Wind direction, wind velocity, air temperature and air pressure have a very great effect on the propagation of pressure waves . 風(fēng)向、風(fēng)速、氣溫和氣壓對(duì)壓力波的傳播有十分巨大的影響。
The growing and collapsing of gas bubbles and cavitation not only damage the flow continuity and reduce the working mediums physical performance , but also influence the propagation of pressure pulsation 氣泡和氣穴的產(chǎn)生及破滅不僅破壞了流體的連續(xù)性、降低了介質(zhì)的物理特性,而且還會(huì)影響壓力脈動(dòng)波的傳播過(guò)程。
