| 摘 要： | 圆弧法不同于传统的严密平差方法 ,它是把导线的纵、横向闭合差当作系统误差分别进行平差的。通俗地讲 ,就是横向闭合差用角度改 ,纵向闭合差用边长改。实际上 ,是进行两个横向系统之间转换和两个纵向系统之间转换的方法

| Abstract: | The circular arc method is different from the traditional rigorous adjustment method.It takes the longitudional and transverse closures of the traverse line as the systematic error and makes the adjustments saparately.Commonly speaking,it is to correct the transverse closure using the angles,correct the longitudinal closure using the side lengths.Practically,it is the transformation method between the two transverse systems and the two longitudinal systems. |
