摘　　要：本文运用量级分析和渐进展开匹配方法推导了适用于旋转系统流动分离的渐进结构方程，此方程具有三层结构的特点，每层有不同的流动性质，层与层之间通过匹配关系联系起来，旋转效应在渐进结构中不出现。由于层间参数的传递反映了该方程及其定解条件的椭圆型特征，加之三层区域的精细结构，该方程为激波／边界层干扰的计算提供了手段。Based upon the order of magnitude analysis and asymptotic expansion matched method, this paper develops the asymptotic structure equation applied for flow separation in rotating system. This equation embodies feature of triple-deck structure. There is different flow na ture in each array, which is connected by matched relation. The rotating effect doesn't appear in the equation. Because the transfer of parameter of between array reflects characteristics of elliptic equation of the equation and its definitive solution condition, in addition the fine structure triple deck field, the equation provides approach for ioteraction of shock/boundary layer calculation.
