| 摘 要： | 对用对角线法测量平面度误差时的测量点数据进行处理,求解直接用于平面度误差评定的数据-单点测量结果,根据《测量不确定度表示指南》（GUM）,对单点测量结果进行不确定度计算,总结得出单点测量结果及其不确定度分别为测量读数值及其不确定度的线性函数。

| Abstract: | Measurement dada of departures from flatness is processed when the measurement points are diagonal distribution. Single-point measurement result which is directly used to evaluate the departures from flatness is calculated. According to the "Guide to the Expression of Uncertainty in Measurement"(GUM), the uncertainty of Single point measurement result is also estimated. The formula deduced in this paper show that the result and its uncertainty are of single-point linear function of measurement reading data and its uncertainty. |
