test liner

基本解释

The application of electro-hydraulic proportional control technology in the test of liner friction coefficient and the testing principles of friction coefficient were introduced.
介绍了电液比例控制技术在衬垫摩擦系数中的应用及摩擦系数测定的原理。
The waste paper we want: consists of baled corrugated containers having lines of either test liner, jute or Kraft. Prohibitive materials may not exceed: 1%. Total out throws may not exceed: 5%.
需要废纸：捆包瓦楞箱，牛皮箱板纸、黄麻纸或牛皮纸，禁含材料不能超过1%，总废弃量不能超过5%。
This is the only accurate test because if the liner or lock is engaged you can't tell if the blade pivot is precise.
因为当锁定机构压迫刀体时你无法区别是否刀轴精确性，只有这样才能准确测出晃动量。
