基于多组态Dirac-Fock方法，利用Flexible Atomic Code软件计算了NII离子的能级、跃迁几率、碰撞截面和碰撞激发速率系数等原子参数.用碰撞辐射模型计算了谱线强度比I_（567.96）nm/I_（500.52）nm。得到了6个闪电等离子体通道的温度，与多谱线法得到的温度一致。
The atomic parameters of the NII ion, including the energy levels, transition probabilities, collision sections, and collision excitation rate coefficients, have been calculated based on the multi-configuration Dirac-Fock method by implementing Flexible Atomic Code. The ratios of line intensity, I567.96nm/I500.52nm , have been calculated by using the collisional-radiative model. The temperatures of six lightning plasma channels were then obtained, and they are consistent with temperatures obtained by using the multi-spectral lines method.
