利用倒谱辅助识别终止相——以9·21集集地震为例

Using cepstrum to discrimination the stopping phase——A case study on Jiji 9 ? 21 earthquake

应用倒谱对终止相识别的理论依据,根据厦门地震遥测中心记录的9·21集集地震进行实例分析,认为倒谱分析可以辅助识别终止相,结合传统的终止相走时特征和动力学特征识别方法,进而提高终止相识别的准确度。

In this article the author introduced the theory of cepstrum in detail,then pointed out the inner connection with stopping phase, and process the data of Jiji earthquake with the cepstrum. The processed result indicated that this new method is good assistant to discrimination of stopping phase and has good prospect on application.
