摘　　要：对于高速轿车风沙流边界层动量积分,在确定的边界条件的控制下,采用四次多项式结构来近似边界层内的速度分布,获得含有固相对边界层扰动因素的形状因子。通过对动量积分的相关变换和对因子函数的讨论及其对曲线的分析,在引用了边界层厚度系数的条件下,得到风沙流边界层方程的解的表达式并给出其边界层计算的有限次逼近算法。通过对边界层方程的解的分析,确定了解的存在性和唯一性。For momentum integral of wind sand fluid boundary layer of high speed car, in the control of certain boundary conditions, quartic polynomial construction is used to approximate rate distribution in boundary layer and curve factor having solid phase disturbance element is required. Also, by the relative transition of momentum integral, discussion of factor function and analysis of curve, in the condition of boundary layer thickness coefficient cited, solution expression of wind sand fluid boundary layer equation is obtained and the finite approximation algorithm to boundary layer calculation is given. In the end, according to the analysis of the solution, the presence and sole characters are determined.
