The pressure component inside the boiler, represented by superheater, whose main reason of life loss is long- term creep.

对于以高温过热器为代表的炉内承压部件，其寿命损耗的主要方式主要是长期蠕变。

Because of the randomness of material properties and operation conditions the creep damage of high temperature component is also stochastic.

由于材料性质以及操作条件的随机性，高温构件的蠕变损伤也同样具有随机性。

Through introducing the nonlinear viscoplastic component, this rheological model can describe the transient creep stage, steady-state creep stage and tertiary creep stage.

该流变模型通过引入非线性黏塑性体可以描述岩石流变的减速、等速特别是加速蠕变阶段。
