【摘要】 本文对中国西部地区二十多年的地壳垂直形变场演化特征进行了分析，提取了地壳垂直形变场的形变速率波中的０阶子波，发现：地震的发生大多在地壳波浪的０阶子波的０振幅线与断裂相交的地带附近。认为：形变速度波的０阶子波的传播是地震破裂的扰动力源，它的０振幅线与构造断裂的交汇部位可作为地震触发的重点监测区。更多还原

【Abstract】 The peper analysed the crushal vetical deformation field Characters in the west6rn China over twenty years,picked up zero order wavelet from the deformation velocity waves in the crustal vetical defor mation fields,and found out that the earthqtiakes often occurred near the junction area of the zero amplitude line and the fault zones.The authors thought that zero cider wave’s propagation of the deformatin velocity waves was the disturbance force source of the earthquake rupture,the junction area ofthe zero amplitude line and the tectonic faults was earthquake monitoring area.更多还原
