Then, a supersonic air flow generator for triggering ice crystals generation in supercooled fog is designed.
然后设计了超声速气流发生装置并在过冷雾中进行触发冰晶产生的实验。

Based on a lot of experimental analysis and field tests, the states of bubble flow, plunger flow, ring film flow, fogflow lied in gas-water phases in wellbore are summarized.
