基于非线性波粒相互作用理论，建立了仿星器中二次谐波电子回旋击穿的动力学模型。介绍了一套用电子动量空间离散描述H2电离链的粒子平衡方程，并用数值积分法求解。在不同的预充压力条件和不同的注入功率值下，确定了各物种密度的时间演化规律，并进行了击穿预测。对TJ-II仿星器实验数据的分析与理论结果吻合较好。据作者所知，这是第一次将精确的预测与实验行为直接进行比较。
A kinetic model for second harmonic electron cyclotron breakdown in stellarators, based on the results obtained from non-linear wave-particle interaction theory, is presented. A set of particle balance equations that describes the H2 ionization chain by means of an electron momentum space discretization is introduced and solved by numerical integration. The time evolution of the various species densities is determined and breakdown related predictions are obtained for different prefill pressure conditions and different values of injected power. Analysis of the TJ-II stellarator experimental data shows good agreement with the theoretical results. This is the first time, to the authors' knowledge, that precise predictions are directly compared with experimental behaviour.
