First of all,this paper describes route selection behaviors of passengers and the characteristics of city traffic networks,and then presents the public traffic network-transit matrix based on key stops.

calculating signal determinant by decomposingnetwork matrix is presented.

Under the conditions of a comprehensive temperature outside the room known as tz (τ) and the temperature inside the room known as t 0 , this paper derivated a formula calculating the heat amount conducted from both the single shield of wall body having inner and outer air shields and the wall body having multishields, through the use of network matrix, which enables to compute with computers.

According to the basic principles of hydromechanics and the electrical network theory, a new method named network matrix approach is presented in this paper to calculate ventilation system.

The switch matrix network composed of severals witch arrays is used to complete the automatic access between the radio channels and wire channels.

The influence of urban rail network on public traffic is analyzed by using relevant theories of complex networks and the real data of Beijing public traffic network.

Finally,we establish a cost formula about public traffic system,and bring forward a solution of shortest path of public traffic network.
