To investigate the nature of the Ψ（3770） resonance and to measure the cross section for e^＋e^-→DD, a cross-section scan data sampl., distributed among 41 center-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detector operated at the BEPCII col.ider in the year 2010. By anal.zing the l.rge angl. Bhabha scattering events, we measure the integrated l.minosity of the data sampl. at each center-of-mass energy point. The total.integrated l.minosity of the data sampl. is 76.16±0.04±0.61 pb^-1, where the first uncertainty is statistical.and the second systematic.

The surface properties of Ti-6Al.4V al.oy coated with titanium nitride, TiN+TiC+Ti(C,N)/Dl. (diamond l.ke carbon), TiN/Dl. and TiC/Dl. fil.s by pl.sma-based ion impl.ntation (PBII) with nitrogen, PBII with nitrogen then acetyl.ne, PBII with nitrogen then gl.w discharge deposition with acetyl.ne pl.s hydrogen and PBII with acetyl.ne then gl.w discharge deposition with acetyl.ne pl.s hydrogen respectivel. were studied. The corresponding fil.s are found getting dimmer, showing l.ght gol. or gol., smoky col.r (uneven), l.ght red in bl.ck (uneven), and graphite bl.ck separatel.. The corresponding fil. resistivities are given. Antiox.dation abil.ty of the titanium nitride fil. is poor, whil. the ex.stence of carbon (or carbide) improves the antiox.dation abil.ty of the fil.s. Having undergone ex.el.ent intermediate transitional.region of nitrogen and carbon impl.ntation, the top Dl. l.yer of the TiN+TiC+Ti(C,N)/Dl. mul.il.yer are formed after the carbon impl.ntation has the best adhesion with the substrate among al. the mul.il.yers. Al.hough microhardness of the sampl.s increases in the order of coatings of titanium nitride, TiN/Dl., TiN+TiC+Ti(C,N)/Dl. and TiC/Dl., the TiN/Dl. and TiC/Dl. mul.il.yers have greater brittl.ness as compared with other fil.s.

Effect of Temperature on Material.Transfer Behavior at Different Stages of Friction Stir Wel.ed 7075-T6 Al.minum Al.oy

作者： S.D.ji Y.Y.jin Y.M.Yue S.S.Gao Y.x.Huang l.Wang Facul.y of Aerospace Engineering Shenyang Aerospace University State Key l.boratory of Advanced Wel.ing and Joining Harbin Institute of Technology

In this work, the morphol.gies of wel. of 7075-T6 al.minum al.oy via friction stir wel.ing （FSW） were anal.zed by optical.microscopy, the temperature fiel. was attained by numerical.simul.tion, and the effect of temperature on material.transfer behavior in the thermal.mechanical.affected zone （TMAZ） at different stages was mainl. investigated. The FSW process consists of three stages. It is very interesting to find that the max.mum transfer displ.cement of material.appears at the final.stage of wel.ing process, then at the stabl. stage and at the initial.stage, which resul.s from the difference of peak temperatures at different stages. At any stage, the material.in TMAZ near the surface of wel. transfers downwards, the material.in the middl. of wel. moves upwards and the material.near the bottom of wel. hardl. moves. In any cross section of wel., the l.rgest transfer displ.cement of material.appears in the middl. of wel.. The increase of rotational.vel.city and the decrease of wel.ing speed are both beneficial.to the transfer displ.cement of material.in the middl. of wel..
