An energy converter ,also called load (such as a lamp , heating appliance , or electric motor) , converts electric energy into light , heat , mechanical work , and so on. 电源（如源生电池、再生电池和发电机等）将化学能、热能或其他形式的能量转换成电能。

能量转换器 （也称作负载，比如灯泡、取暖器及电机等）将电能转换成光、热和机械等能量2.A.C. circuit analysis involves the addition of harmonic time functions having the same frequencies but different peak values and epoch angles .Direct addition of such functions would call for unwieldy trigonometric transformations . Simpler approaches are provided by the Argand diagram ( graphical solution ) and by the method of complex numbers ( analytical solution). 交流电路的分析包括对有相同频率、不同幅值和初相角的谐振时间函数的加法这些函数的直接相加将要 求用到繁杂的三角转换简单的方法是采用阿尔法冈图法（图解法）和复数方法（解析方法） 。

civilian use 民用 biometric security 生物识别安全系统 security alarm system 防盗报警系统 structured cabling 结构化布线 router 路由器 gateway 网关 ventilation 通风 air conditioning units 空调设备 illumination 照明 electron 电子 heating, ventilating, air conditioning andrefrigeration (HVAC the large-scale integration of electronic systems has reduced the number of components which are used ,leading to an increase in the overall reliability of the system and a reduction in assembly costs . The decrease in size which results from large-scale integration means that the equipment based on microcomputers is usually much smaller,lighter,and more robust than that using older technologies 第一个优点已经提到过了，就是电子系统的大规模集成已经降低了所用的元件数量，促使系统的总体可靠 性的提高和装配费用的降低。

由于大规模集成引起的尺寸减小意味着基于微型计算机的设备功能通常要小 得多，轻得多，并且比用旧技术制成的设备要更为强大6.P116 第一段：Electronic systems are used for handling information in the most general sense.........to store and process numbers. 广义地说，电子系统是用于处理信息的，这种信息可以是交谈、仪器读数或企业账户，但是各种情况 下都涉及相同的主要操作：信息处理、存储和传送在常规的电子设计中，这些操作都是以功能平台方式 组合起来的，例如计数器，无论是电子还是机械的，都要存储当前值，并安要求将该值增 1诸如采用计 数器的电子时钟之类的任一系统要使其存储和处理能力遍布整个系统，因为每个计数器都能存储和处理一些数字7.P117：Microcomputers use RAM (Random Access Memory)......Read Only Memories , EEPROMS . 微计算机常使用 RAM（随机存取存储器） ，在 RAM 中数据可被写入，并且在需要时可被再次读出……所 以称为电可擦除可编程只读存储器 EEPROM。

8.To employ feedback control , we must first measure the condition we wish to maintain at the desired standard . The condition (variable) may be temperature ,pressure ,flow, level , conductivity ,PH ,moisture content, or the like . 要应用反馈控制，我们首先必须测出所要维持的某个期望标准的对应状态这状态（变量）可是温度、压 力、流量、物位、电导体、PH 值、湿度或类似值9.System model can be developed by two distinct methods . Analytical modeling consists of a systematic application of basic physical laws to system components and the interconnection of these components .Experimental modeling ,or modeling by synthesis ,is the selection of mathematical relationship which seems to fit observed input-output data . 系统的模型可以通过两类截然不同的方法来建立。

解析模型是将物理学基本定律系统性地应用于系统各组 成部分及其相互之间的关联关系进而获取结果的方法经验建模，或叫综合建模，是一种通过寻找数学关 系而建立模型的方法，这种数学关系应该能够与输入-输出观测数据相配合PPT 部分部分 1.Typically, a robot system will contain six actuators which are required for full control of position and orientation. 通常一个机器人系统需要六个执行器，这是对位置和方向进行全面控制的需要2.A control system is considered to be any system which exists for the purpose of regulating or controlling the flow of energy, information, money, or other quantities in some desired fashion. 控制系统是任意一个这样的系统：其目的是为了某种期望方式来调节或控制诸如能量、信息、资金等物理量的流动。

3.Intuitively, an adaptive regulator is a regulator that can modify its behavior in response to changes in the dynamics of the process and the disturbances 直观的说，自适应调节器是一类能够对过程特性和扰动的变化做出反应，相应地改变性能的调节器4.The style and feature of design of the new building of Science Hall are introduced in aspects of architecture, structure, water supply and discharge, air-conditioning and weak electricity in this article. 这篇文章从建筑、结构、给排水、暖通(空调)、弱电等方面介绍了科学会堂新楼的设计风格和设计特色 5.Office automation is the term that describes the use of the electronic devices such as computer, facsimile machines and computerized telephone system to make office work more productive. 办公自动化,这个术语介绍。
