steric hindrance meaning in English
【化学】位阻现象。
Examples
- 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 another way , they prevented ion exchange process in some degree because of space steric hindrance . in short , this paper will make a good foundation for further application research about urushiol hybrid material and electropolymerization in future
综上所述，本文用两种不同方法制备了不同聚合漆酚纳米无机物杂化材料，研究了合成方法，结构特征及性能等。 - The interactions between particles were discussed based on dlvo and edlvo theories . experiment results show the effect of the ph on the dispersion is due to the repulsion interactions of electrical double layer ; and addition suitable inorganic dispersant or organic macromolecule dispersant results in improvement the stabilization of the dispersion . the main action of the inorganic dispersants is to increase the repulsion interactions of electrical double layer and the main action of organic macromolecule dispersant is to increase hydration shell and steric hindrance
研究表明： ph对颗粒分散的影响主要体现在对颗粒间双电层静电排斥力的改变；添加合适分散剂可以改变颗粒在水中的分散性；无机电解质的分散机制主要是增加颗粒表面的双电层静电排斥作用能，而高分子分散剂的分散机制主要是增加颗粒的水化膜排斥能和位阻排斥能；复合分散剂的分散效果要优于单一分散剂；提出了用经时损失性来评价分散稳定性。
