摘　　要：水准仪i角的检验和校正是一项非常重要的工作。在修订后的国家规范中新规定的i角检验和校正的I1ABI2方法,与旧方法相比较,增加了检测现场布置的距离要求以及两差改正的计算,使得该项的检验更加合理、科学、精确。但是,有些测量员由于长期应用旧的方法,对新方法还无足够的认识和理解,在实际测量工作中仍在沿用旧方法。为此,对新的检校方法进行解读。It is very important that calibration of I1ABI2 method for level i-angle. To increase the correction for effect of earth curvature and refraction, as compared with old method in national standard about level i-angle I1ABI2calibrating method, to make it more rational, scientific and precise. Due to surveyor with old methods in long term, some don＇t e- nough recognition and understand, thus as usual continue to use old methods in real surveying. For this reason, it is in- terpreted, analyzed and discussed in this paper.
