最近我厂试制成功一种新的有色金属抛光膏。这种抛光膏具有良好的磨削作用,抛光速度也快,而且被抛光物件的表面光洁度很高(最高达▽▽▽▽_13级强,一般均在▽▽▽▽_(11、12)级)。当我们看到以后,就想起是否可以把它应用在有色金属金相试样的制备上。毛主席教导我们:“……你要有知识,你就得参加

Recently I successfully trial a new type of non-ferrous metal polishing paste. This polishing paste has a good grinding effect, polishing speed is fast, and the surface finish of the polished object is very high (up to ▽ ▽ ▽ ▽ _13 level strong, are generally ▽ ▽ ▽ ▽ _ (11, 12) level ). When we saw it, we remembered whether it could be applied to the preparation of non-ferrous metallographic samples. Chairman Mao taught us: ”... you have to have knowledge, you have to attend
