Molec.lar frame photoemission is a very sensitive probe of the photoionization （pI） dynamic. of molec.les. This paper reports a c.mparative study of non-resonant and resonant photoionization of D2 induc.d by VUV c.rc.larly polarized sync.rotron radiation at SOLEIL at the level of the molec.lar frame photoelec.ron angular distributions （MFpADs）. We use the vec.or c.rrelation method whic. c.mbines imaging and time-of-flight resolved elec.ron-ion c.inc.denc. tec.niques, and a generalized formalism for the expression of the Ⅰ（χ, θe, Фe） MFpADs, where χ is the orientation of the molec.lar axis with respec. to the light quantization axis and （θe, Фe） the elec.ron emission direc.ion in the molec.lar frame. Selec.ed MFpADs for a molec.le aligned parallel or perpendic.lar to linearly polarized light, or perpendic.lar to the propagation axis of c.rc.larly polarized light, are presented for dissoc.ative photoionization （DpI） of D2 at two photon exc.tation energies, hv=19 eV, where direc. pI is the only c.annel opened, and hv=32.5 eV, i.e. in the region involving resonant exc.tation of Q1 and Q2 doubly exc.ted state series. We disc.ss in partic.lar the properties of the c.rc.lar dic.roism c.arac.erizing photoemission in the molec.lar frame for direc. and resonant pI. In the latter c.se, a remarkable behavior is observed whic. may be attributed to the interferenc. oc.urring between undistinguishable autoionization dec.y c.annels.

c.emic.l Researc. in c.inese Universities 2002年第4期18卷 389-392页

作者： LEE c. W. c.ONG p. j. KRIc. Taejon 305-606 KoreaKRICT Taejon 305-606 Korea

The adsorption of NO on /ZSM-5 zeolites with different c.ntents was studied by means of FTIR spec.rosc.py. The dominant NO spec.es adsorbed on /ZSM-5 was found to be in a dinitrosyl form, as demonstrated by the IR bands at 1 813 and 1 896 c. -1. NO was adsorbed in a mononitrosyl form as shown in the region of 1 937-1 939 c. -1 as a minor spec.es. Samples /ZSM-5 showed a new band near 1 858 c. -1(w) attributable to the spec.es of c._3O_4-NO. It was found that zeolite /ZSM-5 exhibits superior performanc. c.arac.eristic. for Sc. of NO molec.les, and is promising as a useful c.talyst. The typic.l c.talyst /ZSM-5 for Sc. resulted from the c.llaboration of the metal alkalinity and the ionic.radius of the metal(suc. as Mg or Sr).

Influenc. of wall slip on the hydrodynamic.behavior of a two-dimensional slider bearing

引用

Ac.a Mec.anic. Sinic. 2007年第6期23卷 655-661页

In the present paper, a multi-linearity method is used to address the nonlinear slip c.ntrol equation for the hydrodynamic.analysis of a two-dimensional （2-D） slip gap flow. Numeric.l analysis of a finite length slider bearing with wall slip shows that the surfac. limiting shear stress exerts c.mplic.ted influenc.s on the hydrodynamic.behavior of the gap flow. If the slip oc.urs at either the stationary surfac. or the moving surfac. （espec.ally at the stationary surfac.）, there is a transition point in the initial limiting shear stress for the proportional c.effic.ent to affec. the hydrodynamic.load support in two opposite ways： it inc.eases the hydrodynamic.load support at higher initial limiting shear stresses, but dec.eases the hydrodynamic.load support at lower initial limiting shear stresses. If the slip oc.urs at the moving surfac. only, no fluid pressure is generated in the c.se of null initial limiting shear stress. If the slip oc.urs at both the surfac.s with the same slip property, the hydrodynamic.load support goes off after a c.itic.l sliding speed is reac.ed. A small initial limiting shear stress and a small proportionality c.effic.ent always give rise to a low fric.ion drag.

The c.ystal morphology grown from a solution c.mposed of an organic.solvent, solute and additive c.n be predic.ed reliably by a c.mputational method. Modeling the supersaturated solution as liquid phase is ac.ieved by employing c.mmerc.al software. The molec.lar c.mposition of this solution is a required input parameter. The fac. spec.fic.diffusion c.effic.ent of the solid （c.ystal surfac.） and liquid （solution） system is determined using the molec.lar dynamic. proc.dure. The obtained diffusion c.effic.ent is related to the spec.fic.fac. growth rate via the attac.ment energy of the pure morphology. The signific.nt improvements are ac.ieved in the morphology predic.ion bec.use the investigation on the fac. growth rates in a c.mplex growth environment （as multi-c.mponent solutions with additives） c.n be c.rried out based on the diffusion c.effic.ents.

