| 摘 要： | 基于Ｂｕｂｂｌｅ函数构造小波基，用Ｍａｌｌａｔ塔式快速算法对地震信号进行二维多分辨分析，并利用局部极值理论提取、检测反射同相轴及断层。理论和计算结果均表明，该方法能够检测出不同尺度下的地震信号突变特征，且具有一定的抑制噪声能力。

| Abstract: | Based on the Bubble function, the seismic signal was analyzed in two dimensions by Mallat algorithm. The reflected in phase axis and fault were detected and extracted using local extreme value theory. The result shows that the method can detect a sudden change of seismic signal in different levels and reduce noise effectively. |
