According to the a posteriori error estimator,a bubble placement method and constrained BLMG strategy are applied to solve elliptic problem with discontinuous coefficients which has strong singularity adaptively and efficiently,several numerical experiments are reported to support the efficiency of our adaptive method,including that the triangle remain well-shaped at any particular refinement levels,the grid size varies by several orders of magnitude.

汞的微生物甲基化作用是国内外汞生物地球化学循环领域的研究热点之一,然而,相关研究主要关注于水底沉积物中的厌氧菌,如δ-变形菌纲中的硫酸盐还原菌(Sulfate-Reducing Bacteria,SRB）和铁还原菌(Iron-Reducing Bacteria,IRB）等,而关于农业生态条件或森林生态系统中,具好氧性汞甲基化能力的微生物则鲜见报道.

研究背景氯化石蜡(CPs）是一类直链正构烷烃氯化衍生而成的复杂混合物[1].由于此类化合物在色谱上不能进行有效分离,质谱上产生一系列质量数相近的碎片离子,因此氯化石蜡的准确分析定量一直以来是一个难点.因此亟需进一步优化氯化石蜡的仪器分析方法对其进行更加准确的分析从而为其环境行为和对人体健康影响有更加准确的认识.该研究建立了负化学电离高分辨质谱高分辨质谱测定氯化石蜡的方法并应用于不同环境介质中氯化石
以云南洱海罗时江入湖河口湿地为典型对象,利用柱状底泥分层采样器采集罗时江河口湿地沉积物样品,0-10 cm为表层,10-30 cm为中层,30-60 cm为底层,分析了三层沉积物的总磷含量.研究结果表明:(1）从水平方向看,罗时江河口湿地各层(表层、中层、底层)沉积物总磷分布均呈现出沿两条主水道(水道Ⅰ和水道Ⅱ）向岸边递减,并在入水口处出现峰值的规律;垂直方向上看,总磷含量随着沉积深度增加而减少,

稀土、化肥、电镀和印刷等行业的产品生产过程中会产生大量的氯化铵废水,这类废水直接排放会对环境和人体造成巨大危害[1].目前,用于氯化铵废水处理主要有生物法、物化法、折点氯化法、磷酸铵镁沉淀法和电渗析等,但这些方法还存在处理成本高、难以达标、有副产物或高浓废液产生,可造成二次污染.双极膜电渗析(Bipolar membrane electrodialysis,BMED）是一项新的电渗析技术,其原理是
有机磷酸酯(organophosphate esters,OPEs）阻燃剂由于阻燃效果好、生产成本低等优点使用量逐年增加[1].目前,已有研究表明OPEs广泛存在于水体、沉积物、室内空气和灰尘等各种环境介质中,以及鱼类和人体血液等生物介质中[2],并且存在于环境中的OPEs会对人体健康产生负面影响.鉴于有机磷酸酯在环境、生物体和人体中较高程度的降解代谢及普遍性,准确分析环境样品中有机磷酸酯代谢物对
