摘要
针对具有四个状态系统所建立的模型的修复率μi(x)(i=2,3)用初等阶梯函数进行逼近,给出了系统的半离散化模型,为进一步数值计算打下理论基础.
This paper presents a model of four-state system, We structure an elementary step function to approximate the repair rate μ(x) (i=2,3) in the system, model and presents the semi-discretization model, which provides the theory foundation for the further research of numerical calculation.
