利用动力学变分理论，得到了氘-氚托卡马克等离子体中由聚变产生的α粒子驱动的自举电流的一般解析表达式。采用了一种自伴随形式的线性化库仑散射算子，它同时包含了能量和俯仰角碰撞。该公式用于预测与国际热核实验反应堆概念设计（ITER CDA）参数相似的反应堆条件下α驱动的自引导电流[ITER文献系列，第18号（国际原子能机构，维也纳，1991年）]。结果与使用另一种技术获得的结果非常一致[Hsu et al., Phys.]。[j].生物工程学报，2009,27(2)。
A general analytic expression for bootstrap current driven by fusion‐born alpha particles is obtained in a deutrium–tritium tokamak plasma using a kinetic variational theory. A self‐adjoint form of linearized Coulomb scattering operator has been used, which includes both energy and pitch angle collisions. The formula is applied to predict alpha‐driven bootstrap current in a reactor condition similar to that of the International Thermonuclear Experimental Reactor Conceptual Design (ITER CDA) parameters [ITER Documentation Series, Number 18 (International Atomic Energy Agency, Vienna, 1991)]. The result agrees well with results obtained using another technique [Hsu et al., Phys. Fluids B 4, 4023 (1992)].
