The innovation of our rearch:(1) A new one-dimensional sandpile model is set up, in this model avalanche probability is introduced.(2) Emulational simulation is performed with cellular automata method, and numerical analyse is carried out according the simulation result.(3) With the simulation result, We not only explained the SOC phenomena appearing in real sandpile, but also revealed a new path to SOC.

本文的创新之处在于：建立了一个含崩塌概率的一维沙堆模型；用元胞自动机的方法对模型进行了仿真模拟，并对仿真结果进行了数值分析；我们的模拟结果不仅很好地解释了真实沙堆中出现的自组织临界现象，而且揭示了一条通往自组织临界性的新途径。

They are the effect of boundary restriction on the granular flow, the bulk elasticity of granular assemble and the effect of horizontal vibration on the sandpile avalanche.

本论文通过实验和计算机模拟的方法研究了颗粒物质流动和静态的几个问题，主要包括三个方面：外界约束对颗粒流状态的影响，颗粒系统整体的弹性和水平扰动对崩塌的作用。

A classical one dimensional sandpile model was researched in this paper, the model can not explain the self-organized criticality phenomena which appearing in one dimensional rice pile, so we did some mend on this model and make it including avalanche probability, with the new model we explained the SOC phenomena appearing in one dimensional grain pile.

本文考查了一个经典的一维BTW沙堆模型，发现它不能描述实验中已观察到的一维米粒堆的自组织临界现象，因此本文对经典一维BTW模型进行了改进，建立了一个含崩塌概率的一维沙堆模型，并用该模型解释一维米粒堆中出现的自组织临界现象。

通过研究如何用沙堆模型来描述电力系统的自组织临界性，提出了先建立各网省局等规模稍小电网的实时动态沙堆模型从而形成一个沙堆群的模型来模拟整个全国电网的设想。

He even produces his own version of Malcolm Gladwell's "tipping point" in the form of "the sandpile"(one of his experts suggests that "after an initial period, in which the sand piled itself into a little cone, the stack would organise itself into instability, a state in which adding just a single grain of sand could trigger a large avalanche…").

书中一位专家称："在经历了沙粒汇聚构成小锥的初始阶段后，沙堆将会向不稳定状态构建自身，在那种状态下，添加哪怕一粒沙子都将引发大规模崩塌。"
