2 . the creep data were processed and analyzed with mathematical method . based on the experimental results , curve of creep rate versus stress and of creep rate versus temperature were curved 用最小二乘法对蠕变速度与应力及蠕变速度与温度- t的几组蠕变数据进行拟合，得到相应的方程。
4.
It has been discovered that the deformation in the primary creep regime can well described by eqution : - 0 = atm , moreover , the eqution : = a n exp ( - q / rt ) can be used to interpret phenomenally the relationship between the steady - state creep rate and stress , temperature 蠕变的第一阶段也就是减速蠕变阶段的蠕变变形可用? _ 0 = at ~ m来描述。可以唯象地解释稳态蠕变速率和蠕变应力和温度之间的关系。
