进行每天一次定点、定时、定量人工取样观测的下关温泉水汞进行24小时整点人工加密取样观测实验,研究并讨论人工取样水汞24小时日变化与日测值的关系,为汞量异常时的人工加密观测提供预研究依据,以期更好、更充分地捕获水汞前兆异常信息。
By manually sampling hour by hour for 24 hours then observing Hg one by one in same instrument in Xiaguan hot spring, which we have conducted regular daily observation (one time per day) of water mercury for a long time, we studied and discussed the changed characteristics and the relationship between the hourly value and the daily value of Hg. This test aims to provide prestudy and reference for enhancive observation after daily abrupt anomaly of Hg appears and tries to get abundant and dense precursory anomaly information of Hg in hot spring before strong earthquakes.
