在生产检验中,经常要测定材料或部件的某种组织或缺陷的实际尺寸,以及与标准图片对照比较。评定时则要求所使用的显微镜放大倍数准确。为此需要准确地测定显微镜倍数。我们在实际工作中,经多次试验总结出一个简便的测定方法。一、放大倍率的测定方法 1.金相显微镜放大倍率的测定,通常是利用物镜测微尺和安装在观察者眼睛明视距
In production testing, it is often necessary to determine the actual size of a structure or defect of a material or component, as well as to compare with a standard picture. Evaluation requires the use of microscope magnification accurate. To do this requires accurate determination of the microscope fold. In practical work, we conclude a simple and convenient method by many experiments. First, the determination of the magnification 1.
