The thermal oxidization stabilities of high flash point jet fuel at 150-315 °C and 370- 400 °C were examined by JFTOT test. The results show that the thermal oxidization stabilities of jet fuel tested are very good at these two temperature ranges. It is discovered that Cu ion and Fe involve in the thermal oxidization reactions of high flash point jet fuel and that Cu ion catalyzed and participated in oxidation, while Fe ion only acted as a catalyst to promote the oxidation and accelerate the deposition of the unstable compounds in the fuel.

The rolling bearing life of the greases composed of different thickeners and base oils were tested under light load condition.It is found that the maximum life is closely related to the properties of the antioxidant used, which is the main factor influencing the rolling bearing life, and has a linear relationship with amount of antioxidant.With the increase of added antioxidant, the bearing life is prolonged.But if the test temperature increases, due to the increase of the oxidation rate, the increasing trend of the bearing life with antioxidant amount declines.
