介绍了在已知环形轴对称等离子体平衡位形的条件下,建立磁力线为直线的坐标系的方法。该坐标系被广泛应用于托卡马克等离子体的磁流体稳定性和动理论物理问题的理论分析,但文献中对坐标系建立方法却很少有介绍。结合几类托卡马克位形和球形环位形,对该类坐标系的特征进行了分析。
介紹瞭在已知環形軸對稱等離子體平衡位形的條件下,建立磁力線為直線的坐標繫的方法。該坐標繫被廣汎應用于託卡馬剋等離子體的磁流體穩定性和動理論物理問題的理論分析,但文獻中對坐標繫建立方法卻很少有介紹。結閤幾類託卡馬剋位形和毬形環位形,對該類坐標繫的特徵進行瞭分析。

A method for constructing the magnetic coordinates in which the magnetic field lines are straight is described. This coordinate system is widely used in the magnetohydrodynamic stability and kinetic physics analysis and calculations for tokamak plasmas, however, there is less detailed description about its construction in literatures. Here we describe the basic features of this coordinates for several kinds of tokamak and spherical torus configurations.
