摘要
文中综述了近三十年关于橡胶在热氧老化下物理机械性能变质规律的认识和掌握,包括性能变化与时间关系,性能变化与温度关系及它同时与时间和温度关系的研究,以及表示这些关系的各种数学模型。并涉及了表征老化的一些重要参数例如活化能、老化温度系数测定的一些基本情况。
\ The paper summarizes the degradation rule of physical mechanical property of vulcanizate during the period of heat ageing, which involves the relationship between the property, variakble tempreture and time. The every math modal of all relations, some important parameters and the measurement of age tempreture coefficient are also related in it.
