粒状气体的实验不仅提供了多粒子系统经历随机耗散相互作用的统计信息，它们也可能有助于测试数值模拟的预测，并获得稀粒状物质的自组织集群和稳定的组件的理解。我们简单地回顾一下零重力条件下在不同平台上的实验。分析了探空火箭飞行、抛物线飞行和落塔射击的实现。我们评估一般的实验要求，判断不同平台的适当性，并提出定量结果。(C)2015年空间研委会。由爱思唯尔有限公司出版。保留所有权利。
Experiments with granular gases do not only provide statistical information on multi-particle systems undergoing random dissipative interactions, they may also help to test predictions of numerical simulations and to gain understanding of the self-organization of dilute granular matter to clusters and stable assemblies. We shortly review an experiment under zero gravity conditions on different platforms. Implementations on a sounding rocket flight, parabolic flights and drop tower shots are analyzed. We evaluate general experimental requirements, judge the appropriateness of the different platforms, and present quantitative results. (C) 2015 COSPAR. Published by Elsevier Ltd. All rights reserved.
