| 摘 要： | 雪冰是重建过去时段甚至几十万年尺度气候环境状况的重要载体，其环境记录成为反演气候环境变化的重要依据。雪冰化学分析是实现这一目标的重要手段，其中雪冰样品的采集、运输及冰芯样品的提取和分割等过程是研究冰雪环境记录的关键环节。鉴于此，就上述过程的注意事项做了详细的阐述，并针对目前常规冰融系统中存在ICP-SMS样品颗粒溶解不完全、微量元素不精确等问题，引入了连续融解离散采样（CMDS）方法。

| Abstract: | Snow and ice can be served as an important indicator to retrieve the past climate and environment conditions,which even covers hundreds of thousands of years.Its environmental record has become an important basis for studying climate and climate change.The chemical analysis of snow and ice samples is an important means to achieve this goal.Snow and ice chemical analysis,including snow and ice samples collection,transportation,ice core sample extraction and segmentation processes,are the key links.In this paper,the above key links are pointed out.In addition,due to a big issue of the current conventional ice-melting system (ICP-SMS),a new method continuous melting of discrete samples (CMDS) is presented,which can be used to analyze the incomplete particle dissolution and trace elements accurately. |
