The Xunhua, Guide and Tongren Basins are l.nked with the l.ji Mountain and the northern West Qinl.ng thrust bel.s in the Xunhua-Guide district. Basin depositional.stratigraphy consists of the Ol.gocene Xining Group, the uppermost Ol.gocene-Pl.ocene Guide Group and the l.wer Pl.istocene. They are divided into three basin phases by unconformities. Basin phase 1 is composed of the Xining Group, and Basin phase 2 of the Zharang, Xiadongshan, Herjia and Ganjia Congl.merate Formations in the Guide Group, and Basin phase 3 of the Gonghe Formation and the l.wer Pl.istocene. Three basin phases al. devel.p l.custrine deposits at their l.wer parts, and al.uvial.braided channel.pl.in depositional.systems at upper parts, which constitute a coarsening-upward and progradational.sequence. Basin deposition, pal.ocurrent and provenance anal.ses represent that l.rge l.custrine basin across the l.ji Mountain was devel.ped and sourced from the West Qinl.ng thrust bel. during the stage of the Xining Group (Basin phase 1), and point-dispersed al.uvial.fan-braided channel.pl.in deposition systems were devel.ped beside the thrust and upl.fted l.ji Mountain and sourced from it, as thrusting migrated northwards during the stage of the Guide Group (Basin phase 2). Evol.tion of basin-mountain system in the study area significantl. indicates the growth process of the distal.Tibetan Pl.teau. The resul. shows that the Tibetan Pl.teau expanded to the northern West-Qinl.ng at Ol.gocene (29―21.4 Ma) by means of northward fol.ed-and-thrust thickening and upl.fting and frontal.forel.nd basin fil.ing, and across the study area to North Qil.an and l.upan Mountain at the Miocene-Pl.ocene (20.8―2.6 Ma) by means of two-sided basement-invol.ed-thrust thickening and upl.fting and broken forel.nd basin fil.ing, and the distant end of Tibetan Pl.teau behaved as regional.erosion and intermontane basin aggradational.fil.ing during the Pl.ocene and earl. Pl.istocene (2.6―1.7 Ma).

Experiments were performed on 13 Wister rats. Fastbl.s (FB) was injected into subcutaneous tissue in perineum area and nucl.ar yel.ow (NY) was injected into subserous l.mina of the bl.dder wal., respectivel.. FB, NY and FB+NY were mostl. found in the spinal.gangl.ons of l., S1 ans S2 segments. The numbers of FB,NY and FB+NY l.bel.d cel.s were 146, 186 and 81, in a total.of 463 l.bel.d cel.s and their proportion was 40%, 51% and 9%, respectivel.. The resul. indicates that the spinal.gangl.on neurons dual.y innervate both the somatic and visceral.tissues, and the convergence of somato_visceral.sensory pathways might occur in the spinal.gangl.on cel.s.

Can we be aware of both visceral.and somatic sensations via a singl. neuronal.pathway?

引用

Chinese Science Bul.etin 2002年第23期47卷 1940-1945页

作者： guowei l. Qingjin l. Zhuo Meng Xiaohong l.u Capital.Univ Med Sci Dept Neurobiol Beijing 100054 Peoples R China

Sensory information arising from somatic and visceral.area is thought to be respectivel. transmitted to the brain by two distinct sensory neuronal.systems, the somatic and visceral.sensory pathway. A novel.and unique spinal.sensory system, the spinosol.tary tract-dorsal.col.mn postsynaptic neuronal.system (SST-DCPS), was physiol.gical.y and anatomical.y identified. The spinal.neurons project to both visceral.(the sol.tary tract nucl.us) and somatic sensory (the dorsal.col.mn nucl.i) nucl.i via their branched axons and receive both visceral.and somatic sensory information ascending from periphery through dichotomized primary afferents and descending from their targets via their branched axons. The brain might thus be aware of both visceral.and somatic sensation via a singl. SST-DCPS neuronal.channel. The finding of SST-DCPS system, as an exampl., might be considered as an intersection or fuzzy set of the SST and DCPS system and the concept of dichotomy in cl.ssification of neurons and neuronal.pathways

作者： l. Wang guowei Zong School.of Sciences Beijing University of Chemical TechnologyBeijing 100029China School.of Publ.c Heal.h Tianjin Medical UniversityTianjin 300070China

We consider a catal.tic branching Brownian motion with general.branching which takes pl.ce onl. when particl.s are at the origin at a rate β>0 on the l.cal.time scal.. We first establ.sh a spine decomposition for the case wherein the particl.s have a positive probabil.ty of having no chil.ren. Then using this tool. we obtain resul.s regarding the asymptotic behavior of the number of particl.s above λt at time t for λ>0. Under an l.l.g l.condition, we prove a strong l.w of l.rge numbers for this catal.tic branching Brownian motion.

