| 摘 要： | 从1953年Danckwerts提出离集的概念到现在，微观混合研究已有50多年的历史．所谓微观混合是指分子尺度上的均匀化过程，即通过破碎和变形使未混合的液体微元尺度减小，再由分子扩散达到最后混合．由于缺乏足够的分辨率，以物理现象为基础的方法难以满足微观混合研究的需要，因此采用化学反应作为分子探头的化学方法就成了目前最常用的研究微观混合的方法．这些反应可以分为3类：

| Abstract: | During the preparation of the iodide-iodate solution I- was oxidized,which caused large deviation of calculated segregation index from experimental value.In this paper, the concentrations of I-3,I- and I2 in as-prepared solution were determined through concentration analysis of I-3 by spectrophotometer, and then the oxidized amount of I- was calculated.A modified expression of segregation index for iodide-iodate reaction system was deduced and verified by experiments, indicating that the deviation between experimental results and the modified expression was within ±15%. |
