（p＋q）端口回转器及其群特性

本文提出了一类多端口电阻元件－（ｐ＋ｑ）端合回转器，用群论的方法研究了所有（ｐ＋ｑ）端口回转器与变压器构成的集合ＧＩＴ（ｐ＋ｑ）。结果表明，当ｐ＝ｑ＝ｎ时，ＧＩＴ（２ｎ）构民群，同时还讨论了（ｐ＋ｑ）端口回转器的分解，电路实现方法和应用。

(p+q)-Port Gyrator and Its Group Character

In this paper,(p+q)-port gyrator that is a kind of multiport resistor element is presented.The set GIT(p+q)of all (p+q)-port gyrators and transformers is studied by the method of group theory.The results show that the GIT(2n) forms a group when p=q=n.Finally,the decomposition,circuit synthesis and application of (p+q)-port gyrator are discussed.
