资料[1]、[2]介绍了“三点连环求解法”在检定基准母尺及用短平尺测量长导轨弯曲度的应用。它具有方法简便、精度高、以及避免应用贵重精密的平面度检查仪器等优点。由于[1]所介绍的计算公式比较复杂,计算工作量甚大,故在应用该法时,通常是使用图解法。和计算法相比,图解法的计算误差较大。另外,作出一张准确的图形往往需要一些准备作图工具等的辅助时间,尤其在车间现场更是如此。何况“三点连环求解法”的作图比起采用水平仪测量平直度的作图复杂得多。因此,正如(1)所指出的:“如何找到简便而又准
The data [1], [2] introduced the application of “three-point sequential solution method” in the test of the reference master and the measurement of the curvature of the long guide rail with a dipstick. It has the advantages of simple method, high precision, and avoiding the application of expensive flatness inspection instruments. As [1] describes the calculation of the formula is more complex, computational workload is very large, so the application of the law, it is usually the use of graphic method. Compared with the calculation method, the calculation error of the graphic method is larger. In addition, making an accurate graphic often requires some assistance with preparation tools, especially at the shop floor. Moreover, the mapping of the “three-point serial solution method” is much more complicated than the mapping of the flatness with the level meter. Therefore, as (1) states: "How to find easy and accurate
