| 摘 要： | 系统整理河北省1992-2014年流动重力资料，利用LGADJ数据处理软件，对每期重力数据进行单期平差、多期整体平差计算，改正历史遗留问题，利用差分结果绘制145幅流动重力等值线差分图，通过具体异常点位及重力变化分析，得出：①地震前重力场变化强度与震级大小存在相关性；②流动重力观测资料地震前具有较为明显的前兆异常反应；③地震均发生在重力变化的“0”等值线附近地区。

| Abstract: | Preliminary system of finishing the Hebei area in 1992-2014 mobile gravity data, using LGADJ data processing software, multi period overall adjustment calculation of each data and correct problems left over by history, drawing 145 pieces of isolines differential graph from the year 1992 to 2014, through analysis of specific anomaly and gravity changes:there was a correlation between the size of gravity field before the changes of intensity and magnitude of earthquake; mobile gravity observation data has obvious precursory anomalies reaction; earthquakes occurred in the vicinity of the gravity changes of "0" contour. |

| Keywords: | mobile gravity anomaly measurement network “0”contour map gravity timing diagram |
