排放比 meaning in English

discharge ratio

Major industrial pollutants climbed in the first nine months compared with the same period last year driven by fast economic growth and high emissions of sulfur dioxide , figures from the sepa show
国家环境保护总局称，今年前九个月主要的工业污染随着经济增长和二氧化碳的排放比去年同期有所上升。
When the water dose was 20 % and engine speed was 2000r / min , the maximum fuel saving was 4 . 1 % ; the thermal efficiency of emulsified fuels was higher than that of using pure diesel oil . nox and particulates emissions were reduced greatly by using emulsified fuels . when water dose was 20 % and engine speed was 1500 r / min , the maximum nox reduction was 43 . 4 % ; the average of particulates under all loads was reduced by the extent of 46 % ~ 64 %
结果表明：燃用乳化油节油率有所提高，当n = 2000r min ，掺水率为20时最大节油率可达4 . 1 ；燃用乳化油的热效率也高于燃用纯柴油； no _ x 、颗粒排放比燃用纯柴油时则有大幅度降低，当n = 1500r min掺水率为20时， no _ x排放量下降的最大值可达43 . 4 ；固体颗粒物排放量在整个负荷范围内的平均值比燃用纯柴油时低46 64 ；随着乳化油掺水量的提高，排放效果改善越明显；而thc和co的排放量则比燃用纯柴油时有所升高。
