摘　　要：大半径小圆弧因可测量的圆弧段太短,会把测量误差放大,从而影响评价结果,引起单一的圆心和半径难以确定。本文讨论了如何在逻辑上避免此问题,并且提出一种新的描述及评价测量的方法。Smooth radius small circular arc due to the measurable period is too short, will reduce the measurement error enlarge, which affects the evaluation results, the single circle and the radius is difficult to determine. This article discussed how to avoid the problem on the logic, and proposes a new description and evaluation measurement method.

关 键 词：劣弧 小圆弧 描述 评价
