摘　　要：对555集成电路实验项目进行创新设计,使555集成电路的单稳态过程和多谐振荡过程同时出现,并且经过扩展又能实现施密特触发器的功能。Multisim仿真实验结果表明:三种过程的波形鲜明,实验线路实用性强,声光效果的应用又使实验变得趣味生动。The experimental project of 555 integrated circuit has been so creatively redesigned that the monostable process occurs at the same time with the multi-vibrator process and that the circuit can be expanded to act as a Schmitt trigger.The results of the Multisim shows that the three courses are extremely contrasted in wave shapes and the experiment is practicable in the line set and quite fascinating and vivid with the application of the sound and light.
