摘要 在已得到单纯气体Boltzmann方程的正规解情况下,进一步讨论了混合气体的情况.对具有小Knudsen数的Boltzmann方程组进行Fourier变换.再选取适当的条件避免正规解中的久期项. Based on obtaining a normal solution of the Boltzmann equation for a simple gas,the solutions for a gas-mixture are discussed.The equations with a small Knudsen number are transformed by the Fourier transformation.The secular terms in the normal solution may be removed under a suitable condition.
