　　Rice is an important source of selenium(Se)exposure; however,the transformation and translocation of Se in the soil-rice system remain poorly understood.Here,we investigated the speciation of Se in Se-rich soils from Enshi,Central China and assessed which Se species is bioavailable for rice grown in Enshi.Extremely high Se concentrations(0.85 to 11.46 mg/kg)were observed in the soils.

基于三维光学扫描的大型壁板精准校形技术研究

本文针对当前运载火箭网格加筋壁板校形工艺难以满足精度要求的难题，提出一种基于三维光学扫描的精准校形技术.该技术针对三维光学扫描获得的真实变形壁板的形貌偏差点云数据开展了数据分析，分解出了产品的缺陷模式及相应大小.分析结果表明滚弯成型的曲面壁板经历机铣后主要的变形模式为曲率偏差，在较大筋高壁厚比下，壁板的曲率变化达12.7％.

太湖野生鱼血浆中药物和个人护理品的检测及鱼血模型的应用

药品及个人护理品(PPCPs)是一类新兴的污染物，广泛存在于水环境中，检出浓度在ng/L～μg/L水平[1]。长期暴露于低浓度的PPCPs中可能对鱼类和其他水生生物造成潜在的毒性，对水生生态系统造成危害[2]。野生鱼类是典型的脊柱水生生物，其血浆PPCPs浓度的分析具有重要的意义。
