It is concluded that active sulfur compounds may improve the oil's EP property but harm inhibition of copper corrosion, antirust property and anti-oxidation stability.
试验表明：活性硫改善了齿轮油的极压性，对抑制铜腐蚀性、防锈性能和抗氧化性能均有不利的影响。

Competitive INHIBITION Competitive inhibitors compete with substrate for an enzyme's active site, lowering the enzyme's likelihood of binding substrate and slowing the observed reaction velocity.
竞争性抑制竞争性抑制剂与底物竞争酶的活性部位，降低酶的约束力基板的可能性，并观察到的反应速度放缓。
