摘　　要：首先介绍了555时基电路的结构与工作原理,重点讨论了555时基电路的四种基本工作模式,即单稳态、双稳态、无稳态和定时工作模式,最后列举了555时基电路在电子、电器等领域中的应用实例。实例电路结构合理,设计新颖,针对性和实用性强,具有普遍性、示范性和经典性。The structure and principle of the 555 time base circuit are introduced firstly. The emphases of disscust,ion is focus on four kinks of basic work mode, namely, monostabillity work mode, twin-steady work mode, multivibrator and timing work mode. The application instances of the 555 time base circuit in the electron and electrical equipment field are specialized. The structure of the circuit is in reason, and the design is novel, the pertinence and practicability is better. The circuit have universality, demonstration and classic.
