| 摘 要： | 重力固体潮观测资料中的零漂项，从整体上看，在缓慢地变化着，本文以朔望月的一半作为时间长工，分段对零漂进行线性模拟，之后，再进一步消除长周期潮汐波对零漂的影响，提出了零漂的变化，这是一种低频非潮汐信息，它负载于零漂之上，可能含有地震前兆。

| Abstract: | The zero drift term in observation data of gravity earth tide, on the whole, is in slow change. In this paper taking a half of lunar month as time length, the values of the zero drift are simulated linearly and piecewice.And then effect of long period tide wave on the zero drift is eliminated and the variation of the zero drift is drawn. This is a low frequency non-tide information which is carried on the zero drift and may contain earthquake precusor. |
