1、纯电感电压由法拉第定律定义，法拉第定律指出：电感两端的电压正比于流过电感的电流随时间的变化率。因此可得到：ULdidt，式中didt电流变化率，安培秒； L感应系数，享利。

2、三相供电的机械和控制设备与相同额定容量的单相供电的设备相比： 体积小，重量轻，效率高。除了三相系统提供的上述优点，三相电的传输需要的铜线仅仅是同样功率大小单相电传输所需铜线的34。



3、第一个定律指出：在一般运算放大器电路中，可以假设输入 端间的电压为零，也就是说，UU。第二个定律

指出：在一般运算放大器电路中，两个输入电流可被假定为零：II0。第一个定律是因为内在增益A的值很大。例如，如果运算放大器的输出是1V，并且A=100,000, 那么U

因此可设UU105，这是一个非常小、可以忽略的数，U。第二个定律来自于运算放大器的内部电路结构，此结构使得基本上没有电流流入任何一个输入端。

4、简单地说，半导体是这样一种物质，它能够通过“掺杂”来产生多余的电子，又称自由电子（N型）；或者产生“空穴”，又称正电荷（P型）。由N型掺杂和P型掺杂处理的锗或硅的单晶体可形成半导体二极管，它具有我们描述过的工作特性。晶体管以类似的方式形成，就象带有公共中间层、背靠背的两个二极管，公共中间层是以对等的方式向两个边缘层渗入而得，因此中间层比两个边缘层或边缘区要薄的多。PNP 或 NPN(图 1-2B-1)。这两种结构显然是可行的。PNP或NPN被用于描述晶体管的两个基本类型。因为晶体管包含两个不同极性的区域（例如“P”区和“N”区），所以晶体管被叫作双向器件，或双向晶体管。

5、在十进制系统中，基数或底数为10，小数点左边或右边的每一个位都表示其权重增加或减少10的一次幂。在二进制系统中，底数为2，二进制小数点左边或右边的位具有的权重以2的幂次增加或减少。数字可被编码为两个电平的脉冲串，通常标为1或0，如图1-3B-1所示。

6、二进制：1*2^5 + 0*2^4 + 1*2^3 + 0′*2^2 + 1*2^1 + 1*2^0 = 101011十进制： 32+0+8+0+2+1 =43。相反，在把十进制数43转换为二进制形式的过程中，可使其连续被2除。每一次除后所得余数0或1即是二进制数的位数。十进制数43的转化过程：等价于十进制数43的二进制数为101011。

7、十进制数24可被写为八进制数30(3*8^1 +0*8^0)。八进制数字的二进制译码仅需要BCD表中三个最小的有效位，八进制数30的二进制译码为011 000。因为十进制数24用纯二进制形式可写为11000，用八进制译码形式可写为011 000。

8、一个现代的电力系统由六个主要部分组成：（1）电站，（2）升压变压器（将发出来的电升压至传输线所需高电压），（3）传输线，（4）变电站（电压降至配电线电压等级），（5）配电线路，（6）降压变压器（将配电电压降至用户设备使用的电压水平）。

9、这些互联的电网是大型复杂系统，包括被不同组织操控的部分。这些系统可以节约开支，提高整体可靠性，但是也带来了大范围停电的风险。例如，2003年8月14日，美国和加拿大发生了历史上最严重的停电事故。当时，这个区域-1-

61800兆瓦的电力供应中断，五千万人口受到影响。（一兆瓦大约可以满足750居民的用电需求）。停电事件迫切要求更新老化设备，提出关于全国电网可靠性的问题。

10、CUP中央处理单元。计算机系统的核心是中央处理器单元（CPU）。一个典型的个人计算机系统的CPU有三部分：基本存储部分，算术逻辑部分，控制部分。但是这三部分不是个人计算机独有的，它们在所有型号的CPU中都能找到。

11、CAD是这样的软件，可以帮助工程师设计新产品、建筑、印刷线路板、桥梁和机场等土木工程；使他们从绘图等繁琐、累人和费时的工作中解脱出来。当工程师们着手设计时，他们要参考很多的有关结构、零件、材料和辅助材料的手册以作为他们设计的选择。CAD产品将以上内容的手册放在一系列的软件库中，因此可以给工程师提供各种信息，例如，元件、部件、工具和材料的名称、尺寸、功能、性能、规格、形状、颜色、制造商、价格等，所有这些都是工程设计所必须的。

12、CAM是工程师们用于分析产品和项目的软件，它能给出制造或者构造产品或者项目的建议。表示产品形状、尺寸、结构、组成和制造材料的数据、图形和表格等将按软件的需求输入。接着，CAM软件将给出加工的建议，例如，加工程序、加工所用的工具与设备、技术参数（如，公差、加工精度）以及特殊处理过程等。

13、计算机化的通讯。在这一领域的进步始于60年代初，那时的问题是把偏僻地区的计算机终端联入中央计算机。这一问题的解决办法是以异步的、低速的线为基础，或者按星形拓扑结构组成用专线联络每一台终端机，或者以树形拓扑结构用多端线联接多台终端机。到了60年代末，由于出现分布式资源共享网络，这一领域向前迈进一大步。目的是把地理上分布各处的计算机和用户互联起来，使连接到网络中的全部用户都可共享在这些地点开发出来的硬件和软件资源。这些网络的最显著的一个例子就是ARPANET，它是1969年开始实施的一个网络。
