摘要
本文用自组织临界性理论的观点探索非均匀沙与均匀沙之间本质的区别．首先介绍了自组织临界状态理论的基本概念；然后叙述了水槽实验的过程，证明了水下非均匀沙属于自组织临界性系统的可能性；最后，基于自组织临界性系统的标度律。
From the view point of self organized criticality, this paper investigates an essential distinction between non uniform sands and uniform sands. First, the concept of self organized criticality is introduced. Then, the process of flume experiment is described, from which the possibility of non\|uniform sediment in water being a self organized critical system is demonstrated. Finally, based on the scaling law the critical area ratio of covered river bed to form a stable armoring layer is deduced with renormalization group theory.\=
