Then it will affect the plume's ascendingvelocity and the temperature drop scope in the plume rise process.
并对燃烧后的烟气羽流的上升速度，羽流上升过程中温度下降幅度产生不同的影响。
2
The expanding velocity of its radius reached the minimum when the ascending or descending velocity was in the maximum and vice versa.
上升下降速度最大时半径膨胀速度最小，而上升下降速度最小时半径膨胀的速度最大。
3
The results indicated that the extraction system had a higher extraction velocity in the moment of globelet formation than that during the process of globelet ascending.
