摘　　要：利用抛物线坐标系的定义以及平面上的抛物线方程和抛物线参数方程,对有限长抛物线电流通过磁矢势的计算、磁矢势的旋度计算,来得出该有限长抛物线电流在对称轴上的磁感应强度的理论值,再运用软件MATLAB画出该对称轴上不同位置磁场的具体值的变化图像来直观认识,从而全面了解有限长抛物线电流在对称轴上的磁场分布特点.Using parabolic coordinate system and the definition of the plane parabolic equation and parabolic equation parameters,the finite length parabolic current through the calculation of the magnetic vector potential and magnetic vector potential of curl,to derive the finite length parabolic current in the magnetic induction intensity on the axis of symmetry of the theoretical value,and using the software MATLAB to draw different location of the specific value of the magnetic field on the axis of symmetry change images to intuitive understanding,so as to get a comprehensive understanding of finite length parabolic current in the magnetic field distribution on the axis of symmetry.
