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。
Mercury is one of the sensitive constituents in subsurface fluid for earthquake monitoring and prediction. Authors analyzed interference factors in the process of mercury observation in groundwater, and pointed out that distilled water, chemical reagents, temperature and adsorption mainly cause the variation of background data. Finally, the methods for elimination of contamination and identity of anomalies are presented.
