So we understand to once and actually usually take place of the bad factory house adds plant egg white(soybean egg white etc. corn egg white) in the origin should be the milk powder of animality egg white, this is already the first floor to cheat and commit crime, dishonest at least, but the widespread phenomenon in the in view of the fact industry, and have no obvious side effect to the human body, therefore is connive;But the protein content in the original inferior product very low, unexpectedly meet more unscrupulous plant egg white raw material to provide a company, add three gather cyanotype An, result in as a result currently result;Here our for the time being imagining is the beperhaps havior of the supplier, perhaps is three deer companies have intention to add, the basic reason for add lies in a current Kai surname settle nitrogen protein measurement method can test an always organic nitrogen content, rather than the nitrogen content in the particular protein, therefore, the method blemish was fume by the cupidity the exploitation that the milk powder manufactories of heart speculate, make the false and inferior product deceive to reach to mark, because they know three chlorine cyanotype An toxicities are again very small, disguise a protein content to reach a mark in the examination, but they didn't thought of that the toxicity is pimping three chlorine cyanotype An exactly will bring serious Bi to baby kid to wet system stone calculus, we even can guess, other adults of three deers use a milk powder in must also imply in great quantities similar chemistry product, just the adult will not get instant results of is endanger by body.

那么我们了解一下，实际上经常发生的不良厂家在本应该是动物性蛋白的奶粉里添加植物蛋白，这已经是第一层欺骗和犯罪，至少是不诚实了，但由于是业内的普遍现象，且对人体无明显副作用，因此被默许；而本来劣质产品中蛋白质含量就很低，没想到遇到更缺德的植物蛋白原料提供商，添加三聚氰胺，结果造成目前后果；这里我们姑且想象也许是供应商的行为，也许是三鹿公司有意添加，添加的根本原因在于现行的凯氏定氮蛋白质测定方法只能测试总有机氮含量，而非特定的蛋白质中氮含量，因此，方法缺陷被利欲熏心的奶粉制造商们所投机利用，使伪劣产品蒙混达标，因为他们知道三氯氰胺毒性很小，又能在检测中伪装蛋白质含量达标，但他们就没有想到毒性很小的三氯氰胺却恰恰会对婴幼儿造成严重的泌尿系统结石，我们甚至可以猜测，其它三鹿的成人用奶粉中一定也含有大量类似化学制剂，只是成人不会立竿见影的受到身体危害。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
