同轴度误差与对中误差的区别

从5个方面对同轴度误差与对中误差进行了比较，指出二者虽然都是关于两轴线相对位置关系的问题．具有较大的相似性，但是在本质上二者却是具有较大的差异的不同问题．明确了二者自身的内涵与特点，便于更准确地使用两个概念．有利于根据二者的特点来寻求进一步提高各自精度的方法，同时也指出了有待进一步深入研究的关于二者的课题．

Differences Between Coaxiality Error and Shaft Alignment Error

In this paper, the differences between shaft alignment error and coaxiality error are introduced from five aspects. The two errors are different essentially although they are very similar. And then nail down the meaning and the characters of the two errors, so as to use the two concepts more exactly, and be good to seek the methods that can improve the. accuracy of the two errors by themselves characters, at the same time, some problems about the two errors are presented.
