【摘要】 本文利用一个包括光化学反应过程的箱模式,研究了兰州市西固地区光化学烟雾浓度与碳氢类物质和氮氧化物排放量的关系,指出对该地区而言,通过减少碳氢排放量来降低光化学烟雾的浓度是很困难的,有效的途径是减少氮氧化物(尤其是上午)的排放量。更多还原

【Abstract】 A box model for si raulating the atmospheric photochemical pollution in a valley region has been developed and verified by using real source emission, meteodolo-gical and pollutant concentration data for Xigu district in Lanzhou in August of 1983. The model is utilized to study the impact of source density on the photochemical smog concentration.更多还原
