【摘要】 用华东地区十年地震资料和迭代方法，在华东走时表的基础上，计算出百余地震台站的作为距离的函数的走时偏差值。将这些结果当做台站校正值用于地震定位，定位精度得到明显提高。更多还原

【Abstract】 On the basis of the East China travel time model,using the logical seismic data ofall stations in the East China for ten years,the travel time deviations of more than ahundred seismic stations have been computed by the method of iteration. By use of thesedeviation values as station corrections,the precision of hypocenter location is raised obvi-ously.更多还原
