摘　　要：近年来,大部分工程测量控制网都由电磁波测距导线代替了传统的三角测量,但如何衡量导线测量的精度,用传统的全长相对闭合差,它没有考虑到估算标准偏差(偶然误差)和导线几何形状的影响。本文推荐采用数理统计中x^2检验来确定所测导线闭合差是否被接受,为了计算方便,还编有简单的计算程序。In recent years, the Tellurometer traverse is widely used for engineering control net instead of traditional triangulation. But it is not so perfect because only whole-length relative misclosure is used to evaluate the precision of traverse, and it does not take the effects of standard deviation and traverse geometry into account. In this paper, Chi-square(X^2) test is adopted to make it up.
