摘要: 本文采用两步隐式差分格式研究了自由边界载流等离子体柱的电阻螺旋模不稳定性。发现等离子体温度剖面越宽和越高,m=2的撕裂模的线性稳定就越好。计算结果与实验相符合。

Abstract: In this paper we employ a two-step implicit difference scheme to study numerically ths resistive helical instability of current-carrying plasma column with free boundary. It is found that the wider and higher of the plasma temperature profile, the better linear stabilization of the tearing mode m=2 will be, The results agree with experimental one.
