| 中文摘要: |
| 采用火花直读光谱法测定纯银中的20种杂质元素，用差减法计算出银含量。对制样方法，分析方法等进行了研究。实验结果稳定，可靠，重复性好，可用于测定银含量为99.9%~99.99%银产品。 |
| 英文摘要: |
| The 20 impurity elements of fine silver were determined by the spark direct reading spectrometric method. The content of silver was calculated by the subtraction method in the percentage of weight. The method of sample preparation and analysis method were studied. The experimental results are stable, reliable, reproducible and suitable for measuring silver content of 99.9%~99.99%. |
