(2)、减法运算 [例 13.1.2] (11001)2 -(110)2 = ? (3)、乘法运算 [例 13.1.3] (1001)2 * (101)2 = ? (4)、除法运算 [例 13.1.4 ] (10111010)2 / (1101)2 = ? 5、二进制 — 十进制的互换规则 (1)、二进制化为十进制 方法:为“乘权相加法” [例13.1.5] 把二进制数 11101 转换为十进 制数。 讲解例题 (2)、十进制化为二进制 方法:为 “除 2 取余倒记法” [例 13.1.6] 把十进制数 37 转换为二进制数。 师:自然界中存在着大 6、关于逻辑电路的几个规定 量相互对立的逻辑状 (1)、逻辑状态表示方法的规定 态，比如电位的高低， 用数字符号 0 和 1 表示相互对立的逻辑状态，脉冲的有无等，这些对 称为逻辑 0 和逻辑 1。 的逻辑状态可用我们熟 常见的对立逻辑状态示例 知的数字符号0和1表 示，但是这里0和1 与看书并完成相关 数学中不同，只是一种知识点 符号称为逻辑0和逻辑 1. 要求学生看书完成知识(2)高、低电平规定 as dispute resolution mechanisms, implement fully the petitioners ' cases "third-party" hearings and supervising system of letters and calls, and to resolve the involved law lawsuit into the orbit of rule of law, vexatious, Twining visit visit, disturbing social order and other malicious extortion, resolutely crack down. Five, improving cadres Vitale, provide strong protection for forest development XI General Secretary stressed that the comprehensive revitalization in Northeast China, needs a high quality, solid style, cadres of the dare to play. Cadre cadres is a pledge, should want to do work and able to do good, enthusiasm is paramount. Treat party cadres, it is necessary to Strict management, and warm care, enable the broad masses of cadres work hard work, this is two parallel principles. In strict accordance with the standards of good cadres selection and appointment, the real officers, dare officers, those who want to play, good as excellent cadres at all levels of leadership in the past. At present, some leading cadres work initiative is not high, beyond political, idle, lazy governance governance, not as, slow, messy and a phenomenon still exist to varying degrees, affected and restricted economic and social development. We must mobilize the enthusiasm of cadres as an urgent task, adhere to combination of incentives and constraints, and adhere to the strict management and warm care, practical solution "for the officers not to" problem, motivate cadres and better lead the masses to an undertaking, the cadres and create the new achievement in a dare to play, good at shows as new.
