中文摘要：

在这份报纸，黄土的微观结构上的量的学习在 1995 基于 Yongdeng Ms5.8 地震的地震沉淀的学习被做。用 SEM 和图象处理技术，黄土的微观结构上的比较分析被做，黄土毛孔的分发曲线被获得。在地震效果下面基于激光谷物分析器测试和架子结构变化，黄土的动态性质被解释。同时，从地震地区和非地震的地区的黄土的毛孔分发是不同 meizoseismal 地区的毛孔分发特征是不同的 compared.The 结果表演，并且在类似的深度 bas 弄平那黄土实质的差别也。

英文摘要：

In this paper, quantitative study on the microstructure of loess is done based on the study of seismic subsidences of the Yongdeng Ms5.8 earthquake in 1995. Using SEM and image processing techniques, a comparison analysis on the microstructure of loess is done and distribution curves of loess pores are obtained. Based on laser grain analyzer test and trellis structure changes under earthquake effect, the dynamic properties of loess are explained. At the same time, pore distribution of loess from seismic zone and non-seismic zone is compared. The result shows that the pore distribution features of different meizoseismal zones are different, and even that loess at the similar depths has substantial differences, too.
