摘要
文中给出汽车运动空气流场变分泛函的严格互补极点——鞍点定理,并且证明变分解存在唯一。为汽车空气形状阻力有限元解奠定了理论基础。
The paper presents a vigorous complementary extreme——a sadlepoint theorem and proves that the existence of variational solution is unique.Thereby the author lays a theoretical foundation for the solution of autoairform resistence by the finite element method.
