摘要: 给出了具有抛物形电导率分布的电弧螺旋不稳定性的一个简化线性分析,得到了显式解析解。在外加均匀磁场情况下,理论结果与实验测量符合得很好。同时计算了由自磁场产生的不稳定性增长率,其结果与先前完全的、复杂计算的结果相一致。

Abstract: A simplified linear analysis of the helical instability of arc plasmas is given. Explicit analytic results are obtained. In case of the applied uniform magnetic field, theoretical results are in good agreement with the experimental measurements. At the same time it also calculates the growth rate of the instability generated by the self magnetic field. The results are in agreement with those of complicated calculations once perfectly.
Key words: electrical arc, helical instability, linear analysis
