利用自洽平衡，研究了任意长宽比托卡马克中的自举电流。推导出了自举电流作为压力、温度、总电流分布以及器件极向β和纵横比的函数的经验公式。将该经验公式与ITER小组得到的公式进行了比较，并与分析结果(适用于大长宽比)进行了比较。结果表明，实验结果与大长宽比实验结果吻合较好，但与ITER小组的经验公式不太相符
Using a self-consistent equilibrium, the bootstrap current in a tokamak of arbitrary aspect ratio is studied. An empirical formula is deduced which determines the bootstrap current as a function of the pressure, temperature and total current profiles as well as the poloidal beta and aspect ratio of the device. This empirical formula is compared with an expression obtained by the ITER group; also a comparison with an analytical result (valid at large aspect ratio) is made. It is found that the empirical result determined here agrees well with the large aspect ratio result, but not so well with the empirical formula of the ITER group
