【摘要】 本文从介绍白家疃台站的 Geodynamics TRG—1型潮汐重力仪数字化重力固体潮观测系统入手，对所记录到的1999.6～2002.6期间的重力变化及其与地震的关系进行了讨论．认为这一长达3年、变化幅度为130×10^-8m·S^-2的重力变化可能是2001年11月14日昆仑山口西8.1级地震的远场前兆异常．更多还原

【Abstract】 The gravity earth—tide observation system including Geodynamics TRG-1 type gravimeter and digital datacollection system is introduced in this paper.The gravity variation data during 1997～2003 observed at Beijing Baijiat-uan station equipped with gravimeter of Geodynamics TRG-1 # 804 are analyzed.The results show that the gravityvaried rapidly with the amplitude of 130×10^-8m·s^-2 in the three years from June 1999 to June 2002.This may becaused by M 8.1 earthquake occurred at West Kunlun Mountain on Nov.14,2001.更多还原
