1空间平等与总体经济效率——中国区域经济格局转型分析显示文摘二战以来,多数发展中国家始终面对如何实现空间平等和总体经济效率兼容的严峻考验,其所具有的共同区域经济特征是:国民经济增长在空间上分解为两极:一极是少数地区持续的经济高涨;另一极是多数地区持续的经济落后、停滞。空间上的两极分化更主要更直接的表现是人口、社会经济活动在空间上的过渡集中以及地区之间收入水平差异的扩大。谷书堂 唐杰 M.Fujita 1994经济研究1994,29,8:20
2Comparison of Soil Fauna (Oribatids and Enchytraeids)Between Conventional and Organic (Tillage and No-Tillage Practices) Farming Crop Fields in Japan显示文摘The major soil animal groups, enchytraeid worms and oribatid mites, were compared in the abundance and diversity between conventional fields (CT) and organic farming fields with tillage (OT) or no-tillage (ON) practices. The values of abundance, species richness, diversity and evenness were significantly larger in OT and ON than in CT, indicating that the abundance and diversity in organic farming fields were greater than those in conventional farming. The community structure of enchytraeid genera was different between OT and ON. Enchytraeus was the most abundant in OT, while Fridericia in ON. The abundance of oribatids in OT was similar to that in ON, while the species richness and diversity in the former were smaller. These results suggested that no-tillage practice under organic management might contribute to the improvement in quality of soil mesofauna.M.FUJITA S.FUJIYAMA 2001Pedosphere2001,11,1:7
32011年日本东北近海地震震源上方的位移显示文摘2011年3月11日,一次大的板间地震(Mw9.0)发生在日本东北宫城县附近的板块交界处。根据余震分布推测的震源区为约500km长、200km宽的近海区(Japan Meteo-rological Agency,2011)。各种不同的研究正在围绕着理解该地震发生的震源机制展开。M.Sato T.Ishikawa N.Ujihara S.Yoshida M.Fujita M.Mochizuki A.Asada 万永革(译) 吕春来(校) 2011世界地震译丛2011,42,3:1
4采用氢氧化锂提高铝合金氧化膜的耐腐蚀性能显示文摘为了提高发动机和汽车车身铝合金部件的耐腐蚀性能,通常会在铝合金表面形成阳极氧化膜。由于这些氧化膜为多孔结构,因此必须对孔隙进行封闭处理,以进一步提高其耐腐蚀性。将氧化膜放在沸水或含封孔添加剂的溶液中进行处理后,其孔隙就会被水合氧化铝封闭。由于处理时间长,溶液温度高,这种水化封闭处理的能耗较高。为了解决上述问题,开发了一种采用氢氧化锂溶液的封闭处理(锂封闭处理)技术。锂封闭处理主要采用铝酸锂复盐对孔隙进行封闭,这种复盐能在室温下的强碱性溶液中快速生成,因此,封闭处理时间可缩短至传统方式的1/10。并且,这种复盐能从氧化膜的表面向深层发展,尤其能在氧化膜的表层生成更多复盐,有助于提高耐腐蚀性能。已将这种锂封闭处理技术应用于在严重腐蚀环境下使用的汽车外部机械零件。M.Fujita H.Tanaka H.Muramatsu H.Asoh S.Ono 程玉发 陈晓峰 2015国外内燃机2015,47,1:1

8Principles for managing marine ecosystems prone to tipping points显示文摘As climatic changes and human uses intensify,resource managers and other decision makers are taking actions to either avoid or respond to ecosystem tipping points,or dramatic shifts in structure and function that are often costly and hard to reverse.Evidence indicates that explicitly addressing tipping points leads to improved management outcomes.Drawing on theory and examples from marine systems,we distill a set of seven principles to guide effective management in ecosystems with tipping points,derived from the best available science.These principles are based on observations that tipping points(1)are possible everywhere,(2)are associated with intense and/or multifaceted human use,(3)may be preceded by changes in earlywarning indicators,(4)may redistribute benefits among stakeholders,(5)affect the relative costs of action and inaction,(6)suggest biologically informed management targets,and(7)often require an adaptive response to monitoring.We suggest that early action to preserve system resilience is likely more practical,affordable,and effective than late action to halt or reverse a tipping point.We articulate a conceptual approach to management focused on linking management targets to thresholds,tracking early-warning signals of ecosystem instability,and stepping up investment in monitoring and mitigation as the likelihood of dramatic ecosystem change increases.This approach can simplify and economize management by allowing decision makers to capitalize on the increasing value of precise information about threshold relationships when a system is closer to tipping or by ensuring that restoration effort is sufficient to tip a system into the desired regime.Kimberly A.Selkoe Thorsten Blenckner Margaret R.Caldwell Larry B.Crowder Ashley L.Erickson Timothy E.Essington James A.Estes Rod M.Fujita Benjamin S.Halpern Mary E.Hunsicker Carrie V.Kappel Ryan P.Kelly John N.Kittinger Phillip S.Levin John M.Lynham Megan E.Mach Rebecca G.Martone Lindley A.Mease Anne KSalomon Jameal F.Samhouri Courtney Scarborough Adrian C.Stier Crow White Joy Zedler 2015Ecosystem Health and Sustainability2015,1,5:0
