The result shows that ponceau 4R has four obvious fluorescence spectral peaks respectively located at 420,530,635 and 687 nm,each of these fluorescence spectral peaks has different best induced light,and the corresponding fluorescence spectra were listed.

文章分别从理论与实验上对220-400 nm不同激发波长下胭脂红标准溶液的荧光光谱进行了分析，结果表明，胭脂红可以产生较强的荧光，分别在420，530，635，687 nm波长处产生了4个荧光峰，各荧光峰的最佳激发波长也不尽相同，文章给出了相应的荧光光谱图。

Entitled to do the process, it can not clear the subject pooled together on the computer experiments.
