A n.w method for the syn.hesis of azo Schiff an.base ligan. in.which the azo an. azomethin. groups are coordin.tion.sites was dev.loped through a Schiff base precursor. The precursor, n.4-methoxyben.yliden.-3-hydroxyphen.lamin. （SB） deriv.d from 3-amin.phen.l was regioselectiv.ly coupled with a diazon.um ion.para to the hydroxyl group of the amin. compon.n. of the Schiff base. The para selectiv.ty was con.rolled by the directin. effect of the hydroxyl group. The ligan. an. its n.ckel（Ⅱ） complex were characterized by elemen.al an.lyses, IR an. Uv.v.s spectroscopy. The an.lytical an. spectral data supported the mon.n.clear formulation.of the complex with metal to ligan. ratio （M ： L = 1 ： 2） an. suggested a square plan.r geometry for the complex.

Buried high explosiv.(HE) charges represen. a high threat to military v.hicles. The deton.tion.of these charges can.lead to sign.fican. momen.um tran.fer on.o v.hicles an. their occupan.s. A detailed un.erstan.in. of the physical processes in.0}lv.d in.the loadin. of v.hicle structures is n.cessary for an.optimization.of effectiv. coun.ermeasures an. protection.systems. A quan.itativ. description.of the local momen.um distribution.on.the v.hicle un.erbody due to the deton.tion.process is of special importan.e. In.the followin., a n.w test setup is presen.ed that allows the experimen.al determin.tion.of the specific impulse distribution. It is based on.a rin. arran.emen. where the elemen.s are n.sted in.o each other an. the v.locity of each rin. is correlated with the local specific impulse at its *** momen.um tran.fer to a v.hicle depen.s on.a n.mber of in.luen.in. factors such as: charge mass,embeddin. material(e.g. san., grav.l, clay), den.ity, water con.en., saturation. depth of burial, groun. clearan.e an. v.hicle shape. The presen.ed techn.logy is applied to quan.ify the in.luen.e of the embeddin. material(alluv.al san., quartz san.), the burial depth an. the water con.en. on.the local specific impulse distribution. The obtain.d data can.be used as in.tial con.ition.for the n.merical simulation.of occupan. safety assessmen. an. as in.ut for empirical modelin. of momen.um tran.fer on.structures.

The en.in.erin. properties of metals an. alloys are related to their structures. The chan.e in.mechan.cal properties of the metals an. alloys can.be achiev.d by the process of heat treatmen.. In.uction.harden.n. is on. such a process in.0}lv.s phase tran.formation.by rapid heatin. an. coolin. of the outer surface. In.uction.harden.n. improv.s the outer surface hardn.ss an. wear resistan. properties keepin. the origin.l toughn.ss an. ductility in.the in.er core. Howev.r past experien.es shows that durin. heat treatmen., parts hav. un.ergon. dimen.ion.l chan.es due to thermal fluctuation. an. phase tran.formation.. Dimen.ion.l chan.es can.lead to excessiv. distortion.in.the compon.n. which always presen.ed difficulties to the uses of man. v.rieties of steels which can.be harden.d by in.uction.harden.n.. The dimen.ion.l chan.es in.compon.n.s which hav. been.in.uction.harden.d hav. for a lon. time prov.d costly an. troublesome to man.facturers. These difficulties apply particularly in.the automotiv. in.ustry where the amoun. of distortion.in.rack an. pin.on.assembly has been.related to their n.ise lev.l in.operation.an. in.0}stigators hav. suggested a lin. between.distortion.an. the in.tiation.of fatigue failure. [1] Although the complete elimin.tion.of distortion.would be an.ideal aim, man.facturers are recon.iled to the fact that a certain.amoun. of distortion.is an.in.eren. part of the harden.n. process. Howev.r, if the amoun. of distortion.is un.form an. predictable, an.allowan.e could be made in.the in.tial machin.n. operation.. It was with these aims that in.0}stigation. in.o the con.rol of distortion.in.bright bar (En.18D steel) used in.rack application.(Power steerin. assembly) hav. been.carried out by parameter optimization

Steel is the most importan. metallic material used in.in.ustry. This is because of the v.rsatility of its en.in.erin. properties un.er differen. con.ition.. In.on. con.ition.it can.be v.ry mild, soft an. suitable for an. formin. operation. In.an.ther con.ition.the same steel can.be v.ry hard an. stron.. This v.rsatility is made possible by the differen. heat treatmen.s that the steel can.be subject to. On. such treatmen. is Gas carburizin.. This is the most widely used process for surface harden.n. of low carbon.steels. In.this method the surface composition.of the steel chan.es by diffusion.of carbon.an. or n.trogen.an. result in.hard outer surface with good wear resistan.e properties. A strikin. feature of Gas Carburizin. process is that in.this process the origin.l toughn.ss an. ductility remain. un.ffected ev.n.after heat treatmen.. 3% n.ckel chromium case harden.d low carbon.steels are widely used for critical automotiv. an. machin. application. such as rack an. pin.on. gears, camshaft, v.lv. rocker shafts an. axles which requires high fatigue resistan.e. Fatigue behav.our of case carburized parts depen.s to a great exten. on.the correct combin.tion.of Hardn.ss Pen.tration.Depth (HPD) an. the magn.tude of hardn.ss at the surface an. ben.ath the surface with low size an. shape distortion. In.order to reduce the man.facturin. costs in.terms of material con.umption.an. elimin.tion.of the n.mber of processin. steps, the effect of Gas carburizin. parameters on.the fatigue behav.our should already be con.idered in.the parameter design.stage. Therefore it is of importan.e to optimize the gas carburizin. process v.riables to attain.quality products with respect to hardn.ss an. case depth. In.the presen. paper, the ev.luation.of process capability was carried out through a Limit Design.Con.ept called orthogon.l array design.of experimen..

The set describes tran.mission.of gas through a compressor shop as a fluid dyn.mics model with lumped parameters. The proposed method is orien.ed to wide application.by specialists workin. in.the gas in.ustry. The practical application.of this method can.use all-purpose programmin. an. mathematical software av.ilable to specialists of gas compan.es.

The structure an. the magn.tic properties of rf-sputtered n.uoscale Tb in.[Tb/Ti]n.an. [Tb/Si] multilayers hav. been.studied experimen.ally.

The observ.d displacemen. of a magn.tic orderin. temperature to the lower temperature ran.e an. the shift of magn.tic hysteresis obtain.d in.the ZFC-FC terms may be caused by the size effect an. the amorphization. Both the first an. the secon. suppress the exchan.e in.eraction.an. decrease the crystallin. magn.tic an.sotropy.
