摘要： 汞是地下流体监测预报地震的灵敏组分之一,针对目前汞观测网中出现的突出问题——汞测量方法中的干扰因素进行了剖析,指出蒸馏水、化学试剂、温度和吸附作用是造成观测结果波动大的主要原因,并提出了减少误差、排除干扰和识别异常的方法。

Abstract: Mercury is one of the sensitive constituents in subsurface fluid for earthquake moni-toring and prediction. Authors analyzed interference factors in the process of mercury ob-servation in groundwater, and pointed out that distilled water, chemical reagents, temper-ature and adsorption mainly cause the variation of background data. Finally, the methods for elimination of contamination and identity of anomalies are presented.
