Water hammer produced by valve opening was studied through an experimental platform which was self propelled in order to study Barometric Pulse Method.
为了更好的研究气压脉冲法，通过自行设计搭建的试验平台，对开阀水锤这种瞬变流进行了研究。

Barometric pulse could cause stronger disordery degree and better flushing effect by comparing the transfer rates of two pressure waves and pressures caused by valve opening and barometric pulse.
Air operated namely USES the air pump and the air valve control air current, the positive governing barometric pressure and the current capacity, enable the air to have the vibration.
