air column meaning in Chinese
空气柱，气柱
气柱
Examples
- In wind instruments the sound is produced by a vibrating air column .
管乐器的声音是由振动的气柱产生的。 - Theoretical calculation of air column length of charge structure for smooth blasting
光面爆破装药结构空气柱长度理论计算 - Everything else being equal , a cold air column , because of its higher air density , is heavier than a warm air column and thus produces a higher air pressure
在一般相同情况下，冷空气柱因其密度较高，会比暖空气柱重，因而产生气压较大 - Everything else being equal , a cold air column , because of its higher air density , is heavier than a warm air column and thus produces a higher air pressure
在一般相同情况下，冷空气柱因其密度较高，会比暖空气柱重，因而产生气压较大 - For this reason , everything else being equal , the air pressure which is the weight of air column above a place can vary from place to place on the earth because of the slight changes in gravity
因此在一般相同情况下，气压上空空气柱的重量在地球各地均会因重力稍为不同而有所变化。
