微观混和一般指物料从湍流分散后的最小微团（Ｋｏｌｍｏｇｏｒｏｖ尺度）到分子尺度上的均匀化过程。这种小尺度的均匀化过程对于快速复杂反应有着重要影响。４０年来对微观混和进行了不少的研究，近十多年来机理研究才取得了长足的进展。本文将对这个领域中有关概念和模型的历史发展、形成的主要学派以及当前的研究状况作一全面的介绍。 Micro-mixing generally refers to the material from the smallest turbulence dispersed micelles (Kolmogorov scale) to the molecular scale homogenization process. This small-scale homogenization process has a significant impact on rapid and complex reactions. In the past 40 years, a great deal of research has been done on the micro-mixing, and only a great progress has been made in the mechanism research over the past decade or so. This article will give a comprehensive introduction to the historical development of the concepts and models in this field, the main schools formed and the current research situation.
