| 摘要: |
| 痕量元素及其同位素采集、预处理和分析在海洋研究中具有重要的作用,对于认识全球环境变迁具有重要的价值。但其浓度在这些过程中易受沾污。本文结合海水痕量元素CTD现场采集工作环境,工作拉力等特殊要求,先后跟缆绳设计、生产制造厂家进行缆绳相关技术讨论、确定缆绳各项技术指标。设计敷塑纤维通讯缆,并委托缆绳生产厂家加工出样缆两条。通过对样缆进行静态拉力试验验证缆绳自身工作拉力,并通过成分分析、浸出试验验证最大化减少缆绳对于海中溶解态痕量金属的沾污。该研究结果可提高采样过程的可靠性,保证数据的准确率。 |

| Abstract: |
| The collection, pretreatment, and analysis of trace elements and their isotopes play an important role in marine research and are highly valuable for understanding global environmental changes. However, trace element concentrations are susceptible to contamination in these processes. In this paper, bearing in mind the special requirements for the environment, working tension, and other special aspects of the seawater trace element conductivity, temperature, and pressure field collection work, we have successively discussed the related technology of the cable regarding its design with the cable manufacturer to determine its technical indicators. We designed a plastic fiber communication cable and commissioned the manufacturer to process two sample cables. The static tension test of the sample cable verified the working tension of the cable itself, and the verification of component analysis and leaching test minimized the cable's contamination of dissolved trace metals in the sea. The research results could improve the reliability of the sampling process and ensure data accuracy. |
