S-1-phenylethanol was obtained in up to 19%ee in toluene at 0℃.(4)A series of C_2-symmetric chiralβ-amino alcoholsⅣ-5were synthesized in several steps from natural amino acid L-proline,and applied in the asymmetric borane reduction of prochiral ketones.

4以天然L-脯氨酸为起始原料，经过几步转化合成了以萘环为母体的C_2-对称的手性β-氨基醇Ⅳ-5，将其应用于硼烷对前手性酮的不对称还原反应中，同样，我们也观测到温度影(来源：Ac1BC论文网www.abclunwen.com)响产物构型的现象。

The shoe boots of this kind of design broke semmetry and balanced modelling principle, do one's best helps the change of type design, with popularity slant head last for shaping a shoe close suitably, with modelling of asymmetry of a kind of reduplicative, make whole shoe money bring out the best in each other.

这种款式的鞋靴打破了对称与均衡的造型原则，力求帮样款式的变化，与流行的偏头鞋楦相配合，以一种重复的不对称造型，使整个鞋款相得益彰。

The sequence analysis results of CO I and 16S rRNA gene showed that the much lower divergent level found among the ingroup samples in this study is more typical of what is seen among populations within species.

为了得到四种分析方法一致的沼虾属系统发育关系，我们构建了这四棵树的50%合一树，结果发现沼虾属可分为第二对步足左右不对称的类群和第二对步足左右对称的类群。

Experiments show that:when the concentration of acetone is decreased from 100% to 20%,the absorbance bands at 3538cm-1 and 3441cm-1 of CH3 is redshifted,the absorbance band at 1713cm-1 and 1647cm-1 of CO is redshifted about 19 cm-1 and 21cm-1 respectively.

发现随着丙酮水溶液浓度的减小，丙酮CH3键的对称(3538cm-1)和不对称伸缩振动(3441cm-1)吸收峰位置波数减小方向迁徙，CO伸缩振动吸收(1713cm-1)向波数减小方向移动，丙酮浓度为20％时，迁徒至1691cm-1，减小了约19cm-1；同时1647cm-1处的吸收则迁徙至1626cm-1。
