摘　　要：材料力学性能的时间相关特性对结构设计非常重要,尤其是长期力学性能的准确信息是结构强度和寿命分析的基础。结合近期研究进展,对影响高聚物时间相关力学性能和长期力学加速表征的主要因素进行了分析,对高聚物等流变材料长期力学性能的加速表征方法和技术以及涉及的基础问题进行了简要评述。The time-dependent characteristics of materials are very important for structural design. The accurate information of their long-term mechanical properties is crucial for structural strength analysis and lifetime prediction. Some key factors to the time-dependent mechanical properties of polymeric materials are introduced, and the recent advances and some basic problems in the studies on accelerated characterization method of long-term mechanical properties,especially the creep behavior,are reviewed briefly in this paper.
