The random mathematical model is described using equivalent markov equations . the time and state parameters are discrete . based on the model , the flow rate distributions along radial and average at any height can be calculated directly , moreover , the probability transition matrix of the flow can be determined via the statistic character of the random cumulate particles , and be corrected by s . cd the random theoretical model shown in fig . l , the section of the bed of tbr is divided into a series of concentric circles 一、在常温和常压下进行滴流床反应器流率分布的研究，以状态离散、时间离散的齐次markov过程描述了滴流床在滴流区的流率分布，建立了滴流床在滴流区流率分布的随机模型，根据此模型可以： 1 、可直接确定任一高度下的液体径向流率分布及平衡流率分布； 2 、液体流动的概率转移矩阵可由随机堆积颗粒的统计特性确定，以参数s修正。
