摘　　要：本文在平面截面的假定下,以幂次自模拟解为基础,提出了高超音速气流绕一般细长(辶回)转体流动的普遍线性化理论.问题最后归结为积分一组与具体问题无关的常微分方程组.这些积分可以事先算出,制成表格,当要解各种具体问题时,只需查表和进行一定的代数运算,即可将流场全部参数算出.On the basis of a self-similar solution as well as of the assumption, of the 'Transverse Motion', a general linear theory on hypersonic flow over a general slender body is set up in this paper. By means of this theory, the problem concerned can be put into a universal system of O. D. Eqs. which can be integrated numerically in advance.
