本文通过考察三种具有不同π电子数的有机共轭分子在不同溶液中的光谱特性，观察其激发光谱和发射光谱的变化情况，比较同一分子在不同溶液中的荧光量子产率，并通过对各类有机共轭分子溶液的光谱分析比较，以获得有机共轭分子的发光受溶剂影响以及同一溶液中不同有机共轭分子间发生非辐射共振能量转移的信息。

One cause is that little information of solid spectrum is available from experimental data, because the solid always appears ruleless broadband absorption and emission spectrum.

另外，目前处理固体光谱广泛使用的理论是晶体场理论，而晶体场理论只能对固体光谱给出定性的分析，而不能给出定量的解释。

We show that the atomic c.m motion dont affect the atomic spectrum phase sensitivity when there is no correlation between atomic cm. motion and the field. With the increase of the average energy for atomic cm. motion, the peaks of the emission spectrum move towards each other, their heights change according to the state of the field and atomic motion. While there is correlation between atomic c.m.

当原子质心运动与光场无关联时，原子质心运动不影响原子发射谱对原子偶极矩和光场相对相位的敏感性，随着原子质心运动平均能量的增加，原子发射谱峰间的相对距离变小，峰高的变化与原子质心运动和光场所处的状态有关。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it.
