用奇异扰动方法讨论了具有小Knudsen数的Boltzmann方程的边界层解,并把它归结为求解联立代数方程的问题。对于Maxwell边界条件,还得到了温度间断系数对于边界上的调节系数的依赖关系。The "boundary layer" solution of Boltzmann equation with a small Knudson number is discussed by using a kind of singular perturbation method, and is reduced to solving a set of linear algebraic equations. The dependence of the temperature jump coefficient on the accommodation coefficient is obtained for the Maxwell's boundary conditions.
