摘　　要：计算2009年3月20日发生在东经124.9°、北纬43.4°的吉林省四平的Ms4.3地震的天体引潮力周期变化过程,并据该周期,分析多源综合温度数据资料,提取地震过程的异常温度变化图像,结果表明:天体引潮力对地应力处于临界状态的活动断层具有诱发作用,震前异常增温明显,异常增温经历了:起始→加强→高峰→衰减→平静的演变过程。对此次微震的研究结果表明温度异常在微地震中也有清晰反映,微震过程中引力作用明显,是对地震-热异常的有力证据,同时也是对利用热异常预测地震方法科学性的补充证实。Calculating the tidal force of celestial bodies during the Ms4.3 earthquake cycle process,occurred on March 20,2009 in the east longitude 124.9 °,north latitude 43.4 ° Siping,Jilin Province,and according to the cycle of integrated multi-source to analyze the temperature data to get earthquake images of the abnormal temperature.The result indicates that the tidal force of celestial bodies has a triggering effect on the activity of the tectonic.The temperature abnormal increase can clearly reflect the process of the seismic fault activity： initial temperature rise →enhancement →reaching peak →attenuation →return to baseline.This study shows that the temperature anomalies in the micro-earthquakes are also a clear reflection of the process of gravitational effect obviously.It is an earthquake-strong evidence of thermal anomalies,also for the use of geothermal anomaly to earthquake prediction.
