一、前言我厂原有国产立式金相显微镜及生物显微镜所改装的金相显微镜,均无照相设备,只能做目测观察,不能进行金相照相。这样,对试验工作有着一定的局限性,满足不了生产上的要求。为了解决因设备条件不足所产生的困难,我们根据照相原理,创造了用金相显微镜直接照相的方法,在暗室内,将影像投射在投影屏上或墙上,在影屏上放着感光材料,直接拍下各种倍率的照片,见图1、2、3。

First, the foreword Our factory made the original vertical microscope and biological microscope modified microscope, no photographic equipment, can only do visual observation, can not be metallographic. In this way, the experimental work has certain limitations, can not meet the production requirements. In order to solve the difficulties caused by the lack of equipment conditions, we based on photographic principles, and created a direct use of metallographic microscope photography method, in the dark room, the image projected on the projection screen or wall, the screen is placed on the photosensitive material , Directly photographed a variety of magnification photos, see Figure 1,2,3.
