| 摘 要： | 1987年9月在重庆远郊四面山与市区观音桥同时进行了SO_2的对比测量.资料分析表明:(1)晴天时四面山SO_2日变化呈三峰三谷分布,峰值都为13—14ppb,分别在05:00,11:00及18:00时,而夜间的SO_2几乎都接近0ppb;市区观音桥的SO_2日变化呈双峰双谷分布,主峰在08:00时左右出现,浓度值达425ppb.(2)降雨条件下,四面山SO_2全部被清洗,接近0 ppb,市区的SO_2也受到明显冲洗.(3)四面山SO_2日平均浓度为2ppb,而市区观音桥日平均浓度为120ppb,市区的S

| Abstract: | For comparative study of SO2 in Chongqing area , measurements of SO2 were conducted simultaneously at Guanyinqiao in the suburb of Chongqing City , and at Simianshan, a mountainous region 90km south to the chongqing city during September 1987. The measured results indicate that: 1 . In sunny days diurnal variation of SO2 concentration at Simianshan is a three-mode curve, while at Guanyingqiao is a two-mode curve; 2. In rainy days SO2 in the city is greatly washed out by precipitation while at Simian shan SO2 is completedly washed out with the concentation remaining at 0 ppb; 3 . During the measurements, the concentration of SO2 during night at Simianshan is 0 ppb or so and the average concentration is 2 ppb, while in the city the average concentration is 120 ppb or so , which is 60 times as much as that in the mountainous area . |
