摘　　要：用发射光谱法研究了Ｎ＋２和Ｎ＋与Ａｒ碰撞产生的激发和电荷转移激发，获取了丰富的光谱信息。计算了各发射光谱线的发射截面，并研究了它们与入射离子能量的依赖关系。同种元素的分子离子和原子离子Ｎ＋２和Ｎ＋与Ａｒ碰撞引起的谱线发射截面的对比中发现了一些有趣的结果。The excitation and charge transfer excitation produced in collisions of N + 2 and N + with Ar have been investigated by use of emission spectroscopy, and an abundance of spectral informations were acquired. The emission cross sections of every spectral line and their variation with energy of projectile are calculated. A comparison of the emission cross sections between N + 2-Ar and N +-Ar collision system has been made, and some interesting results are found.
