摘　　要：在地磁绝对观测预报地震中,若充分利用地磁场一般具有有规则的等交线分布这一特征,可以使原来仅限于小台距的差值预报法推广到大台距,并在实践中获得了较理想的结果.这样,解决了台站稀少地区台站观测资料难以用于地震预报的难题,为地磁绝对观测预报地震找到了一种新的途径.The difference presiction can be used to larger stationn - to - station distance , which is usually used to small distance, if the characteristics are used in earthquake prediction with geomagnetic absolute observation in which the distribution of variation contour in the geomagnetic field is in some regularity, which has gained good results in practice. Thus the difficult problem is settled that the station is sparse and the regional data can be used in earthquake prediction. which provides a new way for the earthquake predietion with geomagnetic absolute observation.
