摘要
采用一维非稳态运动方程对上行风流火灾旁侧支路风流逆转的发生条件及影响因素进行了分析；指出了布德雷克（静态分析）法的局限之处，即没有正确认识到巷道长度及初始风速对风流逆转的影响；进一步阐明了导致这种局限的原因是由于忽略了风流的惯性．
The unsteady state 1 D momentum equation is applied to the analysis of the condition of airflow reversal in parallel airway during a mine five in ascensional ventilation. The limitation of the Budryk’s method(static analysis method),which ignores the effect of the length and the initial airflow rate of a parallel airway on airflow reversal,is pointed out. And it is explained that the limitation is caused by ignoring the inertia of airflow in the static analysis method.
