steric hindrance 中文意思是什麼
steric hindrance
解釋
【化學】位阻現象。-
Macromolecules cannot approach the ligand owing to steric hindrance of the matrix.
由於載體的立體位阻的關系，大分子化合物不能接觸到配基。 -
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
綜上所述，本文用兩種不同方法制備了不同聚合漆酚納米無機物雜化材料，研究了合成方法，結構特徵及性能等。 -
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對顆粒分散的影響主要體現在對顆粒間雙電層靜電排斥力的改變；添加合適分散劑可以改變顆粒在水中的分散性；無機電解質的分散機制主要是增加顆粒表面的雙電層靜電排斥作用能，而高分子分散劑的分散機制主要是增加顆粒的水化膜排斥能和位阻排斥能；復合分散劑的分散效果要優于單一分散劑；提出了用經時損失性來評價分散穩定性。
