摘要
用原子力显微技术（ＡＦＭ）观测复合人工滑液在材料表面形成的吸附膜的表面形貌图 像，吸附膜上清晰地显示有大量的椭球形分子．该吸附膜的形成可能是复合人工滑液对人工关 节材料润滑性能显著提高的一个重要因素．
In order to find the potential factors resulting in significant improvements in the lubricating be- havior of a compound artificial synovia, which was prepared by ourselves with hyaluronic acid mainly and some proteins and phospholipids, the technology of Atomic Force Microscope (AFM) was used to observe the appearance of adsorbed film on material surface formed by the compound artificial synovia. The results show that adsorbed film exhibits lots of clear elliptical molecules only with the coexistence of y-globulin, Lα -DPPC and Hyaluronic Acid(HA), which means this kind of artificial synovia has a high resistance to shearing action and a significant improvement in boundary lubrication.
