中文摘要:
      利用蠕变试验研究了天然橡胶/顺丁橡胶（NR/BR）并用硫化胶在热氧老化过程中的链键断裂和交联特性，并将试验结果与平衡溶胀试验结果进行了比较。实验表明，这是一种切实可行的试验方法，具有设备简单、测试快速而准确的特点。
英文摘要:
      Using the creep test a study was made on the vulcanization characteristics of NR/BR blend vulcanisate and its molecular chain scission and crosslink break during thermal oxidative aging. The test results were compared with those by equilibrium swelling method. Experiments show that such a type of test proves to be practical and feasible，with the features of simple devices and rapid and accurate measurements.
