气密度 meaning in Chinese

air tightness

The drag force decreases as the air density decreases .
当空气密度减小时阻力也减小。
Vapor density ratio
蒸气密度比
On the saturate concentration , the moisture density in the micro - holes was 100 times larger than the vapor density in the standard state , but only 8 % of liquid water . the water inside the plastic material was in a special liquid state . the delamination and the delamination recovery were observed by c - sam
当水汽浓度达到饱和时，在塑封材料中可以被水分子进入的有效体积内，实验条件下的水汽密度为标准状态下水蒸气密度的100倍，为液态水密度的8 ，表明在塑封材料中的水分子以一种特殊的液态水形态存在。
