| 摘 要： | 讨论了抛物形电导率、线性热势电导率、正态分布电导率以及抛物形透明辐射模型下，轴向磁场中电弧的螺旋不稳定性。将所得结果与均匀电流分布情形作比较，稳定区域变大，与实验结果相符。

| Abstract: | The helical instability of arcs with electrical conductivity of a parabolic current profile, linear heat flux potential, normal distribution and transparent radiation of the parabolic distribution is discussed in an axial magnetic field. Comparing the results with those of uniform current distribution, it is found that the stable area is enlarged. |
