摘　　要：半不定网络常常用来模拟浮地阻抗和浮地网络。本文在线性、时不变网络的范围内探讨了N—端口网络的半不定性,并给出了判别由浮地的无源元件、受控源、零极子对(nullor)以及理想运放所组成的网络为半不定的定理和推理,文中还给出其应用举例。Semi—indefiuite networks have been often used for the simulation of floating immittances and flooting networks. In the paper, the semi—indefinite properties of linear time—imvariant n—port notworks are researched, some theorems are given about semi—indefinit networks, which contain floating passive elements, controlled sources, nullors and ideal Op amps. some opplieations of the networks are also dscussed.
