对映现象

The appearance of-enantiomer after incubation with single-enantiomer revealed the enantiomeric inversion of-isomer to its antipode. While no obvious stereoselective degradation or enantiomeric inversion were observed in other test soils.

左右旋对映体在3~#土壤中的降解速率有明显差异，二者半衰期相差0.95周；添加外消旋体培养6周后ER值达到1.65，表明左旋体被优先降解；同时在该土壤中存在左旋体向右旋体的转化现象；在其他几个土壤中均未有明显的选择性降解或对映体转化现象。

President Lin Chun-shin pointed out that the health concept described in The Yellow Emperor's Canon of Internal Medicine was a set of rules derived from everyday experience of living in ancient China.

林俊兴董事长认为，《黄帝内经》所讲述的养生概念，反映的是古代中国从生活经验中归纳出的法则，当中的阴阳五行学说亦是当时中国人对宇宙运行的现象解释，读者必须先对这些古中国的思想体系要有基础的认知，才能理解其中的指涉，再辅以西方解析科学的观点交互映证，撷取东、西文化之长，是未来新文明的趋势。

In order to survey the numerical diffusion induced by mesh rezoning and variables remap in ALE method,some calculations had been done,and comparisons show that the smoothing does exist,but the numerical dissipation is not serious,it do no harm to physical picture.

为考察ALE方法网格重分、物理量重映导致的数值扩散对计算精度的影响，进行了一些计算比较，结果显示，虽然存在一定程度的抹平现象，但是网格重分带来的数值耗散并不大，对物理图象并没有显著的影响。

Some compounds possessing chiral center themselves may be racemates and appear racemic phenomenon in the extraction and separation from medicine herbs, structure modification and chemical synthesis.

但是，由于含有手性中心的中药有效成分本身可能是消旋体、或者在分离提取、结构改造及化学合成时会出现外消旋化现象，使新药研制与开发中面临对映体成分的分离制备、体内手性药物分析及对映体特异性药代动力学研究等重大难题。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
