However, when the fire happens, the downward ventilation can often cause the air disorder and airinversion easily.
但下行通风在发生火灾时往往会引起风流紊乱，容易造成风流逆转。

Based on the formation of inversion weather in Erdous plateau, the temporal and spatial distribution of air pollution and feasible approach to control the pollution are discussed.
The volumetric heat transfer coefficients H_v between porous aluminum and air were measured by developing single-blow transient experimental technique in conjunction with the inversion analysis.
