2) politics on reversing
逆转对策
3) airflow reversal
风流逆转
1.
Catastrophe analysis of airflow reversal for descensionally ventilated mine fire;
矿井火灾下行风流逆转的突变动力学分析
2.
A qualitative analysis and computer simulations show that airflow reversal can occur in a non-diagonal airway parallel to the airway on fire in a horizontal ventilation network due to the pressure increase induced by cooling of fume in the airway connected in parallel to the non-diagonal airway but in series with the one on fire.
通过定性分析和计算机模拟发现 :在水平网络火灾中 ,非角联旁侧分支也能发生风流逆转 ,引起逆转的动力是与该分支并联但与着火分支串联的分支中的冷抽力 。
3.
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.
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。
