资料[1]介绍了计算平板平面度的简化公式,应用它来计算平面度确实提高了工作效率。借助(1)的思路,本文利用另外形式的简化公式,建立一个简化的计算表格。该表格就其计算工作量而言和(1)的方法相差无几,而在实用中却有如下的优点:计算步骤简单,明瞭;运算数目排列整齐,容易校对;计算结果一目了然。因此,简化表格不仅容易掌握而且进一步提高了工作效率。图1为过平板某条基线的截面图形。基线端点为 O、n。它们对于平板的理想平面 A_0的偏差是δh_0、δh_n(此二数值的确定可参考[1])。在 On
The data [1] introduced a simplified formula for calculating the flatness of the slab, which was used to calculate the flatness, which indeed improved work efficiency. With the idea of (1), this paper uses a simplified form of another form to create a simplified form. The table is similar to (1) in terms of its computational workload, but has the following advantages in practice: The calculation steps are simple and clear; The numbers are arranged neatly and easily, and the calculation results are clear at a glance. Therefore, simplifying the form is not only easy to grasp but also further improves work efficiency. Figure 1 is a cross-section of a baseline cross-section graphics. Baseline endpoints are O, n. Their deviations from the ideal plane A_0 of the slab are δh_0 and δh_n (see [1] for the determination of these two values). On
