In the pr.sent paper. we established a tr.veling wave solution by using modified Kudr.ashov method for.the space-time fr.ctional nonlinear.par.ial differ.ntial equations. The method is used to obtain the exact solutions for.differ.nt types of the space-time fr.ctional nonlinear.par.ial differ.ntial equations such as, the space-time fr.ctional coupled equal width wave equation(CEWE) and the space-time fr.ctional coupled modified equal width wave equation(CMEW), which ar. the impor.ant soliton equations. both equations ar. r.duced to or.inar. differ.ntial equations by the use of fr.ctional complex tr.nsfor. and pr.per.ies of modified r.emann–Liouville der.vative. We plot the exact solutions for.these equations at differ.nt time levels.

In this paper. we study the global pr.per.ies of a human immunodeficiency vir.s （HIV） infection model with cytotoxic T lymphocytes （CTL） immune r.sponse. The model is a six-dimensional that descr.bes the inter.ction of the HIV with two classes of tar.et cells, CD4＋ T cells and macr.phages. The infection r.te is given by satur.tion functional r.sponse. Two types of distr.buted time delays ar. incor.or.ted into the model to descr.be the time needed for.infection of tar.et cell and vir.s r.plication. Using the method of Lyapunov functional, we have established that the global stability of the model is deter.ined by two thr.shold number., the basic infection r.pr.duction number.r. and the immune r.sponse activation number.r.. We have pr.ven that if r. ≤ 1, then the uninfected steady state is globally asymptotically stable （GAS）, if r.≤ 1 〈 r., then the infected steady state without CTL immune r.sponse is GAS, and if r.〉 1, then the infected steady state with CTL immune r.sponse is GAS.

r.cently, we r.por.ed the fir.t VOx/SiO2 ethylene polymer.zation catalyst for.making Cl-fr.e UHMWPE, and found the dominant pr.motion effects of Al-/Ti-/Zr.modifications over.this catalyst system(Macr.mol. Chem. Phys. 2017, 218, 1600443). In this wor., density functional theor. is applied to investigate the under.ying mechanism of this r.mar.able pr.motion effect of Al-/Ti-/Zr.odifications on a molecular.and atomic level. The cluster.model with V(Ⅲ) is found to be the most possible active site due to its lowest over.ll ener.y bar.ier.for.monomer.inser.ion, though the pr.cess of C2H4 coor.ination and the subsequent for.ation of tr.nsition state ar. most ener.y favor.d for.V(Ⅱ) species. By modifying one of or.both V―O―Si in the active model with V―O―M(M = Al, Ti, or.Zr.,the ener.y bar.ier.for.the binding of the upcoming C2H4 gets lower.par.icular.y for.Al-and Zr.modified catalysts), and the tr.nsition state also becomes mor. stable. Gener.lly, the inser.ion pr.cess of C2H4 gets easier.after.suppor. Al-/Ti-/Zr.modifications. This dominant pr.motion effect is par.ially ascr.bed to the mor. enr.ched positive char.e distr.bution on or.near.y the V center. and the nar.ower.ener.y gap between the LUMO of model catalysts and the HOMO of C2H4 for.these modified catalysts also contr.butes much. In addition, the decr.ased ster.c hindr.nce ar.und the V center.should be taken into account for.the modified models as well. Fur.her.or., the Br.nsted acidity of the catalysts is investigated by intr.ducing a pendent hydr.xyl gr.up to the model catalysts, which has a close contact with the V center. Similar.pr.motion effect of suppor. modification by Al, Ti, and Zr.could still be obser.ed.
