摘　　要：主要研究了如何使用迭代法求解阶差分方程,利用Java小程序内嵌网页,实现了多种激励下的输出序列(包括零输入响应、零状态响应、全响应)波形的动态绘制。界面交互性强,动态性好,丰富了差分方程的教学,对信号与系统课程的网上教学作了很好的尝试。This article discusses the arithmetical solution of difference equation by using iterative method . By means of setting Java applet in Web page can realize dynamic displaying wave of difference equation stimulated by several inputs, including zero input response, zero_state response and total response. It has an interactive and dynamic interface and so enriches the method of teaching difference equation, it is also a beneficial trail in how to teach signal & system on the Web.
