【摘要】 <正> 在W.H.Pelton等（1978年）发表的频谱激电法区分矿物和消除感应耦合的论文中,他们在北美26个矿区进行了大量的露头观测,发现充电率都很高的块状硫化矿和石墨,它们的时间常数有3—4个级次的差别。据此,提出了由稀释系数将视电阻率频谱转换为真谱,求得真时间常数,根据真时间常数之间的差别,对异常源矿物类型进行区分。 稀释系数B₂的表达式为更多还原

【Abstract】 Pelton et al.[1] have used the dilute factor for the resistivity spectral transformation for bodies with high chargeability. We have pointed out that this dilute factor which was derived by H. O. Seigel in 1959 can only be used under the condition of low chargeability of the researched body. This opinion is also proved by the results of our experimental work.更多还原
