地表水和底泥中^(90)Sr的含量及相关性分析

Content and correlation analysis of ^(90)Sr in environmental surface water and sediment

为研究放射性核素的迁移规律,本文对中国不同地区共计62组地表水和配对底泥中^(90)Sr的含量数据进行了统计分析。结果表明,两种介质中^(90)Sr的含量呈现一定的线性关系,但整体上相关性不是很强,且未发现区域性规律。文中进一步讨论了影响两者相关性的原因,并对后续研究工作提出建议。

In order to study the transport process of ^(90)Sr,a statistical analysis of the content data in 62 groups of surface water and associated sediment in different regions of China has been conducted in this paper.The results showed that the content data of ^(90)Sr in two sample medias showed a certain linear relationship,but the overall correlation was not very strong,and no regional correlation was found.Further discussion on the factors affecting correlation was made and suggestions for the follow-up research works was put forward in this paper.
