摘要
沙堆模型是自组织临界状态理论的范例。介绍一种倾斜平面下半无限松散边坡坍塌沙堆模型实验研究 ,实验结果表明 :沙堆的自组织临界性与颗粒的非均匀性有关 ,从而首次用实验方法证明了自组织临界状态受系统组织原则影响的猜测。
WT5BZ]: The sand pile model can serve as a paradigm for self organized criticality. This paper reports an experimental study on the sand pile model with semi boundless collapsed loose slope under inclined plane. Experimental results indicate that the self organized criticality of a sand pile is related to the granular non uniformity, which for the first time experimentally proves the influence of organization principles of the system on the phenomenon of self organized criticality.
