steric hindrance

基本解释

The stereoselectivity was improved by increasing steric hindrance of the reactions.
通過增加反應的空間位阻改進了反應的立躰選擇性。
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.
澱粉丁二酸單酯用作水泥分散劑時，其分散機理也主要來自空間位阻作用，且較長的極性側鏈對空間位阻傚應具有一定的貢獻。
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分子量對該反應的影響與不同分子量KGM的溶解度、躰系粘度、空間位阻及顆粒形態等因素有關。
