汞在大气-植被-土壤界面间的迁移转化一直是近年来研究的热点,稳定汞同位素添加技术为这一科学问题的研究提供了新的手段,而如何产生低浓度、稳定、连续且经济可行的单一汞同位素大气(~(xxx)Hg~0)是试验研究的难点与关键。本试验旨在设计、创建微环境单一汞同位素富集大气的发生系统,该系统不仅具有低成本,可以连续产生低浓度、稳定性强、可控性高、利用效率高的同位素汞蒸气(~(xxx)Hg~0)特性,还兼有轻便灵巧、安装便捷、可移动性强和适用范围广等特点。 |

In the atmosphere-vegetation-soil interface,the migration and transformation of mercury has been a hotspot research in recent years.The novel technology presented here for the investigation of a stable isotope of mercury provides a new means for the scientific research.The possible difficulties and the successful experimental key of the technology is the simulation of the atmospheric environment that there is sustained,stable and low concentrated of single mercury isotope.This experiment aims to design and create a system of atmospheric microenvironment which can add not only the single mercury isotopes,but also combine characteristics low concentration gradient,with strong stability,high controllability,high efficiency,smart and lightweight,easy installation,high mobility and wide application of the technology. |
