摘要
本文介绍了总日射表倾斜效应测量装置的各有关系统、调试和数据处理方法,并论证了其合理性和可靠性。采用了微机控制的自动采集系统,提高了测量质量,大大扩展了研究范围。在一年多的研究期内,先后共收集了各种测试数据近60万个,对国产的4种仪表进行了多方面的探讨,也对部分国外仪表进行了研究。首次发现了倾斜效应的方位影响和倾斜效应有随辐照水准增加而增强的趋势。明确了全黑型仪表的倾斜效应低于黑白型的规律,用黑白型仪表做倾斜测量时,应事先做好定方位定倾斜的校准。
This paper presents in detail the composite systems of experimental apparatus on the inclined effect of pyranometers,and the methods of their adjustment,measurement and data treatment are also introduced.The rationality and reliability of the methods are discussed and demonstrated.Due to the adoption of micro-computer to collect experimental data automatically,not only the precision of measurement is significantly improved,but also the quality and range are highly enhanced.About 600 thousands of experimental data have been collected during one and half a year.Four types of pyranometers manufactured in our country and several foreign ones(e.g.PSP and 8-48) are studied.Besides,two additional effects are discovered for the first time,one is the azimuthal effect,and another is the effect of insolation.It is confirmed that the inclined effect of black- body type is weaker than that of white-black type,so the calibration of inclined and azimuthal effects should be performed beforehand,providing that white-black type pyranometers are used.
