This pape. is conce.ne. with de.e.oping accurate.and e.ficie.t nume.ical me.hods for one.dime.sional fully nonline.r se.ond orde. e.liptic and parabolic partial diffe.e.tial e.uations （PDe.）. In the.pape. we.pre.e.t a ge.e.al frame.ork for constructing high orde. inte.ior pe.alty discontinuous Gale.kin （IP-DG） me.hods for approximating viscosity solutions of the.e.fully nonline.r PDe.. In orde. to capture.discontinuitie. of the.se.ond orde. de.ivative.uxx of the.solution u, thre. inde.e.de.t functions p1,p2 and p3 are.introduce. to re.re.e.t nume.ical de.ivative. using various one.side. limits. The.propose. DG frame. work, which is base. on a nonstandard mixe. formulation of the.unde.lying PDe. e.be.s a nonline.r proble. into a mostly line.r syste. of e.uations whe.e.the.nonline.rity has be.n modifie. to include.multiple.value. of the.se.ond orde. de.ivative.uxz. The.propose. frame.ork e.te.ds a companion finite.diffe.e.ce.frame.ork de.e.ope. by the.authors in [9] and allows for the.approximation of fully nonline.r PDe. using high orde. polynomials and non-uniform me.he.. In addition to the.nonstandard mixe. formulation se.ting, anothe. main ide. is to re.lace.the.fully nonline.r diffe.e.tial ope.ator by a nume.ical ope.ator which is consiste.t with the.diffe.e.tial ope.ator and satisfie. ce.tain monotonicity （calle. g-monotonicity） prope.tie.. To e.sure.such a g-monotonicity, the.crux of the.construction is to introduce.the.nume.ical mome.t, which plays a critical role.in the.propose. DG frame. work. The.g-monotonicity give. the.DG me.hods the.ability to se.e.t the.mathe.atically ＂corre.t＂ solution （i.e., the.viscosity solution） among all possible.solutions. More.ve., the.g-monotonicity allows for the.possible.de.e.opme.t of more.e.ficie.t nonline.r solve.s as the.spe.ial nonline.rity of the.alge.raic syste.s can be.e.plore. to de.ouple.the.e.uations.

近年来,汽车产业内部要求应用的材料需要具有高表观硬度、高淬透性以及提高力学性能。这些往往-矛盾的要求迫使寻找开发新材料,这些新材料必须不增大后续热处理的费用,能够提供较高的烧结态表观硬度及良好的静态/动态力学性能。传统的烧结硬化材料虽然提供适用的表观硬度,但力学性能与烧结体密度却不高。本文将用许多文献资料证明,一系列烧结硬化材料既有好的压缩性、高表观硬度,又能增高力学性能。将着重讨论这些材料在汽车(包括发动机与变速器)的,诸如齿轮、凸轮及链轮中的应用。这些零件当前是用压制-烧结-热处理工艺,或者是用常规的铸锻材料-切削加工制造的。还将讨论用高温烧结来强化生产工艺。
