To investigate the affinity of the terrestrial microalgae to metal ions (Zn2+, Cu2+ and Ni2+) in aqueous solutions, four kinds of living algae (Oscillatoria, Botryococcus, Scenedesmus and Spirulina platensis Geitl, abbreviated as CZ, PTZ, SZ and LXZ) were chosen to biosorption experiment, and the mechanism of algae biosorption to metal ions were explored by fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Results show that four kinds of algae have a good affinity for Cu, Zn, the removal rate could reach more than 95%;while for Ni, compared with CZ, SZ and PTZ, the adsorption rate of LXZ is weak. The results of FTIR and SEM experiments revealed that the function groups such as carboxyl, hydroxyl, amino, sulfonic groups and so on are the main groups which played important role in the procedure of absorbing metal ions from water aqueous. Specific algae have different affinity to different metals which will be great helpful in the field of biosorption.

Automatic discovery and composition of Web services is an important research area in Web service technology, in which the specification of Web services is a key issue. This paper presents a Web service capability description framework based on the environment ontology. This framework depicts Web services capability in two aspects： the operable environment and the environment changes resulting from behaviors of the Web service. On the basis of the framework, a requirement-driven Web service composition model has been constructed. This paper brings forward the formalization of Web service interactions with π calculus. And an automatic mechanism converting conceptual capability description to the formal process expression has been built. This kind of formal specification assists in verifying whether the composite Web service model matches the requirement.

为探索南沙滨海泳场II期开发的可行性,对待建泳场周边人工湖、虎门—凫洲水道进行了原位围隔和围隔人工添加外源氮干预的对比试验研究,测定了各水体的8个理化指标和3个生物指标,并对为期6个月的监测数据进行了分析,同时根据地表水环境质量III类标准、按单因子评价法对水体作出水质评价。结果表明:人工湖水为IV类,总磷和化学需氧量(COD)未达标;湖围隔水除COD超标11%外,其他指标均达标;湖围隔加氮水总氮超标率为181%,COD超标率29.5%。水道水为劣V类,总氮浓度均值为2.48 mg?L–1,浮游植物生物量随时间变化呈增长趋势,并且以硅藻门藻属居多;水道围隔及围隔加氮水在7、9月以蓝藻为优势类群。与水道水相比,人工湖水更适宜用作泳场的供水源。
