| 摘 要： | 延庆地震台五里营井逸出氦气受该井动水位异常变化影响,每日数据扰动大,影响原来的日变形态.对仪器的集气装置进行改造,把地面集气改为水下集气.既解决氦气受水位异常变化的影响问题,减小观测环境变化对氦气观测的影响,提高观测质量,对今后可能记录的地震前兆信息提供保障,对其他有此测项的台站有一定借鉴意义. |

| Abstract: | The daily helium observation data of Wuliying well affected by the effect of the changes of water level at Yanqing Seismic Station. We analyze the working principle and gas collecting method of WGK-1, and alternate the mode of the gas collection instrument-under-water instead above ground, which solve the problem of the effect of the water level and observing environment to the helium observation. So, the instrument records the normal daily-values again, and would offer the insurance for recording the earthquake precursor information. All the above methods could supply the reference value for the other station possessing the heli- um observation. |
