Mariculture has.rapidly grow. w.rldw.de, w.ich might greatly influence the biogeochemical cycle of organic carbon in coas.al s.as. In this.s.udy, s.veral geochemical parameters. including grain s.ze compos.tion, s.dimentary total organic carbon (TOC), total nitrogen (TN), s.able carbon (δ13C) and nitrogen (δ15N) is.topic compos.tions. w.re analyzed for s.rface s.diments.collected from different mariculture zones.of s.nggou Bay and in different s.as.ns. w. inves.igated the compos.tion and dis.ribution of or- ganic matter in s.rface s.diments.and further evaluated the contribution of mariculture activities.to TOC s.urces. The TOC and TN contents.(mas. percentage) in the bay w.re in the range of 0.14% to 1.45% and 0.03% to 0.20%, res.ectively. The s.atial dis.ribution indicated that s.dimentary TOC and TN contents.in s.ellfis. monoculture and s.ellfis.-kelp polyculture zones.w.re higher than in other mariculture zones. w.ich might be related to grain s.ze compos.tion and mariculture organis.s. s.as.nal variations.of TOC contents.w.re obs.rved in different mariculture zones. The TOC/TN atomic ratio (C/N),δ13C and δ15N w.re in the ranges.of 5.97 to 10.97, 21.76‰ to 13.14‰ and 2.13‰ to 8.08‰, res.ectively, implying that s.dimentary organic matter in s.nggou Bay w.s.the mixture of marine phytoplankton, terres.rial and maricultural s.urces. A s.mple mixing model bas.d on δ13C w.s.applied and the res.lts.indicated that the relative contributions.of organic carbon s.urces.in s.nggou Bay follow.d the order kelp (36.6%) marine phytoplankton (28.7%) s.ellfis. bio-depos.tion (23.8%) terres.rial input (10.9%). s.rface s.diments.in s.nggou Bay w.re domi- nated by mariculture-derived organic carbon, w.ich on average accounted for 60.4% of TOC.

Buckling res.rained braces.（BRBs. have been w.dely applied in s.is.ic mitigation s.nce they w.re introduced in the 1970s.

In this.s.udy, a new.device called the multi-curve buckling res.rained brace （MC-BRB） is.propos.d to overcome thes. dis.dvantages. The new.device cons.s.s.of a core plate w.th multiple neck portions.as.embled to form multiple energy dis.ipation s.gments. and the enlarged s.gment, lateral s.pport elements.and cons.raining elements.to prevent the BRB from buckling. The enlarged s.gment located in the middle of the core plate can be w.lded to the lateral s.pport and cons.raining elements.to increas. buckling res.s.ance and to prevent them from s.iding during earthquakes.

Photolumines.ence of Zns.Clus.ers.in Zeolite-Y

引用

Journal of Materials.s.ience & Technology 1997年第5期13卷 397-404页

作者： Chen, w.w.ng, ZG lin, ZJ Xu, Y lin, LY Lab. of s.miconductor Materials.s.iences Institute of Semiconductors Chinese Academy of Sciences Beijing 100083 China

Tw. obvious.emis.ions.are obs.rved from the Zns.clus.ers.encaps.lated in zeolite-Y. The emis.ion around 355 nm is.s.arp and w.ak, locating at the ons.t of the abs.rption edge. The band around 535 nm is.broad, s.rong and s.okes.s.ifted. Both the tw. emis.ions.s.ift to blue and their intens.ties.firs.ly increas. then decreas. as.the loading of Zns.in zeolite-Y or clus.ers.s.ze decreas.s. Through inves.igation, the former is.attributed to the excitonic fluores.ence, and the latter to the trapped lumines.ence from s.rface s.ates. The clus.er s.ze-dependence of the lumines.ence may be explained qualitatively by cons.dering both the carrier recombination and the nonradiative recombination rates. Four peaks.appearing in the excitation s.ectra are as.igned to the trans.tions.of 1s.1s. 1s.1P, 1s.1D and s.rface s.ate, res.ectively. The excitation s.ectra of the clus.ers.do not coincide w.th their abs.rption s.ectra. The s.ates.s.litted by quantum-s.ze confinement are detected in the excitation s.ectra, but could not be differentiated in the optical abs.rption s.ectra due to inhomogeneous.broadening. The s.ze-dependence of the excitation s.ectra is.s.milar to that of the abs.rption s.ectra. Both the excitation s.ectra of excitonic and of trapped emis.ions.are s.milar, but change in relative intens.ty and s.ift in pos.tion are obs.rved.

Then through the analys.s.of local flow.field in the immediate neighborhood of rear s.rface, bas.d on the theory of vortex-induced vortex, a new.phys.cal mechanis. is.identified. At firs., the vertical vorticity on rear s.rface is.generated by the intrins.c three-dimens.onal ins.ability w.th the s.me ins.ability w.velength of mode A. Then the s.reamw.s. vorticity at a s.ecific s.gn is.induced by s.ch vertical vorticity, convected and concentrated in the s.ear layers. Finally, s.reamw.s. vortices.are formed and s.ed w.th alternatively s.edding s.anw.s. vortices.in the near w.ke. Moreover, the effect of induced s.anw.s. vorticity on original tw.-dimens.onal (2-D) s.anw.s. vorticity is.als. pres.nted in detail.
