adj.有碰撞痕迹的，碰撞引起的

collisional excitation → 碰撞激发
collisional activation → 碰撞激活；碰撞活化
collisional quenching → 碰撞猝灭
collisional de-excitation → 碰撞去激发
collisional broadening → 碰撞展宽；碰撞致宽；碰撞变宽；称为碰撞变宽
collisional heating → 碰撞发热
collisional activation mass spectrometer → 碰撞激活质谱计
collisional absorption → 碰撞吸收；碰撞致窄
collisional transition → 碰撞跃迁
