颗粒流体系统的主要特征在于其非均匀的时空动态结构及其随操作条件改变出现的突变行为.由于非线性非平衡系统不存在普适的稳定性判据,因此,寻求非线性颗粒流体系统自身特定的稳定性条件及其变化规律是实现这一系统定量化的关键.垂直并流向上的颗粒流体系统随流体对颗粒控制能力的增加,可依次出现颗粒控制 Particle fluid system is characterized by its non-uniform spatial and temporal dynamic structure and its mutation behavior with the change of operating conditions.Because there is no universal stability criterion for the nonlinear unbalanced system, the nonlinear particle fluid system itself The specific stability conditions and their changing rules are the keys to realize the quantification of this system.With the increase of the control ability of the fluid on the particles, the particle flow system with vertical and upward flow can appear particle control
