| 摘 要： | 在电子线路中，对放大电路的负载而言，放大电路可以等效处理为一个具有内阻的信号源，其内阻称为放大电路的输出电阻，它的大小反映放大电路带负载的能力．文章中讨论了一种不再含有受控源，可直接应用电阻的串、并联公式确定放大电路输出电阻的方法——缩减定理法．

| Abstract: | In the electronic circuit, as far as the load of the amplification circuit is concerned, the amplification circuit can be equivalent to a message source which has an internal resistance. This internal resistance is called the output resistance of the amplification circuitic, whose magnitude reflects the ability by which the electron circuit drives the load. This paper discusses a kind of method which does not have any controlled source, but it can directly use the formula of series or parallel resistance to confirm the output resistance of the amplification circuit - Curtailed Theorem Method. |