Elec.ro-osmotic.flow of a sec.nd-grade fluid in a porous mic.oc.annel subj.c. to an Ac.elec.ric.field

Studies on elec.ro-osmotic.flows of various types of fluids in mic.oc.annel are of great importanc. owing to their multifold applic.tions in the transport of liquids, partic.larly when the ionized liquid flows with respec. to a c.arged surfac. in the presenc. of an external elec.ric.field. In the c.se of visc.elastic.fluids, the volumetric.flow rate differs signific.ntly from that of Newtonian fluids, even when the flow takes plac. under the same pressure gradient and the same elec.ric.field. With this end in view, this paper is devoted to a study c.nc.rning the flow pattern of an elec.ro-osmotic.flow in a porous mic.oc.annel, whic. is under the ac.ion of an alternating elec.ric.field. The influenc. of various rheologic.l and elec.ro-osmotic.parameters, e.g., the Reynolds number, Debye-Huc.el parameter, shape fac.or and fluid visc.elastic.ty on the kinematic. of the fluid, has been investigated for a sec.ndgrade visc.elastic.fluid. The problem is first treated by using analytic.l methods, but the quantitative estimates are obtained numeric.lly with the help of the software MATHEMATIc.. The results presented here are applic.ble to the c.ses where the c.annel height is muc. greater than the thic.ness of the elec.ric.l double layer c.mprising the Stern and diffuse layers. The study reveals that a larger value of the Debye-Huc.el parameter c.eates sharper profile near the wall and also that the veloc.ty of elec.ro-osmotic.flow inc.eases as the permeability of the porous mic.oc.annel is enhanc.d. The study further shows that the elec.ro-osmotic.flow dominates at lower values of Reynolds number. The results presented here will be quite useful to validate the observations of experimental investigations on the c.arac.eristic. of elec.ro-osmotic.flows and also the results of c.mplex numeric.l models that are nec.ssary to deal with more realistic.situations, where elec.ro-osmotic.flows c.me into the pic.ure, as in blood flow in the mic.o-c.rc.latory system subj.c. to an elec.

c.al Washing Exploration in India dates bac. to 1900s; though, first c.king c.al washeries in India were installed after independenc.. At present, most of the c.king c.al washeries are owned by public.Sec.or c.mpanies; whereas, most of the non-c.king c.al washeries are owned by private Sec.or. Even after six dec.des of c.al washing prac.ic.s, there has not been signific.nt development in the c.al washing intelligentsia. Indian c.al Washing industry is still dependent on imported equipment, whic. has been designed to treat c.al that is signific.ntly different from Indian c.al of drift origin. In this paper, authors have ventured into evolution of Indian c.al Washing Industry （with a foc.s on c.king c.al washing sec.or）, its present c.ndition and future prospec. for growth. The paper emphasizes need for developing indigenous solutions to industrial c.allenges and highlights importanc. of inc.eased c.ordination among ac.demia-researc. institutions and c.al industry.

Nearly all inf-sup stable mixed finite elements for the inc.mpressible Stokes equations relax the divergenc. c.nstraint. The pric. to pay is that a priori estimates for the ve- loc.ty error bec.me pressure-dependent, while divergenc.-free mixed finite elements de- liver pressure-independent estimates. A rec.ntly introduc.d new variational c.ime using lowest-order Raviart-Thomas veloc.ty rec.nstruc.ions delivers a muc. more robust modi- fied c.ouzeix-Raviart element, obeying an optimal pressure-independent disc.ete H1 ve- loc.ty estimate. Refining this approac., a more sophistic.ted variational c.ime employing the lowest-order BDM element is proposed, whic. also allows proving an optimal pressure- independent L2 veloc.ty error. Numeric.l examples c.nfirm the analysis and demonstrate the improved robustness in the Navier-Stokes c.se.

Mountain ec.system, on the earth, has plenty of natural resourc.s. In Himac.al pradesh all the rivers are snowfed and therefore ric. in water resourc.s. These resourc.s have been supporting enough for the generation of elec.ric.ty through introduc.ng hydropower proj.c.s sinc. the last dec.de However, every developmental ac.ivity has its own negative impac.s on the surrounding environment. Due to the fragile nature of topography and delic.c. of ec.logy of the Himalaya, it results in lot of disturbanc.s bec.use of high degree of human interferenc.s like c.nstruc.ion of maj.r hydropower proj.c.s. The inc.eased extent of geologic.l hazards, suc. as landslides, roc. fall and soil erosion, have mainly due to alike developmental interventions in the natural ec.system. So understanding and analysing suc. impac.s of the hydropower proj.c.s have mainly been on the environment in various forms but natural hazards have been frequent ones. The present study, therefore, foc.ses mainly on the parbati Stage II （800 MW） and the parbati Stage III （520 MW） hydropower proj.c.s; both of whic. fall within the Kullu distric. of Himac.al pradesh. Based on the perc.ption survey of the loc.l c.mmunities, the existing land use pattern, status of total ac.uired land of the residents by hydropower proj.c.s, frequent natural hazards and resultant loss to the loc.l c.mmunities due to upc.ming c.nstruc.ion of hydropower proj.c.s surrounding to the parbati Stage II and III have been analysed in the paper. Also, the preventive measures to mitigate these adverse impac.s have been suggested to strengthen these proj.c.s in ec.-friendly manner in the mountain c.ntext.

The photo-dissoc.ation dynamic. of LiF is investigated with newly c.nstruc.ed ac.urate ab initio potential energy c.rves （pEc.） using the time-dependent quantum wave pac.et method. The osc.llations and dec.y of the wave pac.et on the adiabats as a func.ion of time are given, whic. c.n be c.mpared with the femtosec.nd transition-state （FTS） spec.rosc.py. The photo-absorption spec.ra and the kinetic.energy distribution of the dissoc.ation fragments, whic. c.n exhibit the vibration-level struc.ure and the dispersion of the wave pac.et, respec.ively, are also obtained. The investigation shows a blue shift of the band c.nter for the photo-absorption spec.rum and multiple peaks in the kinetic.energy spec.rum with inc.easing laser intensity, whic. c.n be attributed to external field effec.s. By analyzing the osc.llations of the wave pac.et evolving on the upper adiabat, an approximate inversion sc.eme is devised to roughly deduc. its shape.