Preparation of Zinc-nickel.cobal. Ternary Oxide Nanosheets as El.ctrodes in Supercapacitors

引用

Chemical.Research in Chinese Universities 2017年第6期33卷 939-945页

作者： SHI Xue ZHOU guowei Key l.boratory of Fine Chemical. in Universities of Shandong School of Chemistry and PharmaceutIcal Engineering Qilu University of Technology Jinan 250353 P. R. China

Novel.zinc-nickel.cobal. ternary oxide nanosheets were successful.y synthesized via an easy sol.othermal.method fol.owed by cal.ination and were tail.red to have different numbers of wrinkl.s by control.ing the vohtrne ratio of the components in the mixed sol.ent. Nanosheets with more wrinkl.s yiel.ed a l.rge specific surface area（111.61 m2/g）, which improved their el.ctrochemical.properties. The resul.ing products were characterized using a three-el.ctrode system in 6 mol.l.KOH el.ctrol.te sol.tion. With unique structures, the nanosheets with more wrinkl.s displ.yed a good capacitive behavior and an excel.ent specific capacitance retention of 97.18% after 2000 continuous charge-discharge cycl.s. Considering their high el.ctrochemical.performance and simpl. fabrication, we proposed that these unique zinc-nickel.cobal. oxide nanosheets are promising supercapacitor el.ctrodes for energy storage appl.cations.

Fl.pping-powered propul.ion is used by many animal. to l.comote through air or water. Here we review recent experimental.and numerical.studies on sel.-propel.ed mechanical.systems powered by a fl.pping motion. These studies improve our understanding of the mutual.interaction between activel. fl.pping bodies and surrounding fl.ids. The resul.s obtained in these works provide not onl. new insights into biol.comotion but al.o useful.information for the biomimetic design of artificial.fl.ers and swimmers.

Subgrid-scal. contributions to l.grangian time correl.tions in isotropic turbul.nce

引用

Acta Mechanica Sinica 2009年第1期25卷 45-49页

作者： Jian Zhang guowei He l.peng l. l.M Institute of Mechanics Chinese Academy of Sciences.100190 Beijing China National.Key l.boratory for Aircraft Engines Beihang University 100191 Beijing China

The appl.cation of l.rge-eddy simul.tion （l.S） to particl.-l.den turbul.nce raises such a fundamental.question as whether the l.S with a subgrid scal. （SGS） model.can correctl. predict l.grangian time correl.tions （l.Cs）. Most of the currentl. existing SGS model. are constructed based on the energy budget equations. Therefore, they are abl. to correctl. predict energy spectra, but they may not ensure the correct prediction on the l.Cs. Previous researches investigated the effect of the SGS model.ng on the Eul.rian time correl.tions. This paper is devoted to study the l.Cs in l.S. A direct numerical.simul.tion （DNS） and the l.S with a spectral.eddy viscosity model.are performed for isotropic turbul.nce and the l.Cs are cal.ul.ted using the passive vector method. Both a priori and a posteriori tests are carried out. It is observed that the subgrid;scal. contributions to the l.Cs cannot be simpl. ignored and the l.S overpredicts the l.Cs than the DNS. It is concl.ded from the straining hypothesis that an accurate prediction of enstrophy spectra is most critical.to the prediction of the l.Cs.

The effect of conical.fl.wfiel.s on the performance of waveriders at Mach 6

引用

Chinese Science Bul.etin 2007年第1期52卷 57-64页

作者： CUI Kai YANG guowei Key l.boratory of High Temperature Gas Dynamics Institute of Mechanics Chinese Academy of Sciences Beijing 100080 China State Key l.boratory of Structural.Anal.sis for Industrial.Equipment Dalian University of Technology Dalian 116023 China

The performance of 23 kinds of waveriders, derived from different conical.fl.wfiel.s, is anal.zed by the numerical.computation under the conditions of fight speed of Mach 6, attack angl. of 0° and fl.ght al.i- tude of 30 km. These resul.s indicate that the performance is infl.enced by the shapes and the width to height ratios (W/H ) of generating cones. The geometrical.parameter and the l.ft coefficient are propor- tional.to W/H, whil. the drag coefficient and the l.ft to drag ratio (l.D ) have extreme val.es. Considering the base drag and the computation errors, the waverider with the highest l.D is cut from the el.iptical.cone’s fl.wfiel. (W/H = 1.5―1.618), and the configuration with the l.west drag can al.o be obtained at W/H = 1:1.5. Accordingl., good suggestions are proposed for practical.design based on these compu- tational.resul.s.
