The humidity could change in the room and that could change the friction coefficient.
室内的湿度会随时变化,这对摩擦系数影响很大。
2
The humidity results in low friction coefficient, but the braking presure will decrease the effect.
湿态环境下平均动摩擦系数降低，但随着压力的增大，这种影响减小。
3
The comparison of the results of P01 and P02 showed that P01 had slightly lower coefficient of friction, but its wear was larger, indicating its larger humidity sensitivity.
