岩石电阻车不仅具有频散特性，而且会因频散作用而造成阿尔奇公式中各种参数的变化。本文系统地介绍了岩石电阻率频散的影响因素及饱和度指数、胶结指数与频率之间的关系，认为实验室进行阿尔奇公式参数测量应采取多频测量。
Rock resistance car not only has dispersion characteristics, but also due to dispersion caused by Archie formula in a variety of parameters change. This paper systematically introduces the influence factors of rock resistivity dispersion and the relationship between saturation index, cementation index and frequency. It is considered that multi-frequency measurement should be taken in laboratory for Archie formula parameter measurement.
