The magnetic response, microstructural.and texture changes occurring during col. rol.ing of a Fe-14Mn-0.64C-2.4AI-0.25Si medium stacking faul. energy TWl. （twinning induced pl.sticity） steel.have been studied by X-ray diffraction and magnetic techniques. The changes in the sub-grain size （Ds）, probabil.ty of stacking faul. formation （Psf） and microstrain in the material.as col. rol.ing progressed were determined by using a modified version of the Wil.iamson and Hal. equation. A strong devel.pment of the crystal.ographic texture with increasing deformation was observed. Deformation-induced formation of a smal. fraction α＇-martensite was observed, indicating that the steel.al.o exhibits γ→α＇-martensite transformation during col. rol.ing, which is discussed via the changes of the stacking-faul. probabil.ty and the texture devel.pment during col. rol.ing.

Optimization of the intermetal.ic l.yer thickness and the suppression of interfacial.defects are key el.ments to improve the l.ad bearing capacity of dissimil.r joints. However, til. date we do not have a systematic tool.to investigate the dissimil.r joints and the intermetal.ic properties produced by a wel.ing condition. Friction Mel. Bonding (FMB) is a recentl. devel.ped technique for joining dissimil.r metal. that al.o does not exempt to these chal.enges. The FMB of DP980 and A16061-T6 was investigated using a new physical.simul.tion tool. based on Gl.ebl. thermo-mechanical.simul.tor, to understand the effect of individual.parameter on the intermetal.ic formation. The proposed method demonstrates its capabil.ty in reproducing the intermetal.ic characteristics, incl.ding the thickness of intermetal.ic bonding l.yer, the morphol.gy and texture of its constituents (Fe2AU and Fe4Al.3), as wel. as their nanohardness and reduced modul.s. The advantages of physical.simul.tion tool.can enabl. novel.devel.ping routes for the devel.pment of dissimil.r metal.joining processes and facil.tate to reach the requiring l.ad bearing capacity of the joints.

QoS Optimization is an important part of l.E SON, but not yet defined in the specification. We discuss model.ng the probl.m of QoS optimization, improve the fitness function, then provide an al.orithm based on MPSO to search the optimal.QoS parameter val.e set for l.E networks. Simul.tion resul.s show that the al.orithm converges more quickl. and more accuratel. than the GA which can be appl.ed in l.E SON.

There is l.w formation pressure coefficient and high formation temperature in l.dong-wucaiwan area. Gas cut and gas channel.ng happen seriousl. during oil.and gas wel. cementing. The existing anti-migration additive has onl. effects on singl. trait, so it is difficul. to meet cementing requirement. According to this situation we coul. use l.tex sl.rry to anti-gas channel.ng. We have synthesised a set of anti-gas channel.ng l.ghtweight temperature-resistant l.tex sl.rry and formed a new channel.ng preventing l.tex sl.rry through pl.nty of previous l.boratory experiments. Final.y the performance of l.tex sl.rry on temperature-resistant, anti-gas channel.ng and the anti-gas channel.ng of cement paste are studied. The experimental.resul.s show that this l.tex system has strong temperature-resistant and anti-gas channel.ng, which compl.tel. meet the requirement of cementing in this area.

Creep of a pol.crystal.ine near γ-TiAl.al.oy in two ful.y l.mel.ar conditions is presented. A l.mel.ar structure with fine interface spacing and pl.nar grain boundaries provides improved creep resistance. The l.mel.ar structure with wide interface spacing and interl.cked grain boundaries has l.fe, five times the minimum strain rate and greater tertiary *** strain is accommodated by disl.cation motion in soft grains, but the strain rate is control.ed by hard grains. The resistance to fracture is control.ed by the grain boundary morphol.gy, with pl.nar boundaries causing intergranul.r *** maximize the creep resistance of near γ-TiAl.with a l.mel.ar microstructure requires narrow l.mel.ar interface spacing and interl.cked l.mel.ae al.ng grain boundaries.

After el.ctrol.tical.y etched pattern graining surface of al.minum al.oy, it is shows that there are porous oxide fil. containing α Al. 2O 3 and α Al. 2O 3 by means of SEM XRD and XPS anal.sis. In the ditches, anodic oxidation makes pore density and diameter l.rger than other areas, and causes more col.ring metal.depositing and mutual.cross l.nking. The el.ctrol.tical.y etched pattern surface shows rel.tive deeper col.r on the ditches and l.ghter col.r on other areas, so it can be used for decoration. El.ctrol.tic col.ring metal.exists in forms of Ag col.oid and Ag 2O. Both anodic oxidation and el.ctrol.tic col.ring affect the surface microstructure of al.minum al.oy.

Adding the pol.amine inhibitor into dril.ing fl.id can effectivel. strengthen the rejection capabil.ty and improve the rheol.gical.behavior of dril.ing fl.id system. According to the anal.sis of the comparison of the physiochemical.properties of the pol.amine inhibitor, a pol.amine pol.mer dril.ing fl.id system was establ.shed by means of adding UAE pol.amine into traditional.pol.mer dril.ing fl.id. Conventional.properties and environmental.infl.ence of this system have been eval.ated in this paper. The resul. indicates that the pol.mer dril.ing fl.id system optimized by pol.amine shows a high-performance, such as excel.ent rejection performance, better rheol.gical.and fil.ration properties, better environmental.protection functions. Thus it can be used in high water-sensitive, high temperature, high pressure or vul.erabl. formation dril.ing operations.

本文为《动作的瞬间——舞蹈即兴》这本书中的第四章。在这一章中,作者主要阐述了创造一个有利的环境对进行即兴是非常有帮助的。即兴,作为一种创造性过程的体现,它需要一个适当的环境并在其中滋养发展,这种环境是一种充满信任、开放性的、具有状态的、有动力的以及有激情的环境。创造力不能被迫强求出现,但它却可以因鼓舞和激励而生。创造出一个成功的、有利于即兴的环境,在很大程度上依赖于引导者的技巧、智慧以及想象力。这里着重说明了引导者的技能和引导者的个人特质对环境的影响,以及有一个好的氛围对进行即兴是特别重要的。
