简要介绍地震事件震源倒谱分析的基本原理和方法,分析发生在朝鲜半岛的2006年核爆炸（ML 4.3）与2007年ML 5.1地震事件的倒谱特征。结果表明，倒谱判据在朝鲜半岛具有判识效能。

Basic principal and method of seismic source cepstrum analysis are introduced.  Source cepstrum characteristics of the 2006 explosion ML 43 and 2007 ML 5.1 earthquake in Korea peninsula are analyzed. The result indicates that the two events with different source type can be well distinguished by using the cepstrum criterion.
