| 摘 要： | 使用张家口、怀来、赤城、宽城、易县和涉县6个地震台站共计43个观测项目的数字化资料，针对2002年至2005年山西地区发生的4次ML≥4．0地震，进行了地震前兆、同震反应及震后效应的系统研究。结果发现．河北省数字化资料对，1次山西4．0级以上地震前兆反应主要以应变为主，包括体应变和线应变，异常形态以固体潮畸变和抖动为主。 |

| Abstract: | Based on the digital data from 6 stations of Zhangjiakou, Huailai, Chicheng, Kuancheng, Yixian and Shexian, totally 43 observation items, the earthquake precursor, co-seismic response and effect after earthquakes are studied systematically for 4 ML≥ 4.0 earthquakes in Shanxi area from 2002 to 2005. The results indicate that the digital data of Hebei Province which responded to 4 times ML≥4 earthquakes in Shanxi is mainly deformation, including the body strain and linear strain. The anomaly shape is mainly, solid tide distortion and jitter. |
