用聚丙烯酰胺和黄原胶溶液对毛细管中的滑移现象进行了实验分析。这些聚合物溶液在流动中呈现具有不同构象的大分子。研究了聚合物溶液的分子构象对滑移速度的影响。当黄原胶溶液的离子强度增加时，以及当毛细管的材料改变时，观察到滑移速度的相当大的变化。在黄原胶溶液中测得的幅度比在聚丙烯酰胺溶液中观察到的幅度大得多。
The slip phenomenon through capillaries has been analyzed experimentally using solutions of polyacrylamide and xanthan gum. These polymeric solutions present macromolecules with different conformations in flow. Attention was given to the influence of molecular conformation of those polymeric solutions upon the slip velocity. Considerable variations on the slip velocity were observed when the ionic strength of the xanthan solution was increased and also when the material of the capillaries was changed. Measured magnitudes were much larger in the xanthan solutions than those observed in the polyacrylamide solution.
