摘　　要：利用SMARTS光谱模式模拟计算出不同大气条件下的直射和总日射光谱辐照度,经硅光电器件光谱响应度加权后,模拟硅器件制作总日射表和直射表的输出。与在同样条件下300～4000nm范围内光谱累计值相比后,得出模拟辐射表的响应度。通过对各种大气条件下相应数值的分析,得出光电总日射表在±5%的误差范围内可用,散射和总日射灵敏度宜分别校准以及直射表则因误差过大而不可用。同时提出,应抓紧研制一种经过检验、可在室内复制的日照阈值标准光源,以便顺利开展自动日照计的校准工作。SMARTS spectral model was used to calculate direct and global spectral irradiance under different atmosphere condition, which weighted by the spectral responsivity of the silicon photovohaic detector, then was used to simulate the output of pyranometer or pyrheliometer made by silicon device. The responsivity of the simulated radiometer was computed by dividing the simulated output cumulative value by the spectral cumulative value in the range of 300-4000nm in the same condition. By analyzing the corresponding data, it is concluded that the photovol- taic pyranometer can be used with error range below ＋ 5%. The sensitivity of diffused radiometer and pyranometer would be better calibrated, respectively. The pyrheliometer was not suggested to use because of its great error. It is urgent to develop a standard light source which had been fully tested and could be reproducible indoors for the calibration of auto sunshine duration sensor.
