摘　　要：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。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.
