A new method, the nodal potential method for discriminating the direction of airflow in a complex network of central ventilation system is discussed in this paper.By introducing a concept of potential field and by giving the calculation of the network sketch a definite physical meaning, the difference of pressure or that of the potential is regarded as a criterion for judging the direction of airflow. The problem of distinguishing the direction of air flow is then converted into one of determining the sequence of the nodal potential series. Based on which principles for judging the direction of airflow in the whole network, the method for comparing the nodal potentials and the preliminary concept of branch parallel translation are put forward, and the precise criterion for some simple networks are derived. In addition, the correctness of the composite determinative method of linear equation is also analyzed.

Calculating different voltage grade networks of magnetic coupling, is used to convert into a voltage grade or standard system of unit. This arcticle suggests a new theory that the conversion is not necessary. It is direct to use real parameters and has got some satisfactory results.
