摘 要 虽然开放系统是一个流行的名词, 但是对于一般用户, 它却是一个在实际工作中“无法操作”的事物。本文从计算机开放系统的基本特征出发, 通过逻辑推理, 导出描述开放系统的轮廓, 借助于后者使开放系统一词的内涵得到了澄清, 并使它的实现变成了“可操作的”。文中还从IT 实际工作的方便出发, 提出了一个简明的开放系统的工作定义。关键词 开放系统, 轮廓, 可移植性, 可互操作性, 封闭系统, 开放式专有系统-Abstract Although open systems is a popular term, but for the average user, it is a practical work in a "inoperative" things.

The article also from IT to facilitate the practical work, put forward a simple one, the open system of working definition.
