| 中文摘要: |
| 火试金法作为贵金属珠宝领域检测金含量的仲裁方法，方法涉及许多人为操作步骤，不同的操作过程可能对实验结果都会有不同的影响。通过对轧片过程中轧片方向的两种选择和三种不同金卷的厚度进行试验研究，计算标准金平行样品的极差值、平行样品的金含量和金卷的ICP差减法测得金含量三种结果对比，表明轧片方向和厚度对火试金测定结果并无影响。 |
| 英文摘要: |
| As an arbitration method for detecting gold content in precious metal jewelry field, fire assay involves many artificial operation steps. Different operation processes may have different effects on the experimental results. Through two choices of rolling direction and three different coils' thickness in the process of rolling, the comparison of the extreme difference of standard gold parallel sample, the gold content of parallel sample and the gold content of coil measured by ICP-AES subtraction method showed that the direction and thickness of rolling sheet had no influence on the results of fire assay. |
