大气离子 meaning in Chinese
air ion
atmospheric ion
Examples
- 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。 - The air anion bar ' s feature of mount huangshan is : the air ion appraisement coefficient is big , the maximum is 351 . 37 , the single cofficienl of air ion is small , the minimum is only 0 . 09 ; in summer air ion density is high ; when the forest vegetation coverage rate is high ; the area of the natural air anion bar of mount huangshan is not only large , but it " s also distributes to the mountain peak , the distribution area of summit is small
黄山风景区天然氧吧的特征是：空气离子评议系数大，最高达351 . 37 ，空气离子单极系数小，最小只有0 . 09 ；夏季大气离子浓度高；天然氧吧在风景区面积不仅大，而且从山脚至山顶都有分布。黄山天然氧吧的成因主要源于丰富的森林植被、良好的水文条件。
