- 摘要:
- 从数学、几何及物理方面,简要介绍了地震事件震源倒谱分析和震源性质判别的基本原理和方法。将该方法应用于小震级的地震与爆炸事件的分析,结果表明，朝鲜半岛6次较小地震与爆炸的震源倒谱具有显著的峰值差异，倒谱差异的定量描述C值参量分别大于和小于1。
In this paper, the basic principles and methods of determining seismic source characteristics and of analyzing seismic source cepstrum are described from the aspects of mathematics, geometry and physical dimensions. The method has been applied to the small earthquake and explosion analysis. The results showed that the cepstrum of 6 times small earthquake at Korea Peninsula have significant difference to that of explosion in the peak. The quantitative parameters C of the cepstrum is great than 1 when it is an earthquake or less than 1 when it is explosion.
