This modification incorporates explicitly the duration of strong earthquake ground motion into the timedependentvariation of the root-mean-square peak amplitude.
这个修正明显地将强震运动的持续时间包含在均方根振幅依赖于时间的变异中。

Stress relaxations are observed at various given temperatures. The variation of stress with time is exponential form and the relaxation time constant is strongly dependent on temperature.
在各种给定温度下，应力随时间均按负指数形式松弛，但应力松弛时间常数强烈地依赖于温度。

The variation of creep at different time is mainly dependent on rate of load and r.
