摘    要:本文采用渐近方法求解了不均匀冷等离子体的修正电容器模型方程(非线性)。Dawson仅给出了一个波碎条件,但应用于不均匀等离子体时是不完备的。本文补充了使其完备化的第二个波碎条件,并同时、唯一地确定了波碎位置与波碎时间,进而导出了热电子最大能量与局部电场振幅的计算公式。新公式的预言,尤其是波碎时间和热电子最大能量与实验符合很好。 关键词

COLD PLASMA WAVEBREAKING DUE TO RESONANCE ABSORPTION
GU BIAO.COLD PLASMA WAVEBREAKING DUE TO RESONANCE ABSORPTION[J].Acta Physica Sinica,1984,33(3):331-340.

Abstract:A nonlinear equation of the modified capacitor model has been solved by means of the Bogoliubov asymptotic method. Dawson only gave a wavebreaking condition which is not complete when it is applied to the inhomogeneous plasma. In this paper, the second wave-breaking condition has been added for completeness; thus the wavebreaking position and wavebreaking time can be uniquely determined simultaneously, and the formulas of the maximum energy of hot electrons and the localized electric field amplitude can also be obtained. The agreement between the theoretical predictions and the experimental results is very good, especially for the wavebreaking time and the maximum energy of the hot electrons.
