侧剖面一道工作,便于进行频谱测量,还可利用频率接头点处的非线性效应深入研究异常源的性质。

Abstract: The pseudorandom triple-frequency induced polarization method has the advantages ofrapid survey ,high precision,portability,removal of inductive coupling effects,high noiserejection,and high data density.This method can be amplied in detailed survey and engi-neering exploratiOn as well as reconnaissance with a transmitter and more receivers to makemeasurements including spectrum of frequency over both main profile and lateral profile simultaneously. Moreover,the fact that the sawtooth anomalously exists on the overlap pointsamong frequency groups indicates the nonlinearity of frequency spectrum and is the useful in-formation about the sources.
