| 摘 要： | 地震波在粘弹性介质中传播的一个基本特征是能量的衰减及地震波的瞬时波形变化。从广义上说，衰减可分为两类：一类是与地震波传播特性有关的衰减|另一类是反映介质内在属性的地层本征衰减，地层的本征衰减通常用品质因子来度量。反演品质因子的方法有多种，常用的是谱模拟频谱比法。笔者的主要目的是通过模型试算来分析评价该方法在反演品质因子时对干涉和噪声的稳定性，得出有益的结论，用于指导反演计算。

| Abstract: | The essential feature of the seismic wave propagation in viscous elastic media is the attenuation of its energy. Generally speaking, the attenuation can be classified into two categories, one is related to the seismic wave propagation, and the other is related to the characteristics of the strata. One of the most important parameters that scale the degree of attenuation is Q factor. This paper discusses the stability of spectral analog spectrum ratio method to interference and noise. |
