steric hindrance

基本解释

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。
The dispersing ability of SSHE as cement dispersant also came from steric hindrance effect and long side chain contributed to steric hindrance in a certain degree.
淀粉丁二酸单酯用作水泥分散剂时，其分散机理也主要来自空间位阻作用，且较长的极性侧链对空间位阻效应具有一定的贡献。
These could be related to the difference in solubility of KGM, viscosity of the reaction system, steric hindrance, and granule structure of KGM with different Mw values.
KGM分子量对该反应的影响与不同分子量KGM的溶解度、体系粘度、空间位阻及颗粒形态等因素有关。
