【Abstract】 In this paper the system of ordinary differential equations with a generaltorm is considered,Sufficient and necessary conditions are given for the cxistence ofgeneralized-function solutions of order m,and useful formulae are proved to determineorder numbers of generalized-function solutions,and,moreover,some interesting-properties on the existence are illustrated with examples.更多还原
