通过对河北省及邻近地区1980～1997年地震前兆异常信度按时间进行合成，其结果对该地区Ms≥5地震有较好的对应效果。再将前兆异常的信度视为时间和距离的函数，建立地震前兆异常综合信度的时空动态模型，并对1976年以来河北省及其邻近地区Ms≥5地震（不含唐山余震）进行检验，结果表明，地展均发生在前兆综合信度的高值区。对1979年7月9日江苏保阳6.0级地震和1985年4月18日云南禄劝6．3级地震进行检验，结果也较理想。
The reliability of earthquake precursory anomalies from 1980 to 1997 in Hebei Province and its adjacent areas was synthesized over time, and the result has better effect on Ms≥5 earthquakes in this area. Then, the reliability of precursor anomaly is regarded as a function of time and distance, and the spatio-temporal dynamic model of synthetic precocity anomaly of earthquake is established. The Ms≥5 earthquake (excluding Tangshan aftershocks) in Hebei Province and its adjacent areas since 1976 The results show that the land expo took place in the high value area of precursor comprehensive reliability. The test was conducted on the M 6.0 Ms 6.0 earthquake of July 9, 1979 in Jiangsu Province and the 6.3 earthquake in Luquan, Yunnan Province, on April 18, 1985, with satisfactory results.
