| 中文摘要: |
| 金在矿石中往往以自然金的状态存在，嵌布极不均匀，且富有延展性，给样品制备造成一定困难。在分析测试工作中发生质量不合格的原因，大多是由试样的均匀性和代表性太差造成的。实践证明，只有在样品制备过程中，严把样品接收关，严格控制样品损耗，合理确定样品制备流程，及时进行内检和弃样抽查，防止污染和顺序混乱，才能保证最终分析结果的准确可靠。 |
| 英文摘要: |
| The gold was existed in the status of natural gold in the ore. It brings some difficulties for sampling because of poor homogeneity and rich ductility of gold. The reason caused to the unqualified analytic result in the procedure was mainly the inhomogeneous and representative of samples. In order to get accurate and reliable analysis results, more attention should be paid to sample processing, such as receiving, control of sample loss rate, reasonable processing procedure, timely inner inspection, re-examination of abnormality, avoiding of pollution and disorder. |
