摘　　要：虚拟实验模型辅助化工实验教学,是解决化工实验教学内容多、课时少问题的有效途径。利用Excel的绘图功能与VBA混合编程,实现了实验虚拟模型的动画效果,获得即时实验模拟数据,完成停留时间分布测定的动态模拟,是一种新的计算机仿真解决方案。当实验用时超过数学期望理论值的5倍时,其相对误差在4%以内,结果较为理想。采用这类虚拟实验模型适合于化工实验辅助教学。Virtual experiment model is a useful way to resolve the questions of more contents and less lessons for the chemical engineering experiment.This paper is intended to use the Excel＇s powerful plot function and the mixed VBA programming,realize the animation effects of the virtual experiment model,obtain the real-time simulation data,and then complete determination of the residence time distribution of dynamic simulation.The model provides a new solution for the computer simulation.It was found that when the experiment time exceeds more than 5 times of the mathematical expected value,the relative error is less than 4%.This end result is more desirable.This experimental model is suitable to help the chemical engineering experiment teaching.
