News Release 23-Jul-2018 美国东部冬季的硫酸盐与硝酸盐 Peer-Reviewed Publication Proceedings of the National Academy of Sciences 一个再现了美国东部冬季观察到的硫酸盐、硝酸盐与铵颗粒浓度的大气化学模型提示，随着二氧化硫（SO2）与氮氧化物（NOx）排放减少，这些前体在冬季转化为硫酸盐和硝酸盐的效率增加，因此抵消了排放减少对硫酸盐和硝酸盐浓度的效应，它还提示，与当前的减排速度相比，改善冬季空气质量可能需要让减排加速。 ### Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
