水在表面粗糙度高的陶瓷表面铺展会受到阻碍,如果陶瓷表面较为平滑,水能够顺利的在陶瓷表面的铺展浸入到油污与陶瓷界面之间,使陶瓷表面和油污分离开来。
The water's spread would be counteracted on rough surface. If the surface was slick, water could spread into the interface of oil and ceramics glaze, which separated the oil from ceramics.
为此本文采用富士压力测试纸来监测不同表面粗糙度界面的小型螺钉连接件中界面接触压力的分布情况,为今后的设计提供保障。
Fuji prescale film is used to test the pressure distributing of the parts with different roughness. We have acquired some useful results, which is very helpful for future design.
