摘要
根据振荡流体力学理论，在一般湍流通风时井巷断面风速分布规律的基础上，分析探讨了脉冲通风时巷道断面上的风速分布规律，从理论上进一步证实了脉冲通风会增强风流中湍流强度效应。
Based on the oscillatory flow mechanics,discusses the law of the air velocity distribution of a roadway section when pulse ventilation occurs.It is proved that this kind of ventilation increases the pulse strength of air folw.
