The compound artificial synovia was prepared according to the table of orthogonal test design, which three factors-Hyaluronic Acid, γ- globulin and Lα-DPPC and five levels were considered.

Supporting the study of artificial articuar cartilage materials, the research and development of an artificial synovial fluid of Hyaluronic acid (HA) was carried out.

A compound artificial synovia was prepared by adding Lα-dipalmitoyl phosphatidylcholine(L α-DPPC) riposomes and γ-globulin to a saline of sodium hyaluronate (HA),by which two kind of tribology slider pairs-PVA-PVA-H/VA-H and PVA-H/316L S.

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 rheological characteristics of an artificial synovia mainly consisting of hyaluronic acid prepared by editors was discussed.

It also has laid a solid foundation for the polytechnic compound talents teaching.

(2)The landslide was a composite landslide including landslide and debris flow and the landslide supplied material for debris flow; if the exterior conditions were more severe (for example.
