The high plasma current allowed in a RFP is expected to be sufficient to heat the plasma to ignition without the need of auxiliary neutral-beam or radio-frequency heating.

在反场箍缩条件下可允许用强等离子体电流充分加热等离子体到点火温度，而不需要辅助的中性束或射频加热系统。

BACKGROUND: Radio frequency ablation (RFA) has widely utilized in the treatment for tumor with minimally invasion. However, the current RFA has disadvantages of little volume of coagulation.

背景：射频消融作为一种有前途的微创肿瘤治疗方法应用越来越广泛，但是现今的射频消融系统还普遍存在消融范围小的问题。
