| 摘 要： | 本文研究了自由网平差中近似坐标的计算方法，在此基础上分析选用不同近似坐标对自由网平差结果的影响。表明选用不同参考系的近似坐标，仅影响计算的迭代次数，并不影响变形监测数据的严密平差结果。

| Abstract: | This paper first introduced the approximate coordinates＇ calculation methods in the free network adjustment, and then estimated the affection of approximate coordinates in free network adjustment. This study shows that the different references of approximate coordinate have effect on the number of iterations, but do not affect the precision and reliability of the adjustment results. |
