摘　　要：关于空间直线对基准平面的垂直度误差,有关规定只给出"最小区域"法评定准则,并没有给出相应算法。采取全局搜索包容小圆柱,逐次将包容柱的直径下降,使垂直度误差计算向"最小区域"逼近,从而获得高精度计算结果。In GB/T from 1958 to 2004, there is no calculation method on the perpendicularity error of straight line to the plane and the evaluation criterion. This paper develops a new method, searches for the small outer-contained cylinder, declines its diameter step by step and makes the calculation of the perpendicularity error approach to the smallest area to get high--precision calculation result.

关 键 词：垂直度误差 最小区域 高精度
