摘　　要：文中从初等平面几何的观点剖析了附合导线方位角闭合差计算公式中隐含的几何意义,给出了计算n值的理论公式。公式的提出使得对n的定性描述变成定量确定,大大方便了程序的编写,使公式更易于理解和掌握。From the point of view of the primary plane geometry, the authors of the paper have investigated the geometric meaning of the formula used for computing the closed error of the azimuth in the closed connection traverse, and put forward a formula to determine the integer n used in the formula. Good results have seen in helping the surveyors to understand the meaning of the formula, so do in the mastering office skills in the traverse computing.
