南京台地电场观测因地铁干扰择址重建。考虑到地电场的矢量特性，取消斜道观测，布设同方向3个测道的多极距地电场观测系统。《中国地震前兆台网数据处理系统》只是针对传统的“L”型地电场布极方式而开发的数据处理软件，不能对南京台地电场数据完全有效的进行处理，在中国局三结合课题（201116）的支持下开发了《多极距地电场观测系统数据处理软件》。

Because of observation interference of subway, electric field of Nanjing Seismic Station has reconstructed. Considering the characteristics of vector, cancelling the ramps observation, we have built observation system for multi-polar distance of three ways in the same direction. 《The China earthquake precursory network data processing system》 only for the traditional "L" type, that can't to deal with the data of multi-polar distance completely. Under the support of China bureau three combination subject (201116) we have developed 《electric field processing software to electric field of multi-polar distance》.
