摘要
利用 J.Mikuinski 的算符演算理论和变数算符概念,给出半直线上二阶变系数线性常微分方程初值问题的连续型差分近似解.
We use the theory of J.Mikusinski's Operational Calculus and the concept of variable number operators,and give the continuous type difference approximation solution of the initial value,question of the second order linear ordi- nary differential equation with variable coefficients which is defined in 0≤t<+∞.
