Prolonged intake of melamine will damage animal reproduction and urinary systems, bladder/renal stones will further induce bladder cancer.1994 International Programme on Chemical Safety and European Commission coedited International Chemical Safety Manual Vol.3 and International Chemical Safety Cards specify that:: prolonged or repeated intake of melamine might influence kidney and bladder, giving rise to stones. The preliminary investigation of 2007 America pet food contamination incident regards that wheat protein powder doped with ≤6.6%%melamine is the cause of pet food poisoning.

动物长期摄入三聚氰胺会造成生殖、泌尿系统的损害，膀胱、肾部结石，并可进一步诱发膀胱癌。1994年国际化学品安全规划署和欧洲联盟委员会合编的《国际化学品安全手册》第三卷和国际化学品安全卡片说明：长期或反复大量摄入三聚氰胺可能对肾与膀胱产生影响，导致产生结石。2007年美国宠物食品污染事件的初步调查结果认为：掺杂了≤6.6%%三聚氰胺的小麦蛋白粉是宠物食品导致中毒的原因。

We note from the further studies that in the crystals, which sharing the similar crystal structures and coordinational environments, the magnitude of the Stokes shift of the luminescence of the dopant ion is in line with the average covalency of the replaced lattice site. This is because that the nature of Stokes shift is the energy transfer from the luminescent ion to the host lattice. The value of this energy is determined by the frequency of the host lattice in which the frequency is controlled by the chemical bond characters.

更深入的研究发现，在晶体结构和中心离子配位环境非常相似的系列晶体中，掺杂离子发射光的Stokes位移值与其所取代格位的平均共价性成正比的关系，这是由于Stokes位移的本质是发光离子在发光过程中向基质以光波辐射的形式传递能量，这一能量的大小是由基质的振动频率决定的，而基质的化学键性质恰恰决定着基质的振动频率。

Moreover, anything that is the best of its kind, if it be mixed with what is inferior to it, not only takes nothing away from the lesser material, but actually improves it; and therefore if poets, however crude the verses they write, mix the illustrious vernacular with their own crudities, they not only do the right thing but, it seems, are obliged to do so: those of limited ability stand much more in need of help than those with greater skill.

而且，任何出类拔萃的事物，如果与逊色于它的东西相混杂，它不仅不会削弱那低等的东西，反而会提升它；因此如果诗人把高贵的方言掺杂进他们鄙陋的作品中，那么无论他们的诗行如何粗野，他们都是在做正确的事情，而且似乎必须这样做：那些天资有限的人比禀赋卓绝者更需帮助。
