摘要
文章介绍了车载粒子探测系统所使用的设备、显示分析软件以及 2 0 0 0年 6月和 12月在北京市城市污染大气探测中获取的数据。探测结果表明 :北京市夏季和冬季近地面悬浮粒子浓度存在较大差异 ;同一季节北京城区及周边地区近地面悬浮粒子浓度存在较大差异 ;同一地区同一季节白天与黑夜存在较大差异。车载探测系统的观测试验表明 :该套车载探测系统能连续记录近地面粒子尺度、汽车行驶轨迹和速度 ,其测量频率高 ,机动灵活 ,不受天气条件的影响 ;增加光阵探头个数 ,可以对 0 .1～ 930 0 .0 μm的雾、气溶胶、雨和雪等粒子进行测量 ;可较好地应用于地面污染监测 ,同时还可用于云雾人工影响天气作业的地面监测。
The vehicle-based particle measuring system, software and observing data of urban air pollution in Beijing in Jun. and Dec. 2000 are introduced. The observing results show that there are big differences in the concentration of particles in near ground air in summer and in winter, in urban area and in suburb area and the concentration of particles in near ground air has an obvious change from day to night even in the same area, the same season. The experiment of monitoring urban air pollution indicates that the vehicle-based measuring system can record the size and concentration characteristics of particles in near groundair, the traveling track and the velocity of the vehicle.
