三、表面光度块的构造和制造 使用标准表面光度块是在车间进行检查产品表面 光度的最主要的方法。因此,如何合理决定表面光度块 的构造,如何决定每套表面光度块的块数,为加强检查 表面光度的非常重要的工作。在一般机械制进厂内,表 面光度块的制造可采用以下方法: (1)表面光度 Third, the construction and manufacture of surface photometric block The use of standard surface photometric block in the workshop to check the product surface brightness of the most important method. Therefore, how to determine the structure of the surface photometric block rationally and how to determine the number of blocks of each surface photometric block are very important tasks for enhancing the surface luminosity inspection. In the general machinery into the plant, the manufacture of surface photometric block can use the following methods: (1) the surface luminosity
