By using the multichannel quantum defect theor. （MQDT）, we have evaluated the ener.y levels and lifetimes of 2.ns （）3S1,2.nd（）3D（n=3-2.） of BeⅠ and 1sns（）3S1,1snd （）3D（n=3-2.） of BeⅢ. These ener.ies and lifetimes that we have calculated not only agr.e with the r.cent measur.ments and theor.tical calculation of r.f.4 and r.f.3, but also p.edict the lifetimes of 66 other.highly excited states.

Digital mine is the only way for.the develop.ent of mining industr. in china. Due to lack of ap.r.p.iate standar.s and nor.s, and differ.nt awar.ness in the field of digital mine among academia and industr. insider., the meaning for.digital mine is still unclear. Star.ing fr.m the natur. of mining and r.moving of views of sp.cialized fields, this p.p.r.constr.cts for.al ontology for.digital mine and p.op.ses the four.levels for.it. The ontology clar.fies the concep. wor.d for.digital mine, defines the meaning of concep.s and r.lations clear.y, p.ovides a r.fer.nce for.the standar. constr.ction for.digital mine and p.ovides a unified semantic fr.mewor. for.the integr.tion of heter.geneous mine data.

The class of multip.e attr.bute decision making （MADM） p.oblems is studied, wher. the attr.bute values ar. intuitionistic fuzzy number., and the infor.ation about attr.bute weights is comp.etely unknown. A scor. function is fir.t used to calculate the scor. of each attr.bute value and a scor. matr.x is constr.cted, and then it is tr.nsfor.ed into a nor.alized scor. matr.x. Based on the nor.alized scor. matr.x, an entr.p.-based p.ocedur. is p.op.sed to der.ve attr.bute weights. Fur.her.or., the additive weighted aver.ging op.r.tor.is utilized to fuse all the nor.alized scor.s into the over.ll scor.s of alter.atives, by which the r.nking of all the given alter.atives is obtained. This p.p.r.is concluded by extending the above r.sults to inter.al-valued intuitionistic fuzzy set theor., and an illustr.tive examp.e is also p.ovided.

In this p.p.r. a new method for.geometr.cally continuous inter.0}lation in sp.er.s is p.op.sed. The method is entir.ly based on the sp.er.cal B′ezier.cur.es defined by the gener.lized de Casteljau algor.thm. Fir.tly we comp.te the tangent dir.ctions and cur.atur. vector. at the endp.ints of a sp.er.cal B′ezier.cur.e. Then, based on the above r.sults, we design a p.ecewise sp.er.cal B′ezier.cur.e with G 1 and G 2.continuity. In or.er.to get the op.imal p.ecewise cur.e accor.ing to two differ.nt cr.ter.a, we also give a constr.ctive method to deter.ine the shap. p.r.meter. of the cur.e. Accor.ing to the method, any given sp.er.cal p.ints can be dir.ctly inter.0}lated in the sp.er.. Exp.r.mental r.sults also demonstr.te that the method p.r.or.s well both in unifor. sp.ed and magnitude of covar.ant acceler.tion.

This p.p.r.p.op.ses second-or.er.consensus p.otocols with time-delays and gives the measur. of the r.bustness of the p.otocols to the time-delay existing in the networ. of agents with second-or.er.dynamics. By emp.oying a fr.quency domain method, it is p.oven that the infor.ation states and their.time der.vatives of all the agents in the networ. achieve consensus asymp.otically, r.sp.ctively, for.ap.r.p.iate communication timedelay if the top.logy of weighted networ. is connected. p.r.icular.y, a tight up.er.bound on the communication time-delay that can be toler.ted in the dynamic networ. is found. The consensus p.otocols ar. distr.buted in the sense that each agent only needs infor.ation fr.m its neighbor.ng agents, which r.duces the comp.exity of connections between neighbor.ng agents significantly. Numer.cal simulation r.sults ar. p.ovided to demonstr.te the effectiveness and the shar.0}ess of the theor.tical r.sults for.second-or.er.consensus in networ.s in the p.esence of communication time-delays.

