证明了(p+q)端口变压器当p=q=n时的2n端口变压器集合IT(2n)构成群,在此基础上,利用子群一陪集的概念导出一类基本多端口电网络元件——(p+q)端口回转器,并且用电路实现了(p+q)端口回转器,证明了(p+q)端口回转器实现现有电路元件具有很强的优越性,证明了(p+q)端口回转器是基本多端口单元元件。
The set of 2n-port transformer, which is the special set of the (p+q)-port transformer when p =q=n, can form group is proved. Based on it, multi-port network element ((p+q)-port gyrators) is deduced by using subgroup and coset conception; and (p+q)-port gyrator is realized with circuits. It is proved that the (p+q)-port gyrator has great advantage in realizing circuit element; and (p+q)-port gyrator is the basic multi-port unity element.
