频谱激电法研究中的几个问题

复电阻率法在国外已有三十多年的历史。首先是“变频法”,接着是“相位激电法”,现今已综合发展成以测量振幅和相位谱为主的“频谱激电法”。目前,国外在实验室和野外研究的基础上,正致力于把频谱激电法推进到野外实际调查中去。加拿大凤凰物探公司新近制造的商售IPV-3系统就是专为推进频谱激电法而设计的。

SOME OBSERVATIONS IN THE STUDY OF SPECTRALINDUCED POLARIZATION METHOD

Theoretical investigation, model test and analysis of the data available all suggest that the research on complex resistivity spectra is subject to certain limitations if only amplitude spectrum and phase spectrum are used. As a remedy, an integrated utilization of amplitude, phase as well as real and imaginary component spectra makes it possible to derive the reliable initial values of such spectral I. P. Parameters as r, m and c by means of simple procedures in fitting and inversion computations, which in turn will contribute to a further shortening of the fitting and inversion process.
