The kinetic curves properties response aging time and temperature were obtained with the coefficient of compression stress relaxation as index of aging property change.
用压缩应力松弛系数作为老化性能变化指标，得出了性能随老化时间和温度变化的动力学曲线。

With calculating property index of compression set and stress relaxation, it obtains a calculation formulation that property changes along with aging time at the special temperature.
This paper discusses theoretical models and numerical experiments of waveform relaxation methods for solving nonlinear differential-algebraic systems of index-3.
