本文根据地震前地壳中由于地应力场的变化而会引起地温变化的想法,阐述了对埋在地下三米深处的温差电偶用电桥所测出的阳江县1973年地温日变化曲线与当地二级以上小地震在时间、地点及震级方面的经验关系。为寻找前兆现象提供一点资料。
Based on the idea that the ground temperature changes in the crust before the earthquake due to the change of the geostress field, the paper describes the diurnal variation curve of geothermal temperature in Yangjiang County in 1973 measured by the bridge with thermocouple buried in the ground three meters deep The empirical relationship between small earthquakes level two and above in time, place and magnitude. Provide some information for looking for precursors.
