用Java实现网上结构图实验仿真

基于线性系统仿真的连接矩阵方法，用Java语言开发面向结构图的实验仿真程序，以Applet小应用程序的形式插入网页中运行，实现了信号与系统网上实验教学中的结构图实验仿真。经试用，程序在浏览器中运行正常，可以完成一般线性系统仿真，与以MATLAB，LABView等程序开发的实验仿真程序相比，该程序运行环境简单，几乎所有常用的Web浏览器都支持Java运行，不需另行安装相应组件。对于线性系统结构图，实现了所见即所得的图形化编程环境，具有较好的人机交互性。

Java Program Used in Block Graph Experimental Simulation on Web

In the curriculums of computer and information science,experiments are indispensable.But it is a problem that how to do experiments in long\|distance education on web.A resolution is to substitute virtual experiments for real ones.The applet program which works in web page is written by java language.If the simulation experiments are based on applets,they will never be limited by the simulation enviroment like matlab or labview.To simulate LTI system based on the block graph the junctional matrix method is introduced.Users can operate the graphical interface in the browser by mouses and keyboards,so the WYSWYG graghic programming interfacs to be very friendly to users and runs properly in probation.
