摘　　要：对兴隆80cmTNT望远镜CCD系统进行了测试和研究。观测了大批Landolt标准星定出了UBVRI宽带滤光片的星等系统转换关系,重点讨论了白光与R滤光片之间的关系,结果表明该系统与标准Johnson系统很接近,白光与R滤光片之间也比较接近。同时测定了兴隆站的夜天光。In this paper, the photometric accuracy of the Xinglong 80cm TNT is studied. The equation to transform observed magnitudes to the standard UBVRI system are established by observing a set of Landoh＇ s standard stars, and the relations between white band and R band is discussed. It is shown that the TNT photometric system is very close to the standard Johnson system. Its white band and R band are also very close. Meanwhile, the sky-brightness values at Xinglong are measured.
