关于量块检定两种比较法测量的讨论

Discussion about two comparative methods of gauge block calibration

长期以来,国内外对低等级量块进行检定通常采用的是比较法.本文主要讨论了中国传统的“点到面”式和西方国家通常使用的“点对点”式两种比较检定方法,介绍这两种检定方法的工作过程和检定结构,并对二者进行了比较,对以后关于量块检定方法的研究和完善,改进量块的检定结构具有一定借鉴作用.

For a long time, the comparative method is commonly used in calibrating the lower grade gauge blocks at home and abroad. This paper mainly discusses two kinds of calibrating methods-the traditional method of “point to surface” in our country and the method of “point to point” mainly used in west countries, and introduces the working processes and structures of the two methods, and then compares with them. So it will play a major role in researching the method of calibrating gauge blocks and improving the calibrating structure.
