Regardless of type NPN or PNP-type tubes, the internal transistor has three areas, namely, the launch area, base, collector area, the three areas form two PN junction. 无论NPN型还是PNP型管,三极管内部均有三个区、即发射区、基区、集电区,三个区形成两个PN结。
The region in a transistor between the emitter and the collector. 晶体管中发射极和集电极之间的区域。
Therefore, if we have a way of holding emitter current constant through a transistor, the transistor will work to regulate collector current at a constant value. 于是,只要我们能让晶体管的发射极电流保持恒定,它就能保持发射极电流为恒定值。
Remember, the transistor's collector current is almost equal to its emitter current, as the α ratio of a typical transistor is almost unity ( 1). 不要忘了,通常典型晶体管的系数α乎是1,因此晶体管集电极电流与发射极电流也几乎是相等的。
For example, a transistor is a controllable switch, but it is directional between the collector and emitter, and it has interactive control between the base and emitter. 例如,晶体管是可控的开关,但它在集电极和发射极之间是定向的,并且在基极和发射极之间是配合控制的。
We've seen already how maintaining a constant base current through an active transistor results in the regulation of collector current, according to the β ratio. 我们已经看到有源晶体管的恒定的基极电流是如何以系数β制集电极电流的。

Under the state of optimum operation of the amplifier, the following basic amplifier parameters are determined: the waveforms of the collector current, the collector-to-emitter voltage, the instantaneous power dissipated in the transistor, the collector efficiency, and the values of the load-network components. 在最佳工作状态下,确定了放大器的集电极电流和集电极-发射极电压波形、晶体管的瞬间能量损失、集电极效率和负载网络参数。
Its configuration is similar to a conventional transistor with the exception of the addition of a v or π layer ( transition region) between collector and base regions and it is operated as a diode. 除在收集结与基区之间插入了一个v型或π型渡越区外,器件的结构与通常晶体管的很相似,但它是作为两端器件运用的。
