【摘要】 建立了小波分解模型,应用该模型将宁夏红果子形变台及苏峪口形变台短水准观测资料中的不同周期成分进行了有效分离。分离后的3阶近似及3阶细节部分所显示的异常变化能够更直观和显著地对应宁夏及周边地区发生的地震。更多还原

【Abstract】 A wavelet decomposing model has been established in the paper, by which the components with different periods in the short leveling data observed at the Hongguozi and Suyukou stations of Ningxia are effectively separated. The anomalous variation indicated by the 3 order approximation and the 3 order specific details after the decomposition can more directly correspond to the earthquakes occurred in Ningxia and vicinity.更多还原
