摘要
我们考虑一个单端口，不一定是线性的，在其端口处出现一个受控源。该源的控制完全在单端口内部。如果该源是并联电压源，则其等效电路为理想独立电压源；如果它是串联电流源，则其等效电路为理想独立电流源。（与通常一样，“理想”源定义为其提供的函数不依赖于负载的源。）在简单的LTI（线性时不变）情况下，这些结果可以分别通过在戴维南等效中令RTh为零，或在诺顿等效中令RN为无穷大来获得；然而，最终电路不包含任何线性元件这一事实表明了将其推广到非线性单端口的可能性。对电路结构（其中的函数依赖关系）存在一些限制，而这些限制的清晰性，即单端口对于任意负载成为理想源的条件之清晰性，正是其美学要点。

备注
The text is very close to our publication in Far East Journal of Electronics and Communication vol. 5(2), 79-89 (2010). We are concerned with the question of whether or not a circuit (one-port) can be considered as an independent ideal source of voltage or current. This is around Thevenin's (Northin's) theorem that was, in fact, first proved by Hermann von Helmholtz. 11 pages, 6 figures
