A wide variety of single-celled organisms that live anaerobically , or without oxygen, had been found in the past, usually deep underwater or deep underground.

过去，科学家们已经发现了多种能在无氧环境中生存的单细胞生物，它们通常生活在深海区域和地表深处。

ANTICOR is the system which generates Cu-Fe ion or Cu-Al compound to protect internal surface of sea-water cooling pips from adhesion and growth of marine organisms by Cu-ion and protect copper alloys in condenser by forming Fe-ion or Al3 protective films as well.

ANTICOR 系统用来向海水中输送铜－铁离子或铜－铝离子。铜离子用来抑制海生物的生长并杀死海生物。铁/铝离子形成絮状物粘在冷却片及管壁上，使冷却片及管内壁免受腐蚀。

Researchers at the University of California in Los Angeles managed to do this using neurons from the sea slug Aplysia California, which is a good model for brain cells in other organisms, including humans.

More and more attention is focusing on the safty of drinking water suply. In this paper, firstly, chloramine formation and the characteristics and kinetics of monochloramine autodecomposition were studied. Secondly, considering the high concentration of ammonia and the complication of organic matters in Shanghai Huangpu River, formation characteristics and rules of disinfection byproducts were reviewed during the breakpoint chlorination process, and on the basis of grading and clssification of organisms, the control effects of chloramination on DBPs formation were studied. Finally, the formation rules of 2-monochlorophenol, 2,4-dichlorophenol and 2,4,6-trichlorophenol from phenol chlorination were investigated, and related influencing factors and kinetics were analysed.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
