abrasion wear index的用法和样例：
- The relational order of indexes to mileages is acid value, ignition point, viscosity, number of big abrasion particles and severity of wear index.
- Excellent brasion resistance of as cast martensite high Cr iron has been proven under the conditions of low stress and abrasion wear.
- Metal friction and abrasion wear are resulted from mechanics, physical and chemical effect. It is a process in which mechanical,heat,chemical effects synthetically take effect.
- The thesis is about improvement of CBL series oil pump.During the operation of oil pump,the abrasion wear of sealed copper bushing always shortens the pump's life time.
