在闭合导线内业计算中，由于连接角没有检核条件，因而对连接角未进行改正。
In office calculation of closed traverse, the Angle of connection is not corrected, because there is no check condition.
这样，可以检核闭合导线测量的粗差和提高它的精度。
Like this, it can check the mistake and increase its precision of closed traverse's measure.
闭合导线测量时，有时会出现一种假闭合现象。
When surveying the closed traverse, sometimes there appears a kind of untrue closing phenomenon.
公路或铁路路基填筑完后，因前期施工过程中导线不通视及施工误差等多种原因，会出现直线与曲线不能闭合的情况。
Upon completion of subgrade filling for railways or highways, sometimes the straight line and curved line cannot close due to errors in construction or other reasons.
同时得出，闭合EDM无定向导线是一种很有潜力及值得推荐使用的导线。
Meanwhile the paper suggests that non-directional closed electronic distance measurement (EDM) traverse is potential and valuable in the network design and use.
否则，应从一已知点出发测至另一已知点以资校核，此时其闭合差应与导线边长成正比反符号进行分配。
Otherwise, it should be checked from one known point to another with proportional anti-symbol allocation between closing error and the length of side.
多边形的自动搜索是GIS空间分析的基本算法之一，同时也在地籍拆宗、导线网闭合环的闭合差计算等领域有着重要的作用。
Automatic searching polygon is one of essential algorithm in GIS spatial analysis and important used in cadastral treatment and closing error of traverse network calculation.
