日平均浓度 meaning in English
daily mean of concentration
Examples
- In 2007 , the average daily fine particulate concentrations were significantly lower than would have been reported if the stations in traffic areas continued to be used
2007年，如果仍采用从城区那两个机动车污染监测站收集的数据，那么可吸入颗粒物的日平均浓度会大大高于政府正式公布的水平。 - This improvement equals nearly 10 % of the average daily fine particulate level , and is far larger than the minor improvement reported in fine particulate concentrations between 2002 and 2006
这种“改善”相当于可吸入颗粒物的日平均浓度降低了近10 % ，远高于政府公布的2002至2006年期间可吸入颗粒物日平均浓度的改善幅度。
