摘要
通过对新疆ＤＳＪ型水平断层活动测量仪观测资料进行分析，发现它们具有共同的年周期变化规律。这种年周期变化主要是由水平断层仪所跨岩体的热胀冷缩造成。采用“动态灰箱模型”可消除这种因温度而造成的年周期变化，从而突出地震前兆异常。
Through analysing the data observed by type DJS fault crossing levellers in Xinjiang, it is found that they have the same annual variation, and this kind of variation is caused by the heat expansion and cooling shrinkage of the rock the levellers cross. Using “dynamic grey box model ”can eliminate it, thus making seismic anomaly conspicuous, and providing reliable base for earthquake prediction.
