电子专业英语lesson4-Diode and Transistor(1)

• It should be noted that the polarities of bias voltage for an NPN transistor differ from those of a PNP transistor; however, the net results are the same. • For example, as shown in Fig.1-4, the emitter is negative with respect to the base(NPN) to produce a forward bias. • In Fig.1-4, the emitter is positive with respect to the base(PNP) to produce the same forward bias.
• This is done by adding a second junction to the basic diode junction, discussed in the above section. • For this reason, such transistor are called twojunction transistors or bipolar transistors. • The author prefers the former term but recognizes that the latter term is also in common use.
['kæ θəud] 阴极
• Usually, when such semiconductors are used with signals, the semiconductors are called diodes or signal diodes. • When the device is used for conversion of alternating current to direct current, the semiconductor is called a rectifier.

第三课晶体管及其基本电路
现在，晶体管是电子技术中最重要的器件。它们不仅作为独立元件，而且在集成电路微薄的硅片上可包含成千上万个晶体管
晶体管由3层半导体材料构成:一种类型的薄层在中间，两边分别是另两种类型。可以有两种排列方式:N型在中间，P型在两边(PNP); P型在中间，N型在两边(NPN )。中间层称为基极，两边外层分别称为发射极和集电极(如图1-17所示)
电子信息是当今国内外发展最迅速、技术更新最快的工程领域之一，电子信息专业英语对学习电子信息新知识和新技术起着非常重要的作用。

（3）电感电感是由绕成线圈形状的导线组成（图1.3）。当电流通过线圈时，在线圈周围将产生磁场，它将阻止电流强度的快速变化。像电容一样，电感可以被用于分辨信号变化的快慢。当电感和电容连在一起使用时，电感上的电压在一个确定的频率上达到最大值。这一原理用在无线接收机上，通过调节可变电容可以选择一个特定的频率。（4）晶体管晶体管由半导体制成。半导体是硅和锗这样的材料，经过搀杂（即加入微量的外部元素），使内部的自由电子过剩或者不足。前一种类型的半导体叫n型半导体，后一种类型的半导体叫p型半导体。将n型半导体和p型半导体结合在一起就形成了二极管（图1.4a）。当这个二极管连接上电池，使p型材料为正，n型材料为负时，因为 p区缺少电子，电子就会被电池的负极排斥而毫无阻止地进入p区。当电池反接时，要到达p区的电子经过n区非常困难，因为n区已经填充了大量自由电子，电流几乎为零。1948年发明了双极的晶体管（图 1.4b），它由三层搀杂材料组成，两个p-n结可以配置成p-n-p或n-p-n 型晶体管，其中一个p-n结连接上电池使其有电流通过（正向偏置），另一个p-n结以相反的方向连接上电池（反向偏置）。如果用一个外加信号使晶体管的正偏p-n结中的电流发生变化，反偏p-n结中的电流将相应地跟着变化。这个原理可以用来构建放大器，正向偏置p-n结的小信号可以引起反向偏置p-n结中电流大的变化。

• The open—loop control system does not provide positioning feedback to the control unit.
• The closed—loop control system is very accurate. It has an automatic compensative function for error, since the feedback device indicates the error and the control makes the necessary adjustments to bring the slide back to the position. They apply AC, DC or hydraulic servomotors.

tools are used to produce a part. The tools must be replaced quickly for the next machining operation. For this reason, the majority of NC／CNC machine tools are equipped with automatic tool changers, such as magazines on machine center and turrets on turning centers. They allow tool changing without the intervention of the operator.
