中文摘要：

对中国大陆构造环境监测网络（简称“陆态网络”）连续重力台站记录的于田Ms7．3级地震震前8d连续重力资料进行分析，分别于震前6d和2d在中国大陆不同区域发现了周期为4—8s的重力扰动信号。前者信号强度从鹤岗台经太原-银川台向西至库尔勒台逐渐减弱，形成一个条带；后者信号强度从温州一厦门台向西至襄樊．万州台逐渐减弱，形成一个区域。本研究对全面认识震前扰动现象、揭示其产生机理具有重要意义。

英文摘要：

Analysis of continuous 8 days gravity data of Crustal Movement Observation Network of China （CMONOC） before Yutian Ms7.3 earthquake on Feburaryl2,2014 indicated that the gravity disturbance signals with the period of 4 - 8 seconds appeared 6days and 2days before the Earthquake and formed 2 belts. The first one is Hegang-Taiyuan-Yinchuan-Korla, the second one is Wenzhou-Xiamen-Xiangfan-Wanzhou. The phenomenon is significant to comprehensively understanding the disturbance before the earthquake and its mechanism.
