%X 采用差示扫描量热（DSC）和动态力学分析等方法研究物理老化对氟橡胶F<sub>2314</sub>性能的影响。结果表明：在45 ℃下进行物理老化，随着物理老化时间的延长，氟橡胶F<sub>2314</sub>的储能模量增大，损耗因子减小；DSC吸收峰的热焓没有明显变化，但峰位向高温方向移动；松弛模量增大，且增幅逐渐增大。;The physical aging of fluoropolymer F<sub>2314</sub> was studied by differential scanning calorimetry （DSC） and dynamic mechanical analysis.The results showed that，as the time of physical aging at 45 ℃ prolonged，the storage modulus of F<sub>2314</sub> increased，the loss factor was decreased；the enthalpy of DSC absorption peak had no significant change，but the peak position moved towards higher temperature zone；the relaxation modulus increased and the amplitude increased gradually
