现代信息技术已经成为我们生活和工作中不可或缺的重要部分。现代信息技术把我们带进了“数字时代”。人们把一条条信息转换成一串串由“0”和“1”组成的二进制数据,通过电路的“断”、“通”来传递信息和储存信息。完成这种功能的电路就是数字电路。数字电路又称逻辑电路。上海物理教材将“逻辑电路”这一具有时代气息的内容单独列出,突现其重要地位。上海“二期课改”启动时,负责课改的徐淀芳主任提出:“按照课改要求编写教材设计新实验,按照新实验要求研发新
Modern information technology has become an integral part of our lives and our work. Modern information technology brought us into the ”digital age.“ People convert a piece of information into a string of binary data consisting of ”0 “ and ”1 “, passing information and storing information through the circuit’s ”break“, ”pass“. The circuit that accomplishes this is the digital circuit. Digital circuit, also known as logic circuit. Shanghai physics teaching materials will be ”logic circuit “ the contents of this era with a separate list, highlighting its important position. At the start of Shanghai ”Phase Two Curriculum Reform“, Director Xu Dianfang, who was responsible for the curriculum reform, proposed: ”According to the requirements of curriculum reform, we should write a new experiment of teaching material design and develop a new experiment according to the new experimental requirements
