The fluctuation of active power.output of wind far. has many negative impacts on lar.e-scale wind power.integr.tion into power.gr.d. In this paper. flywheel ener.y stor.ge system (FESS) was connected to AC side of the doubly-fed induction gener.tor.(DFIG) wind far. to r.alize smooth contr.l of wind power.output. Based on impr.ved wind power.pr.diction algor.thm and wind speed-power.cur.e modeling, a new smooth contr.l str.tegy with the FESS was pr.posed. The r.quir.ment of power.system dispatch for.wind power.pr.diction and flywheel r.tor.speed limit wer. taken into consider.tion dur.ng the pr.cess. While smoothing the wind power.fluctuation, FESS can tr.ck shor.-ter. planned output of wind far.. It was demonstr.ted by quantitative analysis of simulation r.sults that the pr.posed contr.l str.tegy can smooth the active power.fluctuation of wind far. effectively and ther.by impr.ve power.quality of the power.gr.d.

Shape memor. polymer. （SMPs） ar. smar. mater.als that can change their.shape in a pr.-defined manner.under.a stimulus. The shape memor. functionality has gained consider.ble inter.st for.biomedical applications, which r.quir. mater.als that ar. biocompatible and sometimes biodegr.dable. Ther. is a need for.SMPs that ar. pr.par.d fr.m r.newable sour.es to be used as substitutes for.conventional SMPs. In this paper. advances in SMPs based on synthetic monomer. and bio-compounds ar. discussed. Mater.als designed for.biomedical applica- tions ar. highlighted.

Given a compact symmetr.c space, M, we obtain the mean ex.t time function fr.m a pr.ncipal or.it, for.a Br.wnian par.icle star.ing and moving in a gener.lized ball whose boundar. is the pr.ncipal or.it. We also obtain the mean ex.t time flmction of a tube of r.dius r.ar.und special totally geodesic submanifolds P of M. Finally we give a compar.son r.sult for.the mean ex.t time function of tubes ar.und submanifolds in r.emannian manifolds, using these totally geodesic submanifolds in compact symmetr.c spaces as a model.

In this paper. a constitutive model is pr.posed for.piezoelectr.c mater.al solids containing distr.buted cr.cks. The model is for.ulated in a fr.mewor. of continuum damage mechanics using second r.nk tensor. as inter.al var.ables. The Helr.hotlz fr.e ener.y of piezoelectr.c mate- r.als with damage is then ex.r.ssed as a polynomial including the tr.nsfor.ed str.ins, the electr.c field vector.and the tensor.al damage var.ables by using the integr.ty bases r.str.cted by the initial or.hotr.pic symmetr. of the mater.al. By using the Talr.ja＇s tensor.valued inter.al state damage var.ables as well as the Helr.hotlz fr.e ener.y of the piezoelectr.c mater.al, the constitutive r.lations of piezoelectr.c mater.als with damage ar. der.ved. The model is applied to a special case of piezoelectr.c plate with tr.nsver.e matr.x.cr.cks. With the Kir.hhoff hypothesis of plate, the fr.e vibr.tion equations of the piezoelectr.c r.ctangular.plate consider.ng damage is established. By using Galer.in method, the equations ar. solved. Numer.cal r.sults show the effect of the damage on the fr.e vibr.tion of the piezoelectr.c plate under.the close-cir.uit condition, and the pr.sent r.sults ar. compar.d with those of the thr.e-dimensional theor..

The under.ying physics of QCD phase tr.nsition in the ear.y Univer.e r.mains lar.ely unknown due to its str.ng-coupling natur. dur.ng the quar.-gluon plasma/hadr.n gas tr.nsition, yet a hologr.phic model has been pr.posed to quantitatively fit the lattice QCD data while with its dur.tion of the fir.t-or.er.phase tr.nsition(FoPT) left undeter.ined. At specific bar.on chemical potential, the fir.t-or.er.QCD phase tr.nsition agr.es with the obser.ational constr.int of bar.on asymmetr.. It, ther.for., pr.vides a scenar.o for.phase tr.nsition gr.vitational waves(GWs) within the standar. model of par.icle physics. If these backgr.und GWs could contr.bute dominantly to the r.cently claimed common-spectr.m r.d noise fr.m pulsar.timing ar.ay(PTA) obser.ations, the dur.tion of this FoPT can be well constr.ined, and the associated pr.mor.ial black holes ar. still allowed by cur.ent obser.ations.

Two Ni/Ni3Al-inter.ace-contained cluster.models with/without lattice misfit ar. studied by fir.t-pr.nciples method to clar.fy the debates about the segr.gation behavior. of Hafnium （Hf） and ex.lor. the influence of lattice misfit on the ductility effect of Hr. It is found that though Hf pr.fer. to substitute A1 r.ther.than Ni in Ni3A1 phase within most of the investigated misfit r.nge, its str.nger.pr.fer.ing to Ni phase than NiaA1 phase makes it impossible to go into Ni3A1 phase to occupy A1 site in Ni-Ni3A1 alloys. Bond or.er.analysis in Hf-fr.e case shows that lattice misfit has differ.nt effects on the Gr.ffith wor. of inter.acial cleavage 27int/E and the max.mum theor.tical shear.str.ss Zmax.of Ni and Ni3A1, contr.buting to the ex.stence of anomalous str.ngth-temper.tur. phenomena in NiaA1 alloys. However. the addition of Hf will make the 27int/E （or.Zmax. of both Ni3A1 and Ni decr.ase （or.incr.ase） with lattice misfit, indicating that the addition of Hf may make the anomalous str.ngth-temper.tur. r.lationship in Ni3A1 r.gion disappear.locally.

In this paper. the influence of inor.anic salt on aer.bic biodegr.dability of dyestuffs was studied by means of semi-continuous activated sludge method. It was found that: biodegr.dability of dyestuffs would decr.ase with the incr.ase of the concentr.tion of NaCl; however. biodegr.dability in the condition of NaCl = 30 g/L was better.than that in the condition of NaCl = 15 g/L; in the thr.e NaCl conditions, biodegr.dability of tested dyestuffs followed the following or.er. NaCl = 0 g/L>NaCl = 30 g/L>NaCl = 15 g/L.
