摘要
利用 Grad 求矩法,求解了考虑多体效应的量子等离子体动力学方程,给出了输运方程的一般形式,作为例子计算了氢等离子体的电导率和热导率.结果表明:新动力学方程包括动屏蔽和静异蔽两重效应,静屏蔽效果正好与过去考虑德拜屏蔽一致.动屏蔽效应,当系统离平衡态不远时,修正较小.
Neokinetic equation of plasma is solved by means of Grad moment method. General forms of transport equations are found.For example,electrical conduc- tivity and thermal conductivity are calculated in hydrogen plasma.It is shown that static shielding and dynamical shielding are involved in Neokinetic equation. Static shielding effect is as Debye shielding.The influence of dynamical shielding effect is very small when system is near equilibrated state.
