风网风向的普遍判别法特征及Kuratowski风网的判别式

THE FEATURE OF GENERAL METHOD AND DISCRIMINANT OF KURATOWSKI NETWORK FOR DETERMINING AIR-FLOW DIRECTION IN UG VENTILATION

研究风网风向判别,既有学术意义,又有实际的应用前景。因此,其普遍判别法引人关注。根据网络拓朴分析,文中提出晋遍风网的概念——完备风网系列,并阐明了它的结构变化规律。于是,得到晋遍判别法的应有特征,其判别式也应有规律,且须与完备风网系列间的结构变化规律相对应。最后,文中完成了Kuratowki风网(即空间基本风网)的判别,为探索普遍判别法创造了一些条件。

It is not only theoretically significant, but practically useful in the future to study the air-flow direction in underground ventilation for thepurposes of stability analysis of air-flow network, thus the general method for determining the air-flow direction is being noticed. According to the topological analysis of network,the author has given a concept of general air-network, the series of complete network, in which the law of structure change is explained. Then, the features of the general discriminant must be relative to the law of structure change. At last, the discriminant of Kuratowski network, (i.e. the basic spatial network)is established and some conditions can be created for solving the general method.
