摘　　要：利用黑龙江省七个大地电场台站11年数据,计算黑龙江地电台站渗流方位角,并尝试利用渗流方位角进行映震分析,通过对黑龙江省及邻区中强地震前的渗流方位角变化特征进行细致研究和总结,结果显示,地电场方位角异常与映震范围内的M>4.0以上地震有一定的对应关系,所以,对黑龙江地区开展渗流方位角变化特征分析具有一定意义。Based on the 11 years data of seven geoelectric stations in Heilongjiang Province,the seepage azimuths of Heilongjiang geoelectric station are calculated,and the seepage azimuths are tried to be used for seismic reflection analysis.Through careful study and summary of the variation characteristics of geoelectric field azimuths before moderate and strong earthquakes in Heilongjiang Province and its adjacent areas,the results show that there is one between the geoelectric field azimuths and the above earthquakes in the earthquake reflection range Therefore,it has certain significance to carry out the analysis of the change characteristics of seepage azimuth in Heilongjiang area.
