The electrical resistivity of some metals seems to vanish altogether at temperatures a few degrees above absolute zero . 温度在绝对零度以上几度时,有些金属的电阻似乎消失了。
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。
Although not a precision instrument, the ohmmeter is a useful device for rapid measurement of resistance . 欧姆计是一种很有用的仪表,可以用来迅速地测量电阻,尽管它不是一种精密仪表。
But their resulting inductive reactance is completely swamped by the resistance resulting from their being scattered in the metal . 但由此所产生的感抗完全被其在金属中受到散射而产生的电阻掩盖了。
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。
