- Abstract:
- It is necessary for precise measurement to estimate the uncertainty of measurement result. When measuring flatness error in close way by pitch, usually the uncertainty of measurement result is independently estimated according to pitch points. By analyzing a concrete example, this paper proposed that the uncertainty should be evaluated by the correlation calculating method. This approach greatly improved the deficiencies of the assessment method according to independent measurement and enhanced measurement precision. It provides a reference value for uncertainty assessment in leveling a flat.
- 在精密测量中要求对测量结果的不确定度进行评估.本文通过实例分析, 指出用封闭法测平面度误差时, 测量结果不确定度应该按相关计算法求得.这一方法大大改善了按独立测量计算不确定度存在的问题, 提高了测量精度.该法对平板检定具有一定的参考价值.
