【摘要】 对比分析了北京市地震局丰台大灰厂井和延庆五里营井的氦气观测资料,发现由于井水深度、井水类型和水温的不同,丰台大灰厂井氦气含量明显低于延庆五里营井的氦气含量;两口井氦气年变都是冬高夏低;日变形态基本一致,都表现为一峰一谷的形态;两口井氦气含量与观测环境温度负相关。更多还原

【Abstract】 Helium gas observations of Dahuichang well at Fengtai and Wuliying well at Yanqing of Beijing earthquake administration are contrasted and analyzed.It is found that Helium gas content of Dahuichang well at Fengtai is obviously lower than that of Wuliying well at Yanqing because of the difference of depth of well water,type of well water and water temperature.Annual variation of Helium gas of the two wells are both high in winter and low in summer.Daily variation shapes are basically consistent and both have the shape of a peak and a valley.Helium gas content of two wells are both correlative negatively with their observation circumstance around.更多还原
