大气气溶胶吸收系数的测量

THE MEASUREMENT OF THE ABSORPTION COEFFICIENT OF ATMOSPHERIC AEROSOL

中文摘要:

      本文讨论了大气气溶胶吸收系数的测量,并介绍了我系根据毛玻璃屏积分法设计的测量系统。根据在北京中关村地区取样观测的结果,在采暖期,气溶胶吸收系数变化于10^-3-10^-4m^-1之间,而在非采暖期,其值约为10^-4m^-1量级。若利用当量碳的概念,则在采暖期当量碳浓度占气溶胶总浓度的50-60%,而在非采暖期,其比例为30-37%。

英文摘要:

      A system for measuring the absorption coefficient of atmospheric aerosol based on the principle of integrating plate has been developed. Measurments in the heating period show that the absorption coefficient of atmospheric aerosols varies in the range of 10^-3-10^-4 m^-1. In the non-heating period, its non-heating period, its value is near 10^-4 m^-1.
