一、前言自准式測角比較仪是根据比較測量的原理而設計制造的。从分析結果来看,該仪器結构比較簡单,也較稳定,在用来检定角度块时,足以达到規程中所要求的精度。本文主要提出了骸仪器各部件的检定方法并分析其对测量精度的影响,同时还分析了在使用这一仪器来检定角度块时由于角度块制造上的缺陷而給測量結果所带来的影响,从而得出 First, the foreword The self-contained goniometer comparator is based on the principle of comparative measurement and design. From the analysis of results, the instrument structure is relatively simple, but also more stable, when used to test the angle block, enough to meet the requirements of the accuracy of procedures. In this paper, we mainly present the verification methods of various parts of the skeletal instruments and analyze their influence on the measurement accuracy. We also analyze the influence on the measurement results caused by the defects in the angle block when using this instrument to test the angle blocks , To draw