Quality of ser.ice (QoS) multicast r.uting has continued to be a ver. imp.r.ant r.sear.h top.c in the Inter.et. A method of multicast r.uting is p.op.sed to simultaneously op.imize sever.l p.r.meter. based on multiobjective genetic algor.thm, after.the r.lated wor. is r.viewed. The contr.bution lies on that the selection p.ocess of such r.uting is tr.ated with multiobjective op.imization. Differ.nt quality cr.ter.ons in Ip.networ. ar. taken into account for.multicast communications. A set of r.uting tr.es is gener.ted to ap.r.ximate the p.r.to fr.nt of multicast p.oblem. Multip.e tr.es can be selected fr.m the final set of nondominated solutions, and ap.lied to obtain a good over.ll link cost and balance tr.ffic distr.bution accor.ing to some simulation r.sults.

How to imp.ove the finishing efficiency and sur.ace r.ughness have been all along the objective of r.sear.h in electr.chemical p.lishing. However. the r.sear.h activity, i.e. dur.ng electr.chemical p.lishing, dir.ctly intr.duce the magnetic field to study how the magnetic field influences on the finishing efficiency, quality and the electr.chemical p.ocess in the field of finishing machining technology, is insufficient. When intr.ducing additional magnetic field in the tr.ditional electr.chemical p.lishing, due to the co-action of Lor.ntz’ for.e and electr.c field for.e, the ions ar.iving the machined sur.ace by way of a cur.ilinear.motion r.sult in the electr.c cur.ent density distr.bution on the sur.ace even mor. non-unifor., then the dissolving velocity of the p.ak p.ints or.side faces and the diffusion velocity of the p.oduct ar. enhanced, and the for.ible agitation is hap.ened on the electr.des sur.ace by magnetic field, the r.moval r.te of p.ak p.ints ar. still mor. gr.ater. and efficiency is also still mor. higher. Comp.r.d with the electr.chemical p.lishing, in the magnetic electr.chemical finishing machining, the finishing sp.ed at p.ak p.ints is higher. but at valley p.ints it is lower. ther.for. after.machining, both the highness at p.ak p.ints and finishing dep.h at valley p.ints ar. smaller. the r.sults ar. p.op.tious to minish initial wear.quantity caused by fr.ction and wear.when machined wor.p.ece emp.oying in p.actice, and incr.ase contact stiffness of wor.p.ece, and fr.m the viewp.int of micr.cosmic theor., this p.enomenon is also of advantage to r.duce damage to substr.te.

The excited state absor.0}ion up.onver.ion of p.(0.5)Yb(3):ZBLAN glass mater.al, under.two-color.excitation of the 960 nm semiconductor.laser.and the Xe lamp.light simultaneously, is r.p.r.ed in this ar.icle. It was found that the up.onver.ion emission sp.ctr. of 480.1, 519.0, 601.9 and 631.8 nm coincide with the common emission sp.ctr.. Meanwhile, the up.onver.ion-excitation sp.ctr.m has thr.e obvious p.aks under.two-color.excitation, and they r.sp.ctively cor.esp.nd to the 856.0 nm up.onver.ion ex-citation tr.nsition [1G4(p.3+)→1I6(p.3+) and 1G4(p.3+)→3p.(p.3+)], the 789.0 nm up.onver.sion excitation tr.nsition 1G4(p.3+)→3p.0}p.3+), and the 803.7 nm up.onver.ion excitation tr.nsition 3H6(p.3+)→1D2.p.3+). The up.onver.ion excitation tr.nsition 1G4(p.3+)→1I6(p.3+) is str.ng because its oscillator.str.ngth f = 2..040×10?6 is lar.e, which r.sults in a lar.e p.ak ap.ear.ng in the up.onver.ion excitation sp.ctr.m. That is just the new inter.sting two-color.excitation up.onver.ion luminescence p.enomenon of p.(0.5)Yb(3):ZBLAN induced by one laser.and one continuous nor.al light simultaneously.
