| 摘 要： | 密度法作为测定黄金饰品中金的含量的一种物理方法,具有无损、简单实用、准确、快捷、成本低等特点。密度法也叫流体静力学称量法即通过测定金饰品密度,计算金饰品的金含量。本工作测定了黄金饰品在不同温度、不同液体介质中的Au含量,结果表明,在室温下用蒸馏水或四氯化碳作测试的液体介质测试结果较好。

| Abstract: | Density method as a physical method can determine the gold content of ornament.It has the features of no loss,simple,practical,accurate and low cost.The density method is also called the fluid statics weight which can calculate the gold content of gold cornament by determining the density of gold cornament.In this work we determined the gold content of ornaments at different temperatures and in different liquids.The test results were better using distilled water or CCl_4 as medium at room temperature. |
