摘　　要：针对授课过程中学生对中断优先权以及中断屏蔽等概念不理解的情况设计了一款简单实用的由8031组成的中断实验系统.通过该实验,可以直观地看到中断、中断优先权、中断屏蔽、外中断源扩展的过程,使学生较容易地理解掌握单片机控制系统中中断的处理方法,提高了实验效果.A simple and practical interruption system is designed composed of Intel8031,as the students can not master interruption priorit y and interruption shield clearly du ring the lessons.Interruption,int errup-tion priority and interruption shie ld can be demonstrated,and the expan ding course of ex-interruption sour ce can be seen by this experiment.Thus t he students can master the interrupt ion disposing means of controlling system of single-chip computer and t he experimental effect is improved.
