density of air meaning in Chinese
空气密度
Examples
- The density of air varies directly as pressure , with temperature being constant
温度不变，空气的密度与压力成正比。 - Looking at the lift formula , you can see thatlift and drag vary directly with the density of air
你只要看一看升力公式就可以了解升力和阻力与空气密度成正比。 - The daily change law of air ion is : the density of air ion in morning is the highest , it falls at noon or in the afternoon . while it raises again in the dusk . ( 2 ) in summer , the density of air anion in songgu and diaoqiao scene district is more than 30000 / cm3 , while in yungu scene district and bailongtan , renzipu of wenquan scene district it is 10000 / cm3 . in beihai it reachs 18000 / cm3 , the density is not well - distributed in xihai , yupin and tianhai , it presents a kind of jumping change ; ( 3 ) the air anion density in winter is small than 1000 / cm3 only at yiranting , taoyuan square of wenquan and yupinglou
大气离子日变化规律是：清晨最高，正午或午后降低，傍晚又比较高； ( 2 )夏季，松谷景区和钓桥景区的负离子浓度均在30000个cm ~ 3以上，而云谷景区和温泉景区的人字瀑和白龙潭测点负离子浓度在10000个cm ~ 3以上；北海景区负离子浓度在18000个cm ~ 3以上，西海、玉屏和天海三景区的负离子浓度分布不均匀，呈现一种跳跃性变化； ( 3 )冬季负离子浓度只有温泉景区的翼然亭、桃园广场和玉屏楼的负离子浓度小于1000个cm ~ 3 ，其它地方的负离子浓度均大于1000个cm ~ 3 ； ( 4 )全风景区中以松谷和钓桥景区的负离子含量水平高，而且它们在春季负离子含量也超过8000个cm ~ 3 ，具有治病的功能；温泉景区的人字瀑和白龙潭测点负离子浓度春季超过16000个cm ~ 3 ； ( 5 )整个风景区的负离子含量均大于正离子含量，用单极系数q和空气离子评议系数ci评价，各景区的q 1 ， ci 1 ，高于最佳空气清洁度的指标。 - Natural air anion bar is negative ion enriched district . as tour function district , it has health protection , and recuverate effect . according to the result of medical research , the author consider that the average density of air anion in higher season should be more than 8000 / cm3 , in lowest season it should be more than 1000 / cm3
天然氧吧是负离子富集区，作为旅游功能区，具有保健、疗养的功效，参照医学研究的结果，作者认为空气中负离子浓度在高值季节，平均浓度应达到8000个cm ~ 3以上，在低值季节应在1000个cm ~ 3以上。
