It deeply affects our students, and this makes colleges and universities strengthen the construction of network position.

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 Localization Technology Based on TDOA for Wireless Sensor Network Nodes;

According the speciality of wireless sensor network technology and alarming in intelligent home,we designed an alarming system based on wireless sensor network technology,built the structure picture of alarming system,and designed the network node and software of the alarming system.

Such design enhances the flexibility of the system and improves the reliability of the network nodes.
