The creep strain rate sensitivity can be determined from the relationship between the creep hardness and creep strain rate by the definition of "work of indentation".
基于压痕做功概念定义了压痕蠕变硬度和蠕变应变速率，从而给出钎料的蠕变速率敏感指数。
Dualistic regression coefficients of two parameters (steady creep rate and creep damage rate) of the HP-50 reformer tubes are calculated.
计算了HP 5 0转化管稳态蠕变速率参量和蠕变损伤速率参量的二元回归系数。
The creep rate of the slates are also fitted. The results show that the creep rate decreases gradually until it reaches the steady rate.
同时，对板岩蠕变过程中蠕变率的变化情况也进行相关的拟合，显示出板岩蠕变率逐步减小到稳态蠕变的过程，取得较好成果。
