【摘要】 １９９６年１－２月，我们用光电方法测定了丽江高美古在Ｂ、Ｖ两个波段的大气消光系数。为便于比较，在同一时期还测定了云南天文台凤凰山台址的大气消光系数。本文给出了观测结果，同时也列出了世界上一些天文台站的数据以供参考。更多还原

【Abstract】 Extinction coefficients at Gaomeigu, Lijiang have been measured in B and V bands by using the photoelectric method during Jan-Feb 1996. For the convenience Of comparison, the measurements have been also made at the Yunnan Observatory in the same Pened of time. All results are presented in this paper. Data from some observatories around the world are also presented for comparison.更多还原
