　　节 电工和电子技术概述
一、电能的应用及其与生产发展的关系
电工学是研究电能在技术领域中应用的技术基础课程。电能的应用范围是极其广泛的。现代一切新的科学技术的发展无不与电有着密切的关系。
电能的应用，在生产技术上曾引起了划时代的革命。在现代工业、农业及国民经济的其他各个部门中，逐渐以电力作为主要的动力来源。工业上的各种生产机械没备（如机床、起重机、轧钢机、锻压和铸造设备等）都是用电动机来驱动的。机械制造工艺，如电镀、电焊、高频淬火、电炉冶炼金属、电蚀加工、超声波加工、电子束和离子束加工等，都是电能的应用。对生产过程中所涉及到的一些物理量（如长度、速度、压力、温度、水位、流量等），都可用电的方法来测量和进行自动调节，以实现生产过程的自动化。农业上将日益广泛地采用电力排灌设备、粮食和饲料的电力加工装置等。电也是现代物质、文化生活中所不可缺少的，如电灯、电话、电影、电视、无线电广播及X射线透视等都是电能的应用。
随着生产和科学技术发展的需要，电子技术得到高度发展和广泛应用（如空间电子技术、生物医学电子技术、信息处理和遥感技术、微波应用等），它对于社会生产力的发展也起着变革性的推动作用。电子工业是实现现代化的重要技术基础。电子工业的发展速度和技术水平，特别是电子计算机的高度发展及其在生产领域中的广泛应用，直接影响到工业、农业、科学技术和国防建设，关系着社会主义建设的发展速度和国家的安危，也直接影响到亿万人民的物质、文化生活，关系着广大群众的切身利益。
此外，工业生产中为了实现自动控制和调节，也可以利用传感器将非电量转换为电量（信号）。控制利用电能可以达到高度自动化。例如，能控制生产过程或设备，实现程序控制、数字控制或状态控制；能检测生产过程的各种参数，并转换成一定的电信号，实现自动调节和管理自动化。利用电能还能实现巡回检测、分析数据、程序显示、处理故障等功能。所以，电能的应用对劳动生产率的提高和社会生产力的发展起着巨大的作用。
二、电工和电子技术发展概况
现在，人们已经掌握了大量的电工技术方面的知识，而且电工技术还在不断地发展着。这些知识是人们长期劳动的结晶。
