摘　　要：对于器内物料微团的流动处于理想混合状态的单个或多个CSTR组成的反应系统,物料微团流出反应系统的状况具有统计特征,用示踪剂模拟物料微团在反应系统中流动特性是常用的方法。由于示踪剂微团数目和单位时间中的时间微元数目均符合大数定理,单个示踪剂微团的流出反应系统成为随机概率的统计问题。利用Excel表格、函数功能及VBA混合编程,克服了其他编程软件对处理模拟数据不太尽如人意的缺点,与理论推导十分接近的模拟了CSTR反应系统内物料的流动状况,为探索和揭示各类反应器流动特性提供了一种有效解决途径。Micelle flowing inside the material is ideally mixed CSTR single or multiple reaction system, and the status of the outflow of material micelle reaction system has the statistical characteristics of the flowing of tracer analog materials micelles in the reaction system,which is commonly used method. Tracers the number of micelles per unit time in the number of element is in line with the law of large numbers, a single tracer parcels in out of the reaction system to a random probability statistics. By using Excel tables, functions, features and VBA hybrid programming, they overcome the shortcomings of the other programming software to deal with the simulation data that is less satisfactory, and are very close to the simulation with the theoretical flow conditions of the material in the CSTR reactor system, in order to explore and reveal each class reactor flow characteristics and provides an effective solution.
