【摘要】 <正> 地壳温度测量在地球物理学及地震预报研究中都具有重要意义。在钻孔中进行温度梯度测量并与岩石热导率的测定相结合,可取得大地热流数据,以此可全面表征地表热场并展示地球内部热状态。在地震预报研究中,地温观测既可作为一种地震前兆观测手段,也可作为一种辅助观测项目,以便从其它观测手段中排除环境温度变化造成的影响。更多还原

【Abstract】 By using the digital borehole thermometer (Model SZW-1), temperature and temperature gradient measurements have been made in four boreholes which are respectively located at Dongsanqi, Mafang, Dagaocun and Wangcun in the northern part of North China. The results show that the temperature changes are related to the flowing ground water or the various layering thermal conductivity. The heat flow values of the two wells at Dagaocun and Wangcun are also calculated by utilizing the thermal conductivity data obtained from the adjacent, areas.更多还原
