摘　　要：根据光谱线相对强度和跃迁特性参数值,通过线性拟合一次函数,得到两个拟合参量.借助于这些参量,计算得到特殊激发态或高激发态谱线的跃迁概率.目前在对NⅡ光谱分析的基础上,得到了一条对耦合激发组态谱线的跃迁概率.为求取一些在理论计算中很难处理的特殊组态或高激发态谱线的跃迁概率,提供了一种最新的、简单可行的半经典计算方法.According to the relative intensities of lines and transition parameters, through linear fit of linear function, two fit parameter are obtained. And by adopting these parameters, transition probabilities of spectral lines for special configuration or highly excited states can be calculated. In the present work, on the basis of spectroscopic analysis for N~ spectra, the transition probability whose upper states are pair coupling is obtained. The present work gives a simple and feasible new semi-classical method to calculate transition probabilities, especially for special configurations or highly excited states.
