摘要
本文简介金的内眼鉴别特征,提出排液失重法测定首筛成色时,浮力、可压缩性、表面浮力等诸因素影响的减免技巧,拟订了以基准金标定的准确、快速、无损的金成色测定法。
This paper briefly introduces how to distingwishgold by the naked eye, puts forword a method to reduce or even remove the influence brought about by the factors such as buoyance, compressibility and surface tension when a liquid draining weight less method is used in the determination of the relative purity of gold, and works out an accurate, rapid and no gold lossing determination method with criterion gold standardized.
