自持磁约束电子云的流体理论(Ⅰ)流体方程组

THE FLUID THEORY OF SELF-SUSTAINING MAGNETICALLY CONFINED ELECTRON CLOUDS (I) FLUID EQUATIONS

本文利用流体理论研究轴对称自持磁约束电子云.这种电子云是依靠Penning放电维持的.在电子云中电子的运动特性可以用由连续性方程、动量方程、能量方程、Poisson方程和热传导方程组成的流体方程组来描述.文中还讨论了电子云中电子的扩散、逃逸和能量输运等问题.

In this paper the axisymmetrical self-sustaining magnetically confined electron clouds are studied by means of the fluid theory. In the electron clouds which supported by the Penning discharge the property of motion of electrons can be described by the fluid equations: continuity equation, momentum equation, energy equation, Poisson equation and heat transfer equation. The problems of the diffusion and escape of electrons and the energy transport in the electron clouds are discussed.
