一、引言在机械装配技术中,圆柱试件内径的精确测量具有十分重要的意义。圆柱试件的内径通常用高灵敏度的比较仪来测量。用于比较的参考标准是研合在平晶上的量块。这种比较
I. INTRODUCTION In the mechanical assembly technology, the precise measurement of the inner diameter of the cylindrical specimen is of great significance. The inside diameter of a cylindrical specimen is usually measured with a highly sensitive comparator. The reference standard used for comparison is a gauge block that is ground on a flat crystal. This comparison
