| 如果两只管子是同极性的（例如都是NPN），那么前一个管子的基极为复合管的基极；两管集电极相连，为复合管的集电极；前管的发射极连接后管的基极；后管的发射极为复合管的发射极。这种组合的放大率为： If the two tubes are of the same polarity (e.g. both NPN), then the base of the former tube is the base of the composite tube; the two collectors are connected to form the collector of the composite tube; the emitter of the front tube is connected to the base of the rear tube; and the emitter of the back tube is the emitter of the composite tube. The magnification of this combination is: β = (β1 + 1)×β2 + β1 Beta=(beta 1+1)*beta 2+beta 1 如果两只管子极性不同，则前一个管子的基极为复合管的基极；前管的集电极与后管的基极相连；后管的发射极为复合管的集电极；前管的发射极与后管的集电极相连，为复合管的发射极。这种组合的放大率为： If the polarity of the two tubes is different, the base of the former tube is the base of the composite tube; the collector of the front tube is connected with the base of the back tube; the emitter of the back tube is the collector of the composite tube; and the emitter of the front tube is connected with the collector of the back tube, which is the emitter of the composite tube. The magnification of this combination is: β = β1×β2 + β1 Beta = beta 1 x beta 2 + beta 1 复合管的极性有前管决定，即前管为NPN则复合管就是NPN。 The polarity of the composite tube is determined by the front tube, that is, the composite tube is NPN if the front tube is NPN. 复合管的主要优点是可以获得极高的电流放大倍数β。 The main advantage of the composite tube is that it can obtain very high current amplification factor beta. |
