摘要
度盘偏心对水平角的影响即与偏心距的大小有关也与偏心距的方向有关 ,当所测角的两边成一直线 ,且很短并与偏心距垂直时度盘偏心对测角影响最大 ,反之 ,当所测角的两边较长 ,其夹角很小时影响较小。但较大的度盘偏心必须校正 ,故介绍一种简单实用的检验、校正方法。
The effect of the optic theodolite board is relat ed with only the greatness of the deviation but also the direction of the deviation .It becomes the most wh en it is a vertical angle. On the contrast, It becomes the least when the two edges are lo ng and their angle is very little. But the considerable deviation must be adjusted. So thi s thesis introduces give a simple way to verity and adjust it.
