【摘要】 本文通过非线性拟合,给出我国太阳总辐射Q和直接辐射S＇的年值和月值分布的计算公式,年值公式适用于任一地点,月值公式适用于任一月分和任一地点,简化了计算程序。验证结果表明,用这些公式拟合实测Q的累年平均年值和月值的相对误差66站平均分别为4％和5％,拟合实测S＇的累年平均年值和月值的相对误差55站平均分别为6％和10％。因此可用这些公式估算无实测辐射资料地点的上述辐射量。更多还原

【Abstract】 This paper presents four non-linear regression equations about the distribu-tion-of solar energy in China. Two of them (equation (4) and (5) ) are those for the estimation of the monthly values of the global solar radiation Q and the direct solar radiation S’:in equation (5) , (4) and ( 5 )are suitable for any month and any location in China.The homologous equations for estimation the annual values of Q and S’ are.They are suitable for any location in China. In these equations, X1=monthly (or annual) average relative sunshine (in percentage to two places of decimals) ; X2 = altitude of locality (in kilometers) ; X3= monthly (or annual) average absolute humidity (in millibars) ; X4 = days with dust in a month (or (days (with dust in a year) divided by12) ; X5 = days with smoke in a month (or days (with smoke in a year) divided by 12)The examination indicates that: the relative errors to fit the actual normals of Q by using the calculated values of equations ( 6 ) and ( 4 ) , on a average of 66 stations, are 4% and 5%, respectively; for S’, by using equations (7) and ( 5 ) , on an average of 55 stations, relative errors are 6 % and 10%, respectively. Thus, these equations are useful in practice.更多还原
