英语翻译The simple fact shows that the more of the force of friction is got rid of,the farther will the ball travel,and we are led to infer that,if all the impeding forces of gravitation and resistance could be removed,there is no reason why the ball,once in motion,should ever stop. ...
When the load Fn increases, the friction force Ff of the DLC films increases (Fig. 2a). The increase of Ff is because a large Fn can penetrate the particle into the DLC films and thus increase the interfacial adhesion strength. This can be verified by the increase of the number of bonds...
