| 摘 要： | 介绍了地磁场空间线性相关的计算方法。详细阐述了利用此方法在预报武定地震 (1 995年 1 0月 2 4日 ,MS6.5)及丽江地震 (1 996年 2月 3日 MS7.0 )中的应用。笔者对此方法进行了理论推导 ,结果表明相关参量与台站经纬度的选择有关 ,而地磁场的空间线性相关的规律与台站的经纬度选择无关。该结果对台组的选择起到了指导作用

| Abstract: | In this paper,the calculation method ofthe space linearcorrelation ofthe geomagnet- ic field,and the statistic test and the error analysis have been introduced.This method was applied in predicting the Wuding earthquake with ( MS=6.5,on Oct.2 4 ,1 995) ,and Lijiang earthquake with( MS=7.0 on Feb.3,1 996) .The prediction was praised by the State Seismological Bureau.The theoretical deduction of this method has been made by the author.The resultindicates thatthe correlation parameter is related with the selection of the longitude and the latitude of the stations,while the law of the space linear correla- tion of the geomagnetic field is notrelated with the selection of the longitude and the lati- tude of stations.This resultcan be used to direct the selection of the stations. |
