摘　　要：建立原子在辐射场作用下的模型,用微扰理论方法求解出原子处于两能级的几率.讨论了原子在弱宽带辐射作用下的行为,得到了当v接近vba,且vbat 1时,若Eb>Ea,则原子从辐射场吸收能量,Ea>Eb时,原子发射能量的结论,及较大的跃迁几率所对应的频率在[vba-(1/t)]到[vba+(1/t)]之间的结论.A model is built when atoms in the radioactive field. By means of the perturbation method, the probability is solved for atoms in two energy levels. The action of atoms in the radiation of weak broadband is discussed. When v is close to vbo,and vbot≥1 ,if E 〉 Ea, atoms absorb energy from the radioactive field, if Eo 〉 Eb, atoms transmit energy. And the conclusion is gotten that the corresponding frequency of transition probability is between [vba-（1/t）] and [vba＋（1/t）].
