平面度误差评定中离散min-max问题研究与软件设计

在以最小二乘法或其他方法所获得的初始基准平面基础上，继续对该平面作有意识的微小扰动，把测量点集与基准平面距离之max值减小，逐步逼近真值，使平面度误差计算得到合理的解决，计算结果真正满足最小条件准则．

Min-max Research and Software Design in the Assessment of Flatness Error

Based on the datum plane obtained by the least squares method or other methods, tiny perturbation was performed to reduce the max value between measured point set and the datum plane and approach the real value gradually, which solve the typical discrete minmax problem of flatness error and make the results meet the minimum conditions criteria.
