给出了高能α粒子的新古典输运系数的解析近似表达式。保留了能量散射效应以及通常的减速和俯仰角散射效应。这些公式对于任意纵横比都有效，并且与之前的结果非常吻合，之前的结果使用特征函数展开技术对系数进行了数值评估。新开发公式在国际热核实验反应堆设计活动（ITER EDA）中的应用[J. C. Wesley 和 ITER 联合中央团队，物理学家。 Plasmas 4, 2642 (1997)] 还给出了等离子体条件。
Analytic approximate expressions of neoclassical transport coefficients for energetic alpha particles are presented. The energy scattering effect, as well as the usual slowing-down and pitch angle scattering effects, is retained. The formulas are valid for arbitrary aspect ratios and agree well with the previous results, which numerically evaluated the coefficients using an eigenfunction expansion technique. Application of the newly developed formulas to the International Thermonuclear Experimental Reactor Design Activity (ITER EDA) [J. C. Wesley and ITER Joint Central Team, Phys. Plasmas 4, 2642 (1997)] plasma condition is also given.
