摘　　要：线性微分方程和方框图是信号与系统中两种重要的系统模型。针对大多数教科书对于由微分方程绘制方框图的讲解不够完善,造成学生难以理解的问题,通过总结和对比已有的方法使学生容易理解和掌握方框图的绘制,从而提高了教学质量并取得了良好的教学效果。Linear differential equation and block diagram are two important system models in the signal and system. However, there are inadequate and imperfect explanations about block diagram drawn with linear differential equations, which makes it difficult for students to understand, This paper summarizes and compares the existing methods which students find easy to understand and grasp the drawing of block diagram so as to increase the teaching quality and achieve the better teaching effect.

关 键 词：方框图 系统模型 线性微分方程
