| 摘 要： | 本文提出一种由线性定常微分方程直接求取差分方程的简便算法,並对该算法给出了数学证明。该算法既适于手算,也适于计算机计算。当由高阶微分分程求取差分方程时,该算法表现了十分明显的优越性。

| Abstract: | This paper Tecommends a new calculation method to directly obtain difference equation by means liner differential equation.
A mathematic identification is made of it. This method is suitable for calculating eot oely by mae but also by cemputcrs. While a difference equatioe is to be ebfaieed from a high-erdered differeetial equation, this method shews advaetagcs obviowsly |
