rubbing friction的例句大全

The smallest friction coefficient of the graphite at 400 ℃ in air was attributed to the thermal chemical reaction among the carbon atoms of high activity and the atmospheric oxygen, which led to the formation of a reaction film with good lubricity on the rubbing surface.

其原因在于，石墨在较高温度下同空气发生氧化反应，在摩擦表面形成具有减摩作用的反应膜，从而使摩擦系数减小。
