中文摘要：

从分子设计的观点出发,合成了1种新型的含氮杂环硼酸酯添加剂.采用四球摩擦磨损试验机评价了其在液体石蜡中的摩擦学性能,并采用扫描电子显微镜观察分析钢球磨斑的表面形貌.结果表明：在液体石蜡中加入含氮杂环硼酸酯添加剂后,承载能力有较大提高,磨斑直径明显减少.

英文摘要：

From the point view of molecular design, a kind of nitrogen - containing heterocyclic borates as lubricant additive is synthesized. The tribological properties of nitrogen - containing heterocyclic borate as additive in liquid paraffin are investigated on a four - ball tester. The morphologies of the worn scars are observed by means of scanning electron microscopy. The results show that the load - earrying capacity and the antiwear performance of the liquid paraffin with the additive added are improved, and wear scar diameter is decreased in comparison with the base oil.
