In view of this question the problem is solved via the network dual-export on Linux platform,namely when accessing the education network via the education network export,and accessing the public net via the local ISP export.

The types of interconnection of two-port networks are: series,parallel,series-parallel,parallel-series and cascade connection.

Considering the changes of a power system in topology and on the basis of the two-port network theory, a fast method to calculate the open-port voltage of positive sequence network during a large-scale power system oscillation, which is caused by asymmetrical open-conductor faults, is presented.

tuner or the televisor in VHF band by the theory of Two-port network and filter.

In this paper, the g-parameters of double-port networks in series-parallel connection are deduced, and its application in circuit analysis is introduced.

This paper adopts the theory of two port networks to simplify the sinusoidal oscillating circuit into no power two port networks and describes it with parameter of two port networks.

Aimming at the issue of designing campus network with multiple outputs,this paper proposes centralized,distributed and addressing-mode based distributed routing control model by categorizing customers in multiple outputs network as single direction,double direction and partly double direction addressing mode.

Aiming at the improvement of typical equivalent-circuit model s performance on precision, service band and compatibility with network analysis method, from ac I-V equations, this paper calculated SiGe HBTs two port network parameter model described by scattering parameters.
