摘　　要：结合海森堡方程,利用不变本征算符法,给出了存在坐标耦合和动量耦合的双原子分子的能级间隔信息.计算结果与求解薛定谔方程得到的结果一致,且推导过程简洁易懂,该方法能够培养和提升学生运用量子力学解决复杂物理问题的能力.The energy-level gaps for coordinate coupled and momentum coupled two atoms molecule are presented by using invariant eigen-operator method within Heisenberg equation.The results obtained by this bandy method are in good agreement with the date calculated by Schrdinger equation.This method could train and improve the ability of students in solving complicated physics problems with quantum mechanics.
