托卡马克中粒子输运临界模型的研究

Researched of the Critical Model of Particle Transport in Tokamak

应用粒子输运模型来研究粒子在离轴加热时粒子分布关系,得到了粒子输运的密度分布函数与中心位置以及传输参数的情况,计算表明,在临界状态时,其粒子密度的剖面分布远离单一粒子分布状态的中心位置,剖面峰值相应地在减小,当传输参数增大时,中心粒子密度分布剖面在相应地增大。

A distribution function of the particle was researched under off-axis heating in the transport models, the distribution of the particle, the transport parameter and the center position were found. It is shown that the particle distribution will be aparted from the center position of the single distributions on particle when the distributions is critical state, the center density profile is enlarged with the transport parameter is enlarged.
