当原子或分子不受任何外界干涉释放自身多余的能量时，太阳和灯泡本能的发出的普通光。
Ordinary light, from the Sun or a light bulb, is emitted spontaneously, when atoms or molecules get rid of excess energy by themselves, without any outside intervention.
假定原子或分子发射光能和吸收光只能不是一个连续的过程，而是阶梯式发生的。
It is assumed that the emission and absorption of light energy by an atom or molecule is not a continuous precess but occurs in steps.
它将会被取消当分子和原子强烈的散布事件一些波长的光时候，慧星将他们的光辉归功于共呜散布。
It will be recalled that comets owe their radiance to resonance dispersion when molecules and atoms intensely scatter incident light of some wave-lengths.
在层中，太阳紫外线的光借由分离氧分子进原子之内形成新鲜的空气。
In this layer, the sun's ultraviolet light forms ozone by splitting oxygen molecules into atoms.
用改进的PPP-CI方法计算染料分子的跃迁能和电荷密度，结果表明，茚苯胺染料的光退色速率与染料分子中某些原子上的电荷密度有关，单重态氧可能在光退色过程中起着重要作用。
The transition energies and charge densities of dye molecules are calculated by modify PPP-CI method. The results show that the photofading rates are closely related to the charge densities ons…
