Based on the fatigue cumulative damage models, a damage evolutionequation for flexural fatigue of SFRPC slabs is set up.
结合原有的混凝土疲劳损伤模型，建立了预应力钢纤维混凝土板的疲劳损伤演变方程。

The local equilibrium distribution function of lattice model evolutionequation is constructed by use of multi scale analysis.
它是运用多尺度分析方法，构造出格点模型的演化方程的局部平衡分布函数。
