对于线性非时变的无源二端口网络，在零初始条件下，若存在互易性及对称性，则其电路参数具有一定的特殊性。

If reciprocity and symmetry exist for passive two port networks of linear time invariant under zero intial condition, the circuit parameters will have some important characters.

对于含有线性受控源、或独立电源的电路，当电路结构和元件参数满足一定条件时，也同样具有互易性。

For the circuit including linear controlled source or independent source, it also has reciprocity when the circuit constitution and element parameter satisfy some conditions.
