It was found that with the increase in the oscillating frequency for a fixed oscillating angle, the film thickness increases, which may contribute to the formation of the oil film; however, the maximum pressure and the pressure scope during an oscillation cycle also increase; which may shorten the fatigue life of the bounding surface in the latter situation.

结果表明：在摆程不变的条件下，膜厚随摆动频率增加而增大，有利于润滑膜的建立，但同时会增加1个周期中的最大压力及压力波动幅度，使工件易于疲劳；对于相同凸度量，在低频摆动工况下边缘效应较高频工况下的严重，因此在低频摆动工况下使用滚子设计时需要增大其凸度量。

It was the interactional result of electronegative double bond and branched chain with positive induction effect and space steri.

研究发现，加入不同的添加剂使润滑脂的油膜强度、锥入度和滴点产生不同的变化，并对其产生的原因作了机理分析，认为是由于极压抗磨添加剂分子中带负电性的双键和带正诱导效应及空间位阻效应的支链共同作用的结果。
