Two-phase flow is a complex multivariable random process.
两相流的流动是一个复杂的多变量随机过程。
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。
For the complex characters of two-phase flow, it's really difficult to accurately measure those flow parameters.
但由于流体流动特性的复杂多变，使得两相流参数检测难度较大。
