本文对一颗大质量（M= 20 M）星星的球对称包层进行了自洽计算，其包层在连续辐射压的作用下向外流动。得到了描述任意光学厚度、电离度和不透明度κ的外流方程组。在常数κ和电离度为常数的情况下，通过奇点积分和中间区域的光滑拼接得到了数值解.在音速点和无穷远奇点附近找到了渐近解。
The article presents self-consistent computations of the spherically symmetric envelope of a massive (M=20M⊙) star whose envelope is flowing outward under the action of continuum radiation pressure. A system of equations describing the out flow for arbitrary optical depth, degree of ionization, and opacity κ are obtained. A numerical solution is obtained for the case of constant κ and degree of ionization via approaching integrations from the singularities and smooth joining in the intermediate region. Asymptotic solutions are found in the vicinity of the sonic point and the singularity at infinity.
