| 摘 要： | 通过对唐山地震气象背景分析，揭示了唐山和昌黎两个测站的80cm地温日变率在震前4天分别突升1．1℃和1．2℃。对这种异常现象进行了天气气候分析，震中区与外围站对比分析以及滤波分析等，并论证为是来自地下深处影响所致。还对震前地温突升成因给与一定的解释。

| Abstract: | The ground temperature in Tangshan and Changli Observatory suddenly increased 1. 1℃C and 1.2℃ respectively 4 days before Tangshan earthquake. Based on the weather background before the earthquake, the abnormal phenomenon is analyzed. The comparison of epicenter region with outside area as well as filtering analysis showed that the anomalies were caused by deep factors. Some explanations to the cause were also presented. |
