摘要
提出以移位对数正态分布函数作为描述连续流动过程设备的停留时间分布的流动模型． 用本模型、扩散模型以及Ｇａｍｍａ模型对实验数据拟合结果的比较，表明本文提出的模型对于描 述各种程度的不对称停留时间分布曲线更具有适应性．
A model, in the form of the shifted lognormal distribution, is introduced for des- cribing the residence time distribution of flow equipment. Comparing the fitted results with two experiment data by this model, dispersion model and Gamma distribution model, it is shown that the model presented in the paper is more flexibility in discribing RTDS than the other two models.
