Various influence factors of solid boundaries on discontinuuties in the gas molecular distribution function are considered and a bimodal two-stream relaxing distribution is suggested. In applying it to the heat conduction problem between two parallel plates by Maxwell transport equation we obtained a closed solution.

Various influence factors of solid boundaries on discontinuuties in the gas molecular distribution function are considered and a bimodal two-stream relaxing distribution is suggested. In applying it to the heat conduction problem between two parallel plates by Maxwell transport equation we obtained a closed solution. According to the theory suggested in this paper, in the linear case, the calculated heat transfer is close to that given by existing theory. In the nonlinear case (when the temperature ratio of two plates is equal to four), the difference between Willis precise numerical results and ours is less than 2.5%. This is an obvious improvement as compared with the Liu-Lees theory. Furthermore, temperature calculations demonstrate the existence of a Knudsen layer.

分析了固体边界对分子分布函数不连续性的各种影响因素;提出了双峰二向流弛豫分布,将它应用于麦克斯韦输运方程以研究二平行平板间的热传导,得到了封闭解.根据本文提出的理论,在线性情况,计算得到的热流值与现有的理论结果相近;在非线性情况(两壁温度比为4),与Willis的精确数值结果相差小于2.5%.这与具有代表性的Liu-Lees的理论结果相比有较大改进.此外,温度分布计算显示出了Knudsen层的存在.

In this paper, a generalized dispersion relation of plasma is btained from MHD equation, taking account of the relative velocity VD between electrons and ions. The dispersion relation is analyzed approximately.

本文从磁流体方程组出发,在考虑到电子与离子间具有相对运动的情况下,导出了等离子体中的电磁双流不稳定性所满足的色散关系。先在简化的条件下进行了分析和研究,后对电磁双流不稳定性的色散关系进行了定量计算。结果表明,随着夹角θ的增加,不稳定性的激发条件亦相应地变得苛刻。

The classical plasma theory, two-stream instability theory and magnetic enhancement effect have been used to calculate the range and deposition power of an intense relativistic electron beam in the target matter. It is recognized that anomalous absorption is the major energy absorption mechanism for an intense relativistic electron in the target matter. With the two-stream instability and magnetic enhancement effect taken into account, experimental results can be interpreted rather well....
