例句
-
1·The mechanism of the racemization was discussed.同时也论述了氨基酸消旋的反应机理。
-
2·Racemization is found with optically active substrates.发现旋光基质有外消旋作用。
-
3·Racemization is found with optically active substrate substrates.发现旋光基质有外消旋作用。

-
5·Dynamic resolution technology combines the resolution with racemization in situ.动态拆分技术是将拆分反应与现场消旋化反应相结合的技术。
-
6·Until his group's new report, scientists hadn't compared racemization and C-14 analyses on the same teeth, Buchholz says.截至他的研究小组出台新报告之前，科学家们未曾对比过同一颗牙齿的外消旋化以及碳14分析结果，布赫兹说道。
-
7·The dependence of chain scission and racemization on temperature results from molecular motion, "cage effect" and steric hindrance during recombination.分子量降低和消旋作用对温度的依赖性，是由于分子运动和笼罩效应以及重合的空间位阻效应所致。
-
8·The rate constant of racemization of L-Pro increased with decreasing acidity of the carboxylic acid. However, the racemization of L-His was most rapid in acetic acid.消旋速率因羧酸溶剂的不同而异：L-组氨酸在乙酸溶剂中消旋最快，而L-脯氨酸在正丁酸溶剂中最快。
-
9·By the way, if you're curious about why racemization is so much less accurate a clock than C-14 for dating a tooth's age, part of the explanation has to do with temperature.顺便说一下，如果你好奇为什么在判断牙齿年龄方面、外消旋化会比碳14定义的时钟精度差之甚多，那么部分原因与温度相关。
-
10·However, when the researchers applied both techniques to teeth, they realized that the racemization offered an additional useful detail, a good gauge of an individual's age at death.然而，当研究人员将两项技术一并运用于牙齿上，他们意识到外消旋化提供了一个额外的有用细节，能成为个体死亡年龄的良好衡量标准。
