| Abstract: | This paper suggests three methods of fitting geomanetic diurnal variation, based on the data of geomagnetic diurnal variation obtained by three days surveying in four survey stations in shahe, Dongying, Zhengdi-ing.Shahgqiu. Non-isostatic effection of time-difference to the curves of geomagnetic diurnal variation was discovered.Through analysing the diurnal variation curves, we found that the diurnal variation in Dongying is obviously influenced by coase effection. |

| Keywords: | fit non-isostasy time-difference coast effection |
