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。
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 si-multaneously. 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.
