汉英语境1


英译术语:

annual mean value concentration


汉语语境:

能见度的恶化主要与细粒子关系比较大,PM10有一半年份的年均值浓度超过国家二级标准的年均值限值( 70 μg·m^- 3),而全部年份的PM2. 5年均值浓度都超过国家二级标准的年均值限值( 35 μg·m^- 3),尤其是有些年份的年均值浓度超过标准限值的 2 倍,细粒子浓度甚高。


英语语境:

The deterioration of visibility had much to do with fine particle pollutions. Half of annual mean value concentrations of PM10 exceeded the mean critical value ( 70 μg·m^-3) stipulated in national grade 2 standard, while all of the annual mean value concentrations of PM2.5 exceeded the mean critical value ( 35 μg·m^-3) of national grade 2 standard. Some annual mean value concentration of PM2.5 are even over twice of the standard value, indicating high fine particleconcentrations.
