摘　　要：研究了垂直气固上行流动系统的状态与空隙率的关系,指出当气固两相动能相等时,系统处于最稳定状态。此时颗粒集聚具有最大空隙率ε_(max)·根据上述原理推导出ε_(max)的表达式。将计算结果与Matsen等的结果进行了比较,表明本法合理,计算简单,物理意义明确。The relationship of system state with voidage has been studied in vertical gas-solid upflow system. Based on the basic idea of equal energy, an equation of the maximum voidage εmax was obtained. A comparison of the calculated results of this and Matsen's methods shows that this method is reasonable, simple and clear in physical conception.
