给出了自举电流的简单物理图，并简要讨论了自举电流的经典和非经典理论。本文回顾了该电流在多极体、仿星器和托卡马克中存在的实验证据，重点讨论了它在托卡马克中的存在。本文介绍了JET的最新数据，表明在h模式等离子体中存在大的自举电流（约1 MA）。最后讨论了该电流的存在对未来高温托卡马克实验的影响，特别强调了它在扩大电流剖面和稳定锯齿中的作用。
A simple physical picture of the bootstrap current is presented and the classical and nonclassical theory of it is briefly discussed. The experimental evidence for the existence of this current in multipoles, stellarators and tokamaks is reviewed with the main emphasis being on its existence in tokamaks. Recent data from JET indicating the presence of large bootstrap currents ( approximately 1 MA) in H-mode plasma is presented. Finally the implications of the existence of this current in future high temperature tokamak experiments is discussed, with particular emphasis on its role in broadening the current profile and the stabilisation of sawteeth.
