摘要
双频激电仪的误差大小将直接影响测量精度,从而影响到对地质异常的正确判断,因此,设计一种简易可靠的测试网络,对仪器性能进行检测、校验、判定,具有实际意义。作者在实验室用这种RC网络模拟了激电效应,用以考察双频激电仪的一些性能指标及其反映激电异常的能力,取得了令人满意的效果。
Dual-frequency IP instrument is a kind of precise electronic instruments, and its error has strong influence to survey results. In order to check the characteristics of dual-frequency IP instruments, the authors have designed a simple RC-circuit. The authors have done the simulation test, and gotten satisfactory results.
