| 摘 要： | 建立了原子在单色辐射作用下的模型，用微扰理论方法求解出原子处于两能级的几率.讨论了原子在单色辐射作用下长时间内的行为，得到了原子因辐射场的影响而变化的速率比能级的衰减速率大的情况下，原子在两能级间振荡，原子和辐射场相互作用越强，辐射场能够与原子发生作用的频率区间越宽,而且原子在单色光长时间辐射作用下高、低能级跃迁的速率不随时间而改变的结论.

| Abstract: | A model is built when atoms in the radiation of monochromatic light.By means of the perturbation method,the probability is obtained for atoms in two energy levels.Long-time action of atoms in the radiation of monochromatic light is discussed.On the condition of the speed of atoms on the influence of radioactive field is more than the decay speed of energy level,atoms oscillate between two energy levels.Atoms and radioactive field interact. Stronger,their frequency district is wider.It is concluded that the transition speed of different energy levels does not change with the time when atoms in the radiation of monochromatic light long time. |
