在检定工作中,经常会遇到视差现象,也经常要求对不足一格的值进行估读。因此,检定人员应把读取示值工作列为基本功之一,加以练习,以便做到准确、迅速。本文将简单地介绍一下在视差和估读中的一般问题。 In the verification work, often encounter the phenomenon of parallax, but also often requires less than one value to be evaluated. Therefore, the verification staff should read the value of work as one of the basic skills, to practice, so as to be accurate and rapid. This article will briefly introduce the general problems in parallax and estimation.
