Objective: The purpose of this study was to evaluate the outcome of the part corneal scar resection via minimal invasive surgery and to determine the feasibility of the application of the keratocytes cultured in vitro to repaire the tissue defection.

Objective To explore the relationship and regularity between traumatic corneal scars and astimagtism,and lists its simple equation of linear regression.

The adhesion property of Au/NiCr/Ta multi-layered metallic films was investigated by the indentation method,rolling contact fatigue method and scratch method with both friction and acoustic emission modes.

Au/NiCr/Ta and Au/NiCr metallic multilayers were deposited on A1203 substrate by magnetron sputtering and their critical load (La) was studied by scratch method with friction and acoustic emission mode, moreover, the scratch curve and morphology of metallic films were compared with TiN film.

The adhesive power between silicon film and glass substrate is measured by scratch test .

Factors of effects on TiN coating adhesion strength dctermined by scratch test have been investigated.

The critical load (Lc) was measured by scratch test with acoustic emission sensor.

In order to extend its application scopes,this paper introduces the principle of single-pass pendulum scratching test and its applications to test wear resistance of conventional metallis materials,ductile-brittle transition of quasi-brittle materials,wear resistan.
