With.ever increasing water demands and th. continuous intensification of water scarcity arising from Ch.na＇s industrial.z.tion, th. country is struggl.ng to h.rmoniz. its industrial.devel.pment and water suppl.. Th.s paper presents a systems anal.sis of water with. drawal. by Ch.nese industry and investigates demand- driven industrial.water uses embodied in final.demand and interregional.trade based on a mul.i-regional.input-output model. In 2007, th. El.ctric Power, Steam, and h.t Water Production and Suppl. sector ranks first in direct industrial.water with.rawal.（DWW）, and Construction h.s th. l.rgest embodied industrial.water use （EWU）. Investment, consumption, and exports contribute to 34.6%, 33.3%, and 30.6% of th. national.total.EWU, respectivel.. Specifical.y, 58.0%, 51.1%, 48.6%, 43.3%, and 37.5% of th. regional.EWUs respectivel. in Guangdong, Sh.ngh.i, z.ejiang, Jiangsu, and Fujian are attributed to international.exports. Th. total.interregional.import/export of embodied water is equival.nt to about 40% of th. national.total.DWW, of wh.ch.55.5% is associated with.th. DWWs of El.ctric Power, Steam, and h.t Water Production and Suppl.. Jiangsu is th. biggest interregional.exporter and deficit receiver of embodied water, in contrast to Guangdong as th. biggest interregional.importer and surpl.s receiver. With.ut impl.menting effective water- saving measures and adjusting industrial.structures, th. regional.imbal.nce between water avail.bil.ty and water demand tends to intensify considering th. water impact of domestic trade of industrial.products. Steps taken to improve water use efficiency in production, and to enh.nce embodied water saving in consumption are both.of great significance for supporting Ch.na＇s water pol.cies.

Water sol.bil.ty enh.ncements of pyrene by singl. and mixed surfactant sol.tions

引用

Journal.of Environmental.Sciences 2001年第4期13卷 491-496页

作者： z.u, l.-z. Ch.ou, C.T. Department of Environmental.Science Zhejiang University Hangzhou 310028 China

Water sol.bil.ty enh.ncements of pyrene by both.singl.-surfactant and mixed-surfactant sol.tions were compared and eval.ated. Th. sol.bil.ty of pyrene in water was greatl. enh.nced by each.of Triton X-100 (TX100), Triton X-405 (TX405), Brij 35 and SDS, in wh.ch.th. water sol.bil.ty enh.ncements increased with.increasing surfactant concentrations. Th. extent of sol.bil.ty enh.ncements at surfactant concentrations bel.w. th. CMC is th. order of TX100 > Brij 35 > TX405 > SDS; th. sequence at surfactant concentrations above th. CMC is TX100 > Brij 35 > SDS > TX405. Pyrene was sol.bil.z.d synergistical.y by anionic-nonionic mixed surfactant sol.tions, especial.y at l.w surfactant concentrations. Th. synergistic power of th. mixed surfactants is SDS-TX405 > SDS-Brij 35 > SDS-TX100. Th. synergism as noted is attributed to increasing Kmc and/or decreasing th. CMC of th. mixed surfactant sol.tion. For SDS-TX405 and SDS-Brij 35 mixed surfactant sol.tions, an increase in Kmc is coupl.d with.a decrease in th. CMC; for SDS-TX100, onl. a decreased in th. CMC val.e is noted. Mixed-surfactant sol.tions may improve th. performance of th. surfactant-enh.nced remediation (SER) of soil. by increasing th. bioavail.bil.ty and biodegradation of non-aqueous-ph.se organic pol.utants and reducing th. l.vel.of surfactant pol.ution and remediation expenses.

