| 摘 要： | 由于在直线度误差测量过程中的各种原因 ,导致许多观测数据与实际值偏离或者很难进行处理。文中介绍一种简单的处理原始实验数据的数学方法 ,即采用最小二乘理论对所测数据进行最优估计 ,来寻求最佳解。这种方法在实际生产和科学研究中具有一定价值

| Abstract: | Because of many reasons in the course of straightness error measuring, many original observed data deviate from actual value and are difficult to process. In order to seek optimal solution, a simple mathematical method to process observed data with the adoption of least square theory is described. |
