| 摘 要： | 采用ATG-6118H痕量氢在线自动分析仪，在朱夏-商丹断裂带南阳地区布设独山、马山口2个氢气观测台，研究设备取气深度、抽气时间设置长短对观测断层氢气浓度的影响，从而为利用痕量氢设备进行断层氢气观测提供参考依据。实验结果表明：①取气深度越浅，观测到的氢气浓度越高，日变化幅度越大；②集气管内氢气浓度偏低时，抽气时间设置略高于导气管路排空时间，氢气浓度明显变化，否则变化不明显。

| Abstract: | Using ATG-6118H on-line automatic trace hydrogen analyzer, in Nanyang region Zhuxia-Shangdan fault zone layout Dushan and Mashankou hydrogen stations, research facilities taking gas in the depth, equipment fault extracting time set length on the observation the effect of hydrogen concentration, hydrogen to use trace hydrogen equipment fault observations provide a reference basis. The experimental results show that:① In spirit depth more shallow, observations of hydrogen concentration is higher, the daily variation amplitude is larger;②Sets endotracheal hydrogen concentration is low, the extraction time is set to slightly higher than the airway road transit time, changes can be observed clearly hydrogen concentration, extraction time setting is too long, cannot detect hydrogen concentration change obviously. |
