本文是日本的一个“长度测量精度专門委員会”所做的关于大尺寸长度测量现状的調查报告。该委員会搜集了大尺寸(500毫米以上)测量精度的文献资料,并对一些工厂的实际情况进行了调查和作了用同一量規的傅递測量比較試驗。报告对日本国内外大尺寸测量的现状、所使用的工具性能和结构特点等进行了綜合与分析报导。
This article is a survey by Japan’s “Special Committee on Length Measurement Accuracy” on the status of large-size length measurements. The committee collected literature on the measurement accuracy of large dimensions (over 500 mm), conducted surveys on the actual conditions in some factories and conducted comparative experiments on the Fu-mei using the same gauge. The report provides a synthesis and analysis report on the current status of large-size surveys at home and abroad, the tool performance and structural characteristics used.
