普朗特边界层方程和纳维? ?斯托克斯方程相比，有了重大的简化。 - In this paper i has applied inverse operator method to the solution of the nonlinear boundary layer equation on base of the former knowledge , and have gotten the approximate analytic solution
本文把逆算符方法应用到了普朗特边界层方程上来，并且求出了逼近解析解。 - The creative points of the thesis are as follows : （ 1 ） the thesis establishes turbulence boundary layer equation that contains centrifugal force in flow field of two - dimension boundary layer of centrifugal pump and gives its solution
本文创新之处是： （ 1 ）在离心泵叶轮二维边界层流场内，建立了包含离心力的湍流边界层方程并给出了近似解。 - But on the other hand , should also see , boundary layer equation as before is a nonlinear differential equation set of two steps , the nonlinear nature of equation is still retained , so solving this system of equations on mathematics untie is fairly difficult
但另一方面也应看到，边界层方程依旧是一个二阶的非线性偏微分方程组，方程的非线性的性质仍然保留，这使得在数学上求它的解还是相当困难的。
