| 摘 要： | 根据矿内空气非定常流动方程，分析了均匀管道的简谐振荡特性和周期压力阶跃脉冲在无限大管道与终端放空管道的瞬态特性，通过现场实测与分析，得出有扰动源引起井巷风流脉动时，流动变化不大而压力振幅较大且压力振幅在传播过程中基本不变的结论。

| Abstract: | According to the unsteady flow equation in mine ventilation, properties of simple harmonic oscillation in a uniform duct and transient characteristics of step pulse of periodic pressure in an infinite duct and in a open-terminal duct are analyzed. Field tests and analysis indicate that there are less variation of velocity and greater variation of pressure in an airway, and pressure amplitude keeps approximately invariable in a propagation process when pulse airflow is induced by disturbances. |
