沙堆模型描述的L-模式中的等离子体湍流输运动力学的一些功能进行了扩展，通过添加适当的新的动力学，表现出增强约束模式的过渡。因此，通过改变适当的参数，可以获得具有和不具有边缘局域模（ELM）的H模。每一个展品的特点，让人想起什么是在约束等离子体观察。雪崩和扩散运输机制之间的相互作用是必不可少的，在这种情况下，系统显示周期性的边缘ELMing。
A sandpile model describing some of the features of plasma turbulent transport dynamics in the L-mode is extended, by adding appropriate new dynamics, to exhibit a transition to enhanced confinement modes. As a result, H-modes with and without edge localized modes (ELMs) can both be obtained by varying the appropriate parameters. Each exhibits features reminiscent of what is observed in confined plasmas. The interplay between an avalanche and a diffusive transport mechanism is shown to be essential, in this context, for the system to display periodic edge ELMing.
