摘　　要：本文提出了系统弱相互作用下,近平衡态系统的Boltzmann方程的驰豫近似方法,推证了近平衡态的Boltzmann方程的驰豫近似公式。This paper gave the relaxation approximation method of the boltzmann equation near equilibrium states system under the weak interaction, introduced the relaxation aproximation formula of Boltzmann equation near equilibrium states system, and cultivate the conductivity of the weak electric field and the inter diffusion coefficient of the binary component gas.
