【摘要】 简述了网络硬件虚拟实验室系统中虚拟元器件与虚拟设备的建模和构建技术。提出模型库需要满足的几个条件 ,在此基础上将面向对象的方法运用到虚拟元器件库和虚拟设备库的建模中 ,根据组成虚拟实验系统的实体对象及其之间的关系来构造仿真模型 ,使模型具有良好的独立性、可扩展性、可维护性和可重用性。用基于 Java语言的 Java Beans组件技术构造具体的虚拟元器件及虚拟设备对象更多还原

【Abstract】 The paper describes the simulation model and the constructional technologies about virtual components and virtual devices in handware virtual laboratory system Based on analysis the requirements of the virtual components library, the object oriented method was applied to the modeling of the virtual components library and virtual device library and the simulation model was constructed by means of the entitative objects composing the system and the relations between them This method can make the simulation model more independent, expansible, maintainable and dupicable Adopition the JavaBeans controller technologies based the language of Java,we design the material objects of virtual components and virtual device更多还原
