The resistivity is then constant and ohm's law is obeyed . 因此电阻率也是常数，并遵循欧姆定律。
We can see that the massive vein is revealed by resistivity . 可以看出，致密的矿脉可用电阻率法来发现。
Electrical resistivity is used widely as a measure of brine saturation in rocks . 电阻率被广泛地用于测量岩石中的矿化水饱和度。
The resistivity contours appear much less diagnostic of anomalous bodies below the surface . 地面下方的异常体，在视电阻率等值线上并无明显的反映。
The salinity of the water in the pores is probably the most critical factor determining the resistivity . 孔隙内水的矿化度或许是决定电阻率的最主要因素。
This is the theoretical expression for the resistivity, and it is in qualitative agreement with experiment . 这就是电阻率的理论表达式，它与实验定性地符合。
Let us now consider polarizable bodies whose resistivities are similar to that of the geological environment . 现在我们来研究电阻率与地质介质相同的极化体。
Em, like resistivity, can also give structural information: faults, shear or altered conductive areas . 和电阻率法一样，EM法也能提供构造方面的资料，如断层、剪碎带或蚀变导电带。
A problem which is often attacked by resistivity measurements is to locate the depth at which saltwater invades fresh water in aquifers . 经常用电阻率测量来攻克的问题是确定含水层中盐水侵入淡水的深度。
The resistivity of some of the insulating materials mentioned above is temporarily impaired by exposure to a few thousand roentgens of x radiation . 上述的某些绝缘材料在受到几千伦琴的X辐射照射后，其电阻率会出现暂时性的减少。
