【摘要】 根据全国主要城市冬季各月典型日水平面上的太阳总辐射强度和散射辐射日总量,计算出全国主要城市冬季各月典型日大气透明度和水平面上的散射辐射强度与垂直于太阳光线平面上的太阳直射辐射强度之比,进而计算出全国主要城市冬季各月典型日水平面和各朝向立面各时刻的直射辐射、散射辐射和总辐射强度.更多还原

【Abstract】 For lack of direct and scattering solar radiation intensities in current "Table Solar Radiation Intensities of Major Chinese Cities in Winter", hiemal atmospheric transparencies and ratios of scattering solar radiation on the horizontal to direct solar radiation on the plane that was perpendicular to the light beam are calculated from the total and scattering solar radiation intensities on the horizontal. And direct, scattering and total solar radiation intensities per hour in major Chinese cities in winter are calculated using the calculated atmospheric transparencies and the ratios. In comparison with the data calculated using the cosine rule from the existing table, the results have a higher precision.更多还原
