摘　　要：通过对调制比预报地震方法进行改进 ,并使用改进后的地震调制比 Rm10 对华北地区进行空间扫描。结果表明 ,中强地震前 1～ 3年 ,未来震中周围通常出现 Rm10 中期异常区 。The prediction method of seismic modulating ratio is proved in this paper. The seismicity data are used to space scanning in North China by use of the proven method of seismic modulating ratio Rm10. The result shows that in mid term about 1～3 years before most strong earthquakes there are obviously anomaly zones of Rm10 in the neighborhood of epicenter in general. This method has very good effects in mid term earthquake prediciton.
