摘要
断裂带氢气浓度连续观测是获取深部构造活动的重要气体地球化学指标之一。由于断裂带岩层氢气浓度背景值较低,因此检验和分析氢气观测仪器的绝对检出限以及仪器稳定性便是选择高效能氢气浓度观测仪器的重要环节。在中条山山前断裂的夏县东郭测点开展了同一取样点相同环境的2套痕量氢气观测仪器对比实验,从记录的资料分析,两条曲线变化趋势、变化形态基本一致,但在细节上稍有差别,通过拟合分析,使用相关系数进行校正后,两条曲线基本重合。结果表明,痕量氢气自动分析仪稳定好,灵敏度高,观测结果一致,且实现了数字化,能够满足地震活动监测工作的需求。
Continuous observation of hydrogen concentration in fault belt is an important gas geochemical index on deep tectonic activities. Because of low hydrogen concentrations in fault rocks,absolute detection limit and stability are important factors in choosing the observation instrument. Experimental comparison study of two sets of trace hydrogen observation instrument in the same sampling location and under the same environment was carried out in the piedmont fault zone of Zhongtiao Mountain. The observed results show that two curves recorded by two instruments display almost the same changing tendency and forms with slightly differences on details. After the fitting analysis and correction by the correlation coefficient,two curves are nearly overlapped. This result reveals that the automatic trace hydrogen analyzer has good stability,high sensitivity,digitization,and consistence with the observed results,which is able to meet the needs of earthquake monitoring, and provide safeguard for the new observation technology of seismic precursor.
