例句

• The results indicate that the larger steric hindrance in the amino alcohol unit of Schiff base ligands leads to higher enantioselectivity.

  结果表明，氨基醇部分的结构空间位阻越大，产物亚砜的对映选择性越高；

• The stereoselectivity was improved by increasing steric hindrance of the reactions.

  通过增加反应的空间位阻改进了反应的立体选择性。

• Thus, we concluded that the steric hindrance of C-terminus might play an important role in opioid receptor affinity.

  因此我们推测C-末端空间位阻的大小对于阿片受体的活性可能起着很重要的作用。

• Macromolecules cannot approach the ligand owing to steric hindrance of the matrix .

  由于载体的立体位阻的关系，大分子化合物不能接触到配基。

• In the forth chapter, we solved the problem of steric hindrance in the third chapter.

  本文第四章解决了第三章中位阻太大，不能形成三桥联分子的问题。

• Because of the steric hindrance, the isopropylated 2-MN can gain higher 2, 6-selectivity than the methylated one.

  而异丙基取代的2-甲基萘由于异丙基基团的空间位阻效应，可以获得较高的选择性。
