摘要
利用概率论 ,引入有关变量的数学期望值 ,导出了两种直线度误差评定方法的内在联系 ,从而提出一种建立在两端点连线法基础之上的直线度误差评定新思路。
Based the probability theory, the expectation values of relevant variables are introduced, the internal relations between two evaluation methods about straightness error are derived and a new evaluation method based on the line of two end-points is presented.
