摘　　要：１９９３年冬季，在兰州西固地区利用热电式相对日射表和８种有色玻璃滤光片进行了分光辐射测量。根据这次观测资料，利用简化的辐射传输方程和Ａｎｇｓｔｒｏｍ公式计算了气溶胶的光学厚度和大气浑浊度，分析了大气浑浊度和太阳辐射特征及它们之间的相互影响；同时讨论了利用Ａｎｇｓｔｒｏｍ公式计算大气浑浊度时存在的一些问题；最后还讨论了大气质量。By means of thermoelectric actinometer mounted with eight kinds of the light filter,the spectral intensities of the solar direct radiation were measured over the Xigu district of Lanzhou city in winter Based on these observation data,aerosol's optical depth and atmospheric turbidity were calculated by using simple radiation transfer equation and Angstrom formula, and the characteristics of the atmospheric turbidity and solar radiation as well as the interaction between them were analysed further At the same time, we discussed some problems in the turbidity calculation by using Angstrom formula Last,the effects of the air mass, atmospheric trubidity and water vapor on the relative fluxes of the solar spectral radiation were also discussed
