摘　　要：构建了无定向导线的一般形式,提供了无定向导线在3种坐标系中方位角的计算方法和转换方法,对无定向导线条件方程的问题进行了深入地研究,找到了建立无定向导线条件方程的最佳方法,依据无定向导线的自身规律,推导出了一套完整的实用计算公式,建立了无定向导线条件平差的具有可操作性的数学模型.This paper constructed the general form of nondirective traverse,provided the calculational and converting method of azimuth in three kinds of coordinate system,and found the best method for listing condition equation based on in-depth research for problems of nondirective traverse condition equation.According to the nondirective traverse's rule,a set of practical formulas was obtained,and established the mathematical model which is operated.

关 键 词：数学模型 条件平差 无定向导线
