The crystal structures of them show the photochromism is due to the photoisomerization only from enol form to keto form. According to the results of structure analyses, the intermolecular proton transfer mechanism is proposed for photochromism. We also observed their acidichromism in solution.

采用单晶XRD法得到了这五种化合物的结构，根据结构解析，推测四种光致变色化合物的变色机理可能是分子间质子转移，即吡唑啉酮由烯醇式结构变为酮式结构。

Somebody end the entire series, which should be level nine, that will be 100 percent in the target language.

所以当学完整个系列，也就是第九级，那就会百分之百的变为目标语言了。

And, controversially, some utopian fringe assembles see like this work as the entranceway to a future wITe love is guaranteed since it will be provided chemically, or even genetically engineered from conception.

有争议的是，一部份理想化且处于前沿领域的团体视该项任务为通向未来的一道大门。那时感情将不会有任何风险，因该源于那个概念的化学或基因工程便估计将其变为现实。

Aberrant DNA methylation patterns go beyond the fields of epigenesis. Its mainly about a reaction of cytosine transformation into S-methylcytosine mediated by methyltransferases.

DNA甲基化是表遗传学上研究最深入的一种机制，是由甲基转移酶介导，将胞嘧啶变为S—甲基胞嘧啶的一种反应。

Both upper bound formula and lower bound formula of the global truncation error of Euler method have been derived theoretically.After making certain approximat e processing,the derived upper formula changes into current upper bound formula.

从理论上推导出了欧拉方法的整体截断误差的上限公式和下限公式，作一定的近似后，得到的整体截断误差上限公式就变为现用的整体截断误差上限公式。

Any of the three sisters Stheno, Euryale, and the mortal Medusa who had snakes for hair and eyes that if looked into turned the beholder into stone .

戈耳贡：斯塞诺、尤里安勒和人形的可怕的梅杜萨三姐妹中的任何一个，梅杜萨以毒蛇为头发，看到她眼睛的人都会变为石头

And I will make all my mountains a way, and my paths shall be exalted.

我要使我的一切山岭变为大路，并把我的街道修高。

This has been a transition, in essence, from old-fashioned pig pens to vast excremental hells, unprecedented in nature, containing tens, even hundreds of thousands of animals with weakened immune systems, suffocating in heat and manure, while exchanging pathogens at blinding velocity with their fellow inmates and pathetic progenies.

这在本质上就是从老式猪圈变为巨大粪便地狱，其特点前所未有。这种转变使得数万乃至数以十万计的动物免疫系统受到削弱，高温和粪便令动物窒息，而病原体对动物同伴和可怜的后代的传播速度则令人吃惊。

This puts forward many kinds of requests for teacher. Requesting the teacher to not only change the idea, but also change the role, from the executer of curriculum implementation into the constructor and developer of curriculum. So the teacher participating curriculum development is a very important aspect .

要求教师不仅要转变观念，而且要转变角色，由原来课程实施中的执行者变为课程的建设者和开发者，其中教师参与课程发展就是其中的一个重要方面。

Do you know, i need you to come back
