Study on Correlative Branches which Affect the Stability of Diagonal Branches
Jinzhang Jia · Journal of Liaoning Technical University · 2002
Based on the analysis to current mathematical model of diagonal branches automatic identification, by using the method of graph theory and set theory, a further study is performed, a serial of new concept correlative to the stability analysis of diagonal branches, such as key influence branch and non-key influence branches of diagonal branches, are put forward. A mathematical model to determine key influence branches and non-key influence branches is given, an example analysis is presented, which provide the foundation for further research in the stability of diagonal branches. The determination of key influence branches and non-key influence branches is important in the aspects of daily ventilation management, one-ventilation and three-prevention, the reliability of ventilation system, airflow control during fire period and ventilation reform.
