摘要
介绍了两点法误差分离技术（Ｅｒｒｏｒ Ｓｅｐａｒａｔｉｏｎ Ｔｅｃｈｎｉｑｕｅ，即： ＥＳＴ）的原理，并在轧辊坯素线直线度误差测量中应用，对测量结果进行了分析，表明两点法误差分离技术应用于轧辊坯素线直线度误差测量，大大提高了测量精度和测量效率。
The principle of two - point method EST is introduced. It is applied in measuring the straightness error of the profile lines of roll billets. The Measuring result is analysed. The result shows that measuring precision and efficiency are elevated.
