备注

对观测室环境和观测时间改变对水汞观测数据产生的影响进行了实验研究和分析,详细介绍了一次水汞测值异常的核实过程,得出以下结论:(1)观测环境及观测时间的改变不会对水汞观测结果产生明显影响;(2)由于观测室内会残存汞蒸汽,应将观测室随时保持通风状态以降低观测室残存汞蒸气对水汞测值的影响;(3)要加强对试剂、观测室空气中汞含量的监测,避免外界条件变化对水汞观测结果带来的影响。

Based on experimental study and analyzing of the influence of the environment in observation room and observation time change on water mercury data,we described the verification process of water mercury anomaly in detail.Conclusion s are drawn as follows:(1)The observation environment and observation time change have not significantly influence on water mercury observational results;(2)There exit a few mercury vapors in the observation room,we should keep the observation room in the state of ventilation in order to reduce the influence of residual mercury vapors on the water mercury observation results.(3)We should strengthen monitoring the reagent and mercury content in the air of the observation room to avoid the influence of external conditions change on the water mercury observation results.
