一个类似于儿童玩具的沙堆崩坍模型是一种可用于研究如何使核聚变装置托卡马克 (Ｔｏｋａｍａｋ)达到最佳条件的工具 ,托卡马克是一种利用核聚变反应来获取能量的装置 .为了能实现获取能量这个目的 ,第一步是要在托卡马克装置中得到高温、高密度的等离子体 ,特别是一种称为Ｈ - A sand-pile collapse model, similar to a children’s toy, is a tool that can be used to study how best to achieve optimal conditions for the Tokamak nuclear fusion device, a device that uses nuclear fusion to extract energy. In order to achieve this goal of energy harvesting, the first step is to get a high-temperature, high-density plasma in a Tokamak device, especially one called H-
