摘要
本文是通过10个月的日射、日照资料对比观测、统计的乔唐、康氏和光电式日照计记录阈值的平均值和标准偏差,分析了乔唐日照计进光孔径、涂药方式对感光迹线的影响,测定了感光药的吸收光谱,并根据日出日没时直接日射辐照度的平均变化率,估算了由阈值的不确定度引起的日照时数的误差,从而为我国几十年的乔唐日照资料的评价提供依据。
With 10-month comparative measurement of solar radiation and sunshine, the arithmetic means and standard deviations of threshold of Jordan. Compbell-storkes and photo-electric pattern sunshine recorders obtained. The effect of sensitive trace for aperture and chemicals-usage in Jordan and the absorbent spectrum of sensitive chemicals are also tested and analysed. Based upon the mean rate of solar irrandiance at sunrise and sunset, the errors of sunshine duration from uncertainty of threshold are calculated. It provides basis for evaluation of our several decades Jordan sunshine data.
