While polymer solution flows through the capillary of Ubbelohde viscometer,the adsorption of polymer molecules on the surface,sometimes,seriously changes the physical and chemical properties of the surface,especially when electrolyte is added into the solution.
当聚合物溶液流过乌氏黏度计的毛细管时,由于聚合物分子在毛细管表面吸附,该表面的物理和化学性质将发生很大的改变,尤其是当溶液中含有大量的电解质时这种情况更为突出。
