提出了用“子群”概念处理稳定分子流温度非平衡态问题的想法。在球形容器,各向同性气源的情况下说明了运用这一概念的方法。在这种情况下,“次束”分子密度是均匀的,但却具有非麦克斯韦的速度分布,它可用一等效温度的麦氏分布近似,等效温度是气体分子适应系数,粘着几率等参数的函数。 The idea of ​​using the concept of “subgroups” to deal with the temperature non-equilibrium state of molecular flow is proposed. In the case of spherical vessels, isotropic gas sources illustrate the use of this concept. In this case, the “bundle” molecular density is uniform, but with non-Maxwell velocity distribution, which can be approximated by an equivalent temperature McNamara distribution. The equivalent temperature is the parameter of gas molecular adaptation and adhesion probability The function.
