颗粒聚集体的崩塌性质研究

The study on properties of the avalanches in granular assemblies

考察和分析了一般颗粒物质堆积体中崩塌的主要特征,概述了目前对颗粒物质崩塌研究所涉及的相关模型以及理论,并对其适用范围和局限性进行了分析,指出了他们的成功之处及不足,提出了对颗粒物质堆积体崩塌机理进行深入研究的一些思路。

The paper reviews and analyzes the central characteristic of the avalanches in general granular assemblies, and shows us the related model and theory on the avalanches, indicating the applicable conditions and localization of the theory, then places the emphasis on their successful parties and specifies their difficulties in interpreting the real granular assemblies. Finally, some suggestions are put forward to solve the problem existing in the current theory.
