本文用ＤＳＣ方法研究了抗氧剂对新型冷冻机油热氧化稳定性的影响。实验发现防老剂Ａ和酚噻嗪能很好地提高新型冷冻机油的热氧化稳定性，并且抗氧剂的浓度对冷冻机油的热氧化稳定性有较大的影响
In this paper, the DSC method was used to study the effect of antioxidants on the thermal oxidation stability of a novel refrigerator. It was found that antioxidant A and phenothiazine can improve the thermal oxidation stability of the novel refrigerating machine oil, and the concentration of the antioxidant has a greater influence on the thermal oxidative stability of the refrigerating machine oil
