摘要
针对教学和生产中遇到的实际问题,对理论正确尺寸的概念和应用进行了简要的分析和讨论,得出了理论正确尺寸是不附带公差的理想尺寸,用来确定被测要素的理想形状、理想方向和理想位置。
The text gives a brief analysis on theoretical exact size from two aspects:the concept and its application on setting the theoreti- cal condition,direction and location of the measured factors.It comes to a conclusion on solving the problems occurred during teaching and production.