Numerical.Model.ng and Anal.sis of Grooved Surface Appl.ed to Fil. Cool.ng

Journal.of Bionic Engineering 2011年第4期8卷 464-473页

作者： l. Guo z. C. l.u Y. Y. Yan z. W. h.n Facul.y of Engineering University of Nottingham Nottingham NG7 2RD UK Department of Internal.Combustion Engine Jilin University Changchun 130022 P. R. China Key l.boratory of Bionic Engineering （Ministry of Education China） Jilin University Changchun 130022 P. R. China

In order to improve th. efficiency of fil. cool.ng, numerical.investigation was carried out to study th. effects of different fil.-cool.d pl.tes on surface h.at transfer. Both.grooved and non-grooved surfaces were concerned. Th. model.ng was per- formed using Fl.ent software with.th. adoption of Sh.ar-Stress Transport （SST） k-ωmodel.as th. turbul.nce cl.sure. Th. cool.nt was suppl.ed by a singl. fil. cool.ng h.l. with.an incl.nation angl. of 30°. Th. Mach.numbers for th. cool.nt fl.w and th. mainstream fl.w were fixed at 0 and 0.6, respectivel.. At th.ee bl.wing ratios of 0.5, 1.0 and 1.5, th. aerodynamic beh.viour of th. mixing process as wel. as th. h.at transfer performance of th. fil. cool.ng were presented. Th. numerical.resul.s were val.dated using experimental.data extracted from a bench.ark test. Good agreements between numerical.resul.s and th. ex- perimental.data were observed. For th. fil. cool.ng efficiency, it sh.ws th.t both.l.cal.and l.teral.y averaged cool.ng effectiveness can be improved by th. non-smooth.surface at different bl.wing ratios. Using th. grooved surface, th. turbul.nce intensity upon th. pl.te can be reduced notabl., and th. mixing between th. two fl.ws is weakened due to th. reduced turbu l.nce l.vel. Th. resul.s indicate th.t th. cool.ng effectiveness of fil. cool.ng can be enh.nced by appl.ing th. grooved surface.

作者： F.h. Cao l. Guo l.J. z.ang z. z.ang J. Q. z.ang Department of Ch.mistry Yuquan Campus Zhejiang University Hangzhou 310027 China State Key l.boratory for Corrosion and Protection of Metal. Institute of Metal Research The Chinese Academy of Sciences Shenyang 110016 China

Th. corrosion beh.vior of two different aged l.12 al.oys in EXCO （234g/l.NaCl. 50g/l.KNO3 0.1M h.O3） and MIl.h.600 （35g/l.NaCl. 5g/l.（Nh.）2SO4） sol.tions were studied using el.ctroch.mical.impedance spectroscopy （EIS） in conjunction with.SEM tech.ique respectivel., and th. ph.variation of th. above accel.rated corrosion sol.tion during material. corroding was al.o measured to ch.racteriz. th. corrosion processes. At th. beginning of corrosion, EIS pl.ts exh.bited two capacitive arcs in th. h.gh.frequency range （Cd） and mediate frequency range （ Cf） originating from th. original.corroded surface and th. newl. formed interface respectivel., and a l.w frequency inductive l.op due to th. rel.xation ph.nomenon of reaction intermediates. In th. EXCO,sol.tion, th. EIS resul.s sh.wed th.t once th. exfol.ation corrosion occurred, th. inductive l.op disappeared. Th. resul.s al.o sh.wed th.t th. exfol.ation corrosion susceptibil.ty of state T6 is much.h.gh.r th.n th.t of state T3, but th. intergranul.r corrosion susceptibil.ty h.s a reverse order. Based on th. rel.tionsh.p of EIS resul.s with.SEM and metal.oscopy morph.l.gies of th. corroding substrates and ph.sic-ch.mical.meaning of EIS parameters, an index （Cf/Cd） h.s been proposed to ch.racteriz. th. extent of th. l.cal.z.d corrosion, wh.ch.variation tal.ies with.th. real.corrosion extent correctl.. Meanwh.l., good agreement was found between th. experimental.resul.s and th. el.ctroch.mical.model.proposed and, good coh.rence between th. el.ctroch.mical.features and th. distribution type of constituent particl.s of corroding material.was observed.
