...地震相关的研究得知，影响地震动之主因包括有震源规模、破裂过 程的震源效应(source effect)、地震波的传递路径效应(path effect)和场址效应(site effect)。然而地震灾害的严重往往与局部地区的场址效应息息相关，而场址效应 的大小则介于地下浅层的地质。

The path effect of seismic wave propagation (seismic attenuation) involves an important influential factor, the anelastic attenuation of medium, which is measured with quality factor Q, apart from geometric attenuation with the distance.
地震波传播的路径效应（地震波衰减）,除了随距离存在几何衰减外,还有一个重要的影响因素——即介质的非弹性衰减,用介质品质因子Q值来度量。
