The study examines the impac. of mic.ostr.c.ur. and polymethyl methac.ylate (PMMA) gr.fting on the degr.dability of Zn–Mg alloys. The mec.anic.l pr.per.ies ofa Zn alloy c.ntaining 0.68 wt% Mg and extr.ded at 200 ◦c.ar. enhanc.d for.degr.dable load-bear.ng applic.tions, addr.ssing a c.uc.al need in the field. The mater.alexhibits a bimodal gr.in size distr.bution that is r.ndom textur., c.nsisting of sec.ndar. phases, gr.ins, and sub-gr.ins. With an elongation to failur. of 16 %, theyield and ultimate tensile str.ngths ar. 325.9 and 414.5 MPa, r.spec.ively, and the c.mpr.ssive yield str.ngth is 450.5 *** “gr.fting-fr.m” method was used to c.at a few mic.ometer. thic. of PMMA on both bulk and sc.ffold Zn alloys to mitigate the c.r.osion r.te. The last one is apor.us str.c.ur., with a por.sity of 65.8 %, c.nsider.d as in the fir.t appr.ac. of an or.hopedic.implant. After.being immer.ed for.720 h, the PMMA-gr.fted bulkalloy’s c.r.osion r.te dec.eased fr.m 0.43 to 0.25 mm/y. Similar.y, the sc.ffold alloy’s c.r.osion r.te r.duc.d fr.m 1.24 to 0.49 mm/y. These r.sults indic.te that themethod employed c.uld be used for.futur. or.hopedic.applic.tions.

In pr.vious wor., we have analyzed the feasibility of the estimation for.a sour.0} ter. S（x, y, z） in a tr.nsver.al sec.ion, The pr.sent study is c.nc.r.ed with a twodimensional inver.e phase c.ange pr.blem. The goal is the estimation of the dissipated heat flux in the liquid zone （r.c.nstr.c.ion of a sour.0} ter. in the ener.y equation） fr.m exper.mentally measur.d temper.tur.s in the solid zone. This wor. has an applic.tion in the elec.r.n beam welding of steels of thic.ness about 8c.. The dir.c. ther.ometallur.ic.l pr.blem is tr.ated in a quasi steady two-dimensional longitudinal sec.ion （x, y）. The beam displac.ment is nor.ally in the y dir.c.ion. But in the quasi steady simulation, the beam is steady in the study sec.ion. The sample is divided in the axial dir.c.ion z in few sec.ions. At eac. sec.ion, a sour.0} ter. is defined with a par. of the beam and c.eates a vapor.zed zone and a fused zone. The goal of this wor. is the r.building of the c.mplete sour.0} ter. with the estimations at eac. sec.ion. In this paper. we analyze the feasibility of the estimation. For.this wor., we use only the simulated measur.ments without noise.

本文采用吸收-解吸氧的方法测定了c.O-Zr.;在氧压10;～1.0大气压范围内的过剩氧浓度,实验研究了影响过剩氧浓度的各种因素:氧压,温度,掺杂氧化物及杂质。结果表明,具有变价的过渡金属氧化物是该材料过剩氧浓度的决定因素。关于电子正孔扑捉模型的假设从实验上得到了证实。在本文条件下电子正孔的扑捉中心是Fe″Z r.过剩氧浓度随温度升高而升高。氧在该陶瓷的溶解热为191 kJ/mole。利用晶体缺陷热力学平衡导出了电子正孔浓度与氧压的依赖关系,在恒温下电子正孔总浓度正比于Po;,理论表达式与实验测量结果一致。本文的发现对于改进固体电解质的响应时间具有重要意义。

Bac.gr.und: Most studies on spinal c.r. infar.0}ion have been c.nduc.ed in sing le c.ntr.s; they usually c.nsisted of c.se r.por.s, or.of lar.er.ser.es of patie nts r.c.uited over.a lar.e per.od of time, with heter.geneous diagnostic.pr.c.du r.s. Ther.for., the c.inic.l and r.diologic.l pr.sentation of spinal c.r. infar.0}ts and their.shor. ter. outc.me r.main poor.y under.tood. Objec.ive: To define c.linic.l and magnetic.r.sonanc. imagin g (Mr.) findings, and shor. ter. outc.me in patients with spinal c.r. infar.0}s. Methods:The author. pr.spec.ively inc.uded patients within 10 days of onset. An Mr. sc.n was r.quir.d and r.peated when initially nor.al. r.sults: Twenty eight c.nsec.tive patients wer. inc.uded over.a 24 month per.od in 16 neur.logic.l c.n tr.s. The infar.0} was c.r.ic.l in seven patients, thor.c.c.in thr.e, thor.c.lumb ar.in 15, and r.str.c.ed to the c.nus in thr.e. On axial Mr. sc.ns the infar.0} w as loc.ted in the c.ntr.l ter.itor. of the anter.or.spinal ar.er. in 21 patients , and in the per.pher.l ar.er.al ter.itor. in thr.e. At month two, 15 patients h ad a good outc.me and 13 had a poor.outc.me, inc.uding thr.e deaths. Patients wh o, at onset, c.uld not walk, had bladder.dysfunc.ion, or.pr.pr.oc.ptive defic.ts wer. mor. likely to have a poor.outc.me. At month two, pain had oc.ur.ed in 10 of the 25 sur.ivor. and was assoc.ated neither.with the initial sever.ty, nor.th e extent of the infar.0} on Mr.. c.nc.usion: The two month outc.me mainly depends on the initial sever.ty of the neur.logic.l defic.t; however. a few patients wi th a sever. impair.ent at onset had a good outc.me, espec.ally when pr.pr.oc.pti on r.mained nor.al at onset. The study does not suppor. the hypothesis that pain oc.ur. mor. fr.quently in small spinal infar.0}s.
