1气候变化和紫外线辐射对北极淡水鱼类及溯河产卵鱼类渔业的影响显示文摘北极淡水鱼类和洄游鱼类渔业为北方经济做出了重大贡献。但是,对于淡水水体,气候变化和增长的紫外线辐射对渔业产生的巨大影响有3个方面:可获鱼的数量、质量和捕捞成功率。因此,在这些影响发生作用之际,可能需要实质有效的适应行为以引导北极未来的渔业走向可持续性。当务之急是为商业渔业选择灵活和快速反应的'适宜管理'方式;改变生计渔业的当地土地和资源利用模式;改变很多休闲渔业的特性、管理方式和地点。总的来说,在气候变化及其对北极淡水水域和生物区影响的复杂性和不确定性情况下,为保证生态系统和主导鱼种有足够的恢复力和应对将来变化的能力,需要对渔业的各个方面实施更保守的管理办法。James D.Reist Frederick J.Wrona Terry D.Prowse J.Brian Dempson Michael Power Günter Kck Theresa J.Carmichael Chantelle D.Sawatzky Hannu Lehtonen Ross F.Tallman 曾首英 2006AMBIO-人类环境杂志2006,35,7:4
2用于电力系统仿真的潮流控制器模型显示文摘本文描述了—族基于可关断晶闸管(GTO)电压源逆变器的电力系统控制装置,介绍了静补(STATCON)、串联潮流控制器(SPFC)和统一潮流控制器(UPC)的稳态模型。静补是由美国的EPRI、TVA和西屋科技中心联合开发的基于逆变器的并联装置、不久它将被安装在TVA的16lkV输电系统上用于控制线路电压。而串联潮流控制器和统一潮流控制器则代表了静补在串联应用方面的拓展。这些装置的建模可以结合到现有的大型电力系统分析程序之中供系统稳态研究使用。IEEE的30母线试验系统的仿真结果证明了这些电压源潮流控制装置的稳态性能。UPFC具有能同时对线路的有功与无功潮流独立地进行控制的能力,可以认为它特别适用厂输电潮流控制。J.
