Because of the low bootstrapcurrent in central area of plasma, the non-induced current driving is necessary for the request of plasma balance.
由于等离子体中心区域自举电流比较小，为了满足等离子体平衡要求，非感应电流驱动是必不可少的。

After the induced current damp out, the neoclassical bootstrapcurrent is the best method to maintain the needed stable current in a steady-state tokamak reactor.
The ratio of the bootstrapcurrent to the total plasma current is analyzed before and after wall conditionings of the ohmically heated discharges in the HT-7 tokamak.
