- 地电阻率场地的噪声水平将直接决定地电阻率的观测精度，决定观测结果是否适合地震预报的需要。本文主要分析了早年规范和现行标准对场地噪声定义的一些问题，试图给出一个比较适合观测的场地噪声水平。
The noise level of earthresistivity field will directly determine the observation precision of the resistivity, and is the crucial factor to distinguish whether or not the observations are available for the earthquake prediction. In this paper, some problems about the noise of the existing norms and standards of the early years are analyzed for the purpose to present a more appropriate site noise level for observation.
