【Abstract】 Using J.Mikusinski’s operational calculus,the related formulae,properties and results of differential operators,and the concept and conclusions of series of shifting operators,this paper gives the series solution of more general linear difference-differential equations with constant coefficients when n=3.The result obtained extends the conclusions in[1].更多还原
