The justification of(13. 2-2)as a representation of spontaneous emission noise is provided by the discussion preceding(13. 1-7) . 根据上面对式（131-7）的讨论，就可以将公式（132-2）看作是自发辐射噪声的表达式。
An atom on an excited upper level can execute a downward transition not just spontaneously but also when photons of the radiation field surrounding the atomic interact with it . 处在较高的激发态上的原子不只可以自发地而且可以在它与原子系统周围辐射场的光子相互作用时发生向下的跃迁。
