steric

Results the particles may have higher electrostatic effect by adjusting the pH value of the medium and have steric hindrance effect by adding the surfactants on the previous condition, which prevent the particles from agglomeration.

结果：调节介质的pH值，使颗粒间处于较高的静电效应，在此条件下加入表面活性剂，使颗粒间又具有空间位阻稳定效应，空间位阻稳定效应可阻止颗粒间的团聚。

Through inorganic coating and organic modification of titanium dioxide respectively, we can improve powder reunion by using organic functional groups steric of titanium dioxide surface. At the same time, the coating of titania with organic functional groups improves the compatibility between the particles and nylon matrix.

通过对钛白粉的无机包覆和有机改性，可利用钛白粉表面较多有机官能团的空间位阻效应改善粉体的团聚情况，同时有机官能团改善了它与锦纶界面的相容性。

There was a research before which found that the osmolyte stabilizing effect have negative correlations with the ratio of polar group surface area of their molecules. However, it failed to consider the molecular volume which could represent the steric exclusion effect, therefore had some deviations.

之前有研究发现渗透剂对蛋白质的稳定能力与它的分子表面的极性基团表面积比例呈反比关系，但忽略了分子体积所代表的空间位阻效应的影响，因此存在一定误差。
