摘要
介绍了先求定向角γ和连接角δ,进而计算多边形内角和闭合差的粗差检验方法。通过大量实例证明这种方法是完全可靠的。
The paper introduces the method of error check, of which calculate directional angler and connecting angle, and calculate polygonal inner-angle and error of closure. The great deals of concrete examples proved that the method is completely reliable.
