GS-15型重力仪记录畸变特征分析
|
摘要
通过对成都地震台GS-15型重力仪记录固体潮曲线畸变特征分析,找出记录曲线畸变的变化规律,并对引起该变化的因素、物理机制进行分析。仪器加温系统供电电源性能变差,导致仪器内部恒温系统破坏是引起记录固体潮曲线畸变原因。
Through the analysis on the aberrance of solid tide that recorded by GS-15 gravimeter at Chengdu Seismic Station,we found aberration law,and made a study on influencing factors and physical mechanisms.The reason that leads to the solid tide record curve distorted was that the performance of heating power becomes poor,damage the temperature system inside and outside the instrument.
