摘　　要：对2008年3月奇村热水井数字化水汞观测数据出现波动幅度较大、持续时间较长的异常情况进行了追踪分析。通过对现场周围环境调查、仪器运行状况、对比观测实验及观测资料的对比分析等,认为更换仪器、仪器K值变化大是造成数据波动的主要原因。In Mar.2008,digital water mercury observation data of thermal water well in Qicun showed variations with relatively larger fluctuation range and longer duration.The authors carried out tracing analysis on it through field survey of surrounding environments,instrument running condition,comparative experimental observation,comparative analysis on observation data and so on,and thought that replacing instruments and instrument K value changing greatly were main reasons that caused data fluctuation.
