用标准柴油和试验柴油（ 为提高磨料浓度加入直径１５ μｍ 石英２ ｇ／Ｌ） ，分别进行２０ ｈ 的模拟强化试验。对试验结果进行了分析，得出了精密偶件磨损的种类、特征、原因及规律。
Standard diesel and test diesel (20 g of quartz with a diameter of 15 μm added to increase the abrasive concentration) were subjected to a 20-h simulated enhancement test. The test results were analyzed, and the types, characteristics, causes and rules of the wear of precision coupling parts were obtained.
