对应计算流体力学基础及应用中第8章中的例子，有助于读者学习超声速外略平板流动中流场的分布，为深入学习计算流体力学打下坚实的基础(Corresponding to the basis of computational fluid dynamics and the examples in the eighth chapter, it will help readers to study the flow field distribution in supersonic flow in a slightly flat plate, and lay a solid foundation for further study of computational fluid dynamics)
