Study and Application of In-field Analytical Methods and Instruments for Determination of Trace Manganese in Seawater

摘要 锰（Mn）是生物生长的必需微量元素，在海洋浮游植物的光合作用和体内自由基清除等过程中起着重要作用。海水中的Mn可示踪多种生物地球化学过程，并参与其他典型生源要素的循环，进而影响海洋生态系统。大洋海水中，溶解态Mn的浓度非常之低。为了深入理解Mn在海洋生物地球化学过程中的作用，现有的测定海水中痕量Mn的方法仍需发展和突破。本论文研发了5种具有现场应用前景、灵敏度高、简便自动的海水中痕量Mn的分析方法和相应分析仪器，主要内容和结果如下： 1) 基于1-(2-吡啶基偶氮)-2-萘酚（PAN）与Mn的络合显色体系，建立了可用于海水中溶解态Mn分析的流动注射分光光度测定法。方法检出限为14nm...Abstract Manganese (Mn) is an essential micronutrient for marine phytoplankton growth and plays an important role in the processes of photosynthesis and free radicals elimination. Believed to serve as a useful chemical tracer in many biogeochemical processes, Mn is also involved in cycles of other biogenic elements, and could further influence the marine ecosystem. Dissolved Mn exists in the open...学位：理学博士院系专业：环境与生态学院_环境科学学号：3312012015355

A Study of Capital Allocation Efficiency in Economic Growth ——based on Central China

资本总量的积累和配置效率的提高都能促进经济增长。在资本规模既定的情况下，提高资本配置效率对于促进我国中部地区崛起，具有重要的现实意义。 首先，本文基于JeffreyWurgler的“资本配置效率”模型，用中部六省1999-2009年间36个工业行业数据进行回归分析，得到中部地区1999-2009年总体资本配置效率为0.4539，中部地区六个省份中，河南省总体资本配置效率最高。其次，在分年度回归中，本文发现中部整体的资本配置效率在2006年达到最高，之后逐年下降，但中部地区各省份资本配置效率随时间的变动却各不相同。本文还发现，中部各省资本配置效率的变动与各省的GDP增长率的变动呈现明显的正相关...Both capital accumulation and improving of capital allocation efficiency can promote economic growth. However, in the case of net capital outflow in a long time, it has important practical significance for central China to develop economic, and promote the Rise of Central China, from a point of view of improving capital allocation efficiency.
