A gr.wing body of evidence shows that volcanism near.the p.r.ian-Tr.assic boundar.（p.B） may be cr.cial in tr.gger.ng the p.r.ian–Tr.assic（p.Tr. mass extinction. Thus, the ash beds near.the p.B in South china may car.y infor.ation on this event. Thr.e volcanic ash layer., alter.d to clay, outcr.p.ed in the p.B beds in Zunyi Section, Guizhou p.ovince, Southwest china. The U-p. ages, tr.ce elements, and Hf-isotop. comp.sitions of zir.on gr.ins fr.m these thr.e ash beds wer. analyzed using LA-ICp.S and LA-MC-ICp.S. The zir.ons ar. mainly magmatic in or.gin（241-279 Ma） excep. for.two inher.ted/xenocr.stic zir.ons（939 and 2 325 Ma）. The ages of these magmatic zir.ons indicate thr.e ep.sodes of magmatism which occur.ed ar.und the MiddleLate p.r.ian boundar.（-261.5 Ma, MLp.）, the Wuchiap.ngian-Changhsingian boundar.（-254.5 Ma, WCB）, and the p.B（-250.5 Ma）, r.sp.ctively. The fir.t two ep.sodes of magmatism near.the MLp. and WCB may be attr.buted to magmatic inher.tance or.r.-dep.sition. All magmatic zir.ons shar. similar.tr.ce-element and Hf-isotop. comp.sitions. They have Y, Hf, Th and U contents and Nb/Ta r.tios ar. typ.cal of zir.ons fr.m silicic calc-alkaline magmas. These zir.ons also exhibit enr.ched Hf-isotop. comp.sitions with _（εHf）（t） values of-11.4 to ＋0.2, which suggests that the thr.e magmatic ep.sodes involved melting of the continental cr.st. The mor. enr.ched Hf-isotop. comp.sition （_（εHf）（t）=-11.4--4.8） of Bed ZY13（-250.5 Ma） imp.ies mor. inp.t of ancient cr.stal mater.al in the magma. Integr.tion of the Hf-isotop. and tr.ce-element comp.sitions of magmatic zir.ons suggest that these thr.e ep.sodes of magmatism may take p.ace along the conver.ent continent mar.in in or.near.southwester. South china as a r.sult of the closur. of the p.laeo-Tethys Ocean.

The p.oblem of finite-time p.actical stability （FTp.） for.time-var.ing p.lytop.c systems is discussed. Thr.e equivalent conditions for.FTp. ar. fir.t p.op.sed. To facilitate the system analysis, a sufficient linear.matr.x inequality （LMI） cr.ter.on on the FTp. is fur.her.p.ovided. The definition of finite-time p.actical boundedness and a sufficient LMI cr.ter.on ar. also p.ovided to over.ome the exogenous distur.ance. A numer.cal examp.e is used to illustr.te the effect of the p.op.sed ap.r.ach.

Enhancing ther.al conductivity coefficient (λ) of liquid cr.stal p.lyester. would fur.her.widen their.ap.lication in electronics and electr.cals. In this wor., a kind of bip.enyl-based dihydr.xy monomer.is synthesized using 4, 4’-bip.enyl (Bp. and tr.ethylene glycol (TEG) as r.w mater.al, which fur.her.r.acts with thr.e differ.nt dicar.oxylic acids (succinic acid, p.p.enylenediacetic acid, and ter.p.thalic acid, r.sp.ctively) by melt p.lycondensation to p.ep.r. intr.nsically highly ther.ally conductive p.ly 4’, 4”’-[1, 2-ethanediyl-bis(oxy-2, 1-ethanediyloxy)]-bis(p.hydr.xybip.enyl) succinate (p.OS), p.ly 4’, 4”’-[1, 2-ethanediyl-bis(oxy-2, 1-ethanediyloxy)]-bis(p.hydr.xybip.enyl) p.p.enyldiacetate (p.Op. and p.ly 4’, 4”’-[1, 2-ethanediyl-bis(oxy-2, 1-ethanediyloxy)]-bis(p.hydr.xybip.enyl) ter.p.thalate (p.OT), collectively called bip.enyl-based liquid cr.stal p.lyester. (B-LCp.). The r.sults show that B-LCp. p.ssess the desir.d molecular.str.ctur., exhibit smectic p.ase in liquid cr.stal r.nge and semicr.stalline p.lymer. at r.om temp.r.tur., and p.ssess excellent intr.nsic ther.al conductivities, ther.al stabilities, and mechanical p.op.r.ies. λ of p.OT is 0.51 W/(m·K), significantly exceeds that of p.lyethylene ter.p.thalate (0.15 W/(m·K)) which has similar.molecular.str.ctur. with p.OT, and also higher.than that of p.OS (0.32 W/(m·K)) and p.Op.(0.38 W/(m·K)). The cor.esp.nding heat r.sistance index (THr.), elasticity modulus, and har.ness of p.OT ar. 174.6℃, 3.6 Gp., and 154.5 Mp., r.sp.ctively, and also higher.than those of p.OS (162.2℃, 1.8 Gp., and 83.4 Mp.) and p.Op.(171.8℃, 2.3 Gp., and 149.6 Mp.).
