物体表面越粗糙不平，它的分子就越容易更多地与接触表面的分子相粘合，因此就会产生更大的摩擦力。
The more rough and jagged something is, the more easily more of its molecules will come into contact with molecules on the surface it touches, and thus the greater force of friction they will exert.
摩擦力之所以产生，是因为两个表面上的分子彼此粘合，当表面试图移走并打破这种粘合时加以抵抗。
Friction arises because the molecules on both surfaces bond with each other, and resist when the surfaces try to move away and break the bonds.
研制出由多组份粘合剂、混杂纤维及特殊填料制成的无石棉高摩擦系数合成闸片。
There were developed asbestos free high friction coefficient composition brake pads made of poly compound adhesive agent, hybrid fiber and special fillings.
