摘　　要：本文采用两层涡粘性模型和速度剖面的指数律,导出了可压缩动量矩方程的剪切积分解析表示式,从而大大简化了边界层计算。和其它理论结果相比,本结果更接近于实验数据。An analytical expression of shear stress integral for moment-of-momentum equation is derived by two-layer eddy viscosity turbulence model and the power law of the velocity profile. Thus the calculation of the compressible turbulent boundary layers is significantly simplified. The analytical expression is in good agreement with experimental data than other theoretical results
