摘　　要：应用中断控制技术测量不同频率方波信号的脉冲宽度。实验结果表明:脉冲宽度中断控制的可靠性与准确性完全取决于合理安排外部中断请求的开放时机,与外部中断请求的有效触发状态无关。本实验为实际应用MCS-51系统的外部中断控制技术提供一个范例。The pulse width measuring of the different frequency square wave signals was done by using interrupt control technology. The measure results show that the reliability and accuracy of interrupt control depend on absolutely the external interrupt request open occasion, have nothing to do with the touching state. The experiment provides an example for using the external interrupt control technology of MCS51 system.
