This paper mainly dealt with the feasibility, extent of application and affecting factors of oxygen consumption in indoor air (OC). It was indicated that OC in indoor air was chiefly related with human actiwity, smoking and stink resources and highly correlated with CO, CO_2 and NH_3 in indoor air pollution. The results showed that OC in atmosphere and cleaning indoor air as well as polluted indoor air were 6.13±0.53, 4.06±0.44 and 15. 61~28. 30mg/m~3, respectively. It was confirmed that OC could be applied...

In this paper, the aerosol data and radiative data of Lanzhou and Beijing are used. The diurnal variations of imaginary part are determined by using radiative observational data and radiative model for the clean sky according to parameterization method of the ratio of the aerosol absorption and back scattering which was proposed by Robinson. Compared with the values calculated from the element carbon content of the East Asia atmospheric monitoring net they are in good agreement. The diurnal variation of imaginary part is that after sunrise the imaginary part is the largest and it reaches the minimum in the afternoon and after sunset it increases again.
