High acceleration and complex grain can both cause particles to aggregate highly in local part of SRM, thus form high-temperature and dense two-phase flow.
高过载或复杂装药都会引起凝相颗粒在固体发动机局部高度聚集，形成高温稠密两相流。
2
Uniform Design Method was applied to study the quantitative relationship between optimally dense situation and coarse aggregate composition.
利用均匀设计方法研究了最佳密实状态与粗集料组成之间的定量关系。
3
Coarse aggregate quantity can be identified by the dense test of the mixture.
