摘　　要：结合实例分析了闭合导线测量中边长加常数粗差对导线闭合差的影响规律,从理论上证明了边长的比例误差不影响闭合导线的闭合差,并说明了导线的方位角闭合差和相对闭合差作为限差的不可靠性,指出了闭合导线测量中应当注意的若干问题。This paper discusses the effect of adding constant errors about the distance in closing traverse, it is proved theoretically that the proportion error of distance have not impacted the closing error of closing traverse, and explains the fallibility which azimuth closing error and relative closing error of traverse is viewed in the light of the allowable error, finally the author points out several points in measuring closing traverse.

关 键 词：闭合导线 闭合差 加常数 比例误差
