With increased elevationabovesealevel, the flora components of the resource plants present corresponding vertical differentiation patterns.
随着海拔梯度的上升,资源植物的区系成分、性状特征表现出相对应的垂直分异规律。

It is customary to fly , so far as is feasible, at a uniform elevationabovesealevel but within a range of 750 to 1500 ft above the earth's surface.
在条件许可之下,一般都在海拔以上离地面750到1500英尺范围内的均匀高度上飞行。

That is different from the elevationabovesealevel atmospheric pressure and water temperature at 20 degrees centigrade higher than the saturation vapor pressure.
