摘要
通过对各种型号的总日射表的研究,发现被测总日射表的预热时间不同对测量结果有很大的影响。这被称之为总日射表的热稳定时间。并建议凡用总日射表测量时,应等待5分钟,更精确的测量工作甚至应延长到10—20分钟。
The study of different patterns of pyranometers is made.It is found that different preheatingtime of pyranometers would appreciably affect the results of measurements.It is called thermalstable time.Thus,it is suggested that any measurement is made by pyranometers,it should take atleast 5 minutes to preheat,and even 10 to 20 minutes for more accurate and precise measure-ments.
