1VOLUMETRIC MASS TRANSFER COEFFICIENT BETWEEN SLAG AND METAL IN COMBINED BLOWING CONVERTER显示文摘The effects of operation parameters of combined blowing converter on the volumetric mass transfer coefficient between slag and steel are studied with a cold model with water simulating steel, oil simulating slag and benzoic acid as the transferred substance between water and oil. The results show that, with lance level of 2.1m and the top blowing rate of 25000Nm3/h, the volumetric mass transfer coefficient changes most significantly when the bottom blowing rate ranges from 384 to 540Nm3/h. The volumetric mass transfer coefficient reaches its maximum when the lance level is 2.1m, the top blowing rates is 30000Nm3/h, and the bottom blowing rate is 384Nm3/h with tuyeres located symmetrically at 0.66D of the converter bottom.Z.H.Wu Z.S.Zou W.Wu 2005Acta Metallurgica Sinica(English Letters)2005,18,2:3

3MICROSTRUCTURAL CHARACTERIZATION OF SPIN—VALVE MULTILAYERS BY X—RAY ANOMALYOUS DIFFRACTION TECHNIQUE显示文摘It is impossible to directly analyze the microstructure of spin-valve multilayers based on Ni,F,Cu and Mn by a conventional X-ray diffraction technique because the lattice parameter and atomic sattering factor sof them are very close.To solve this problem, we use an x-ray anomalous diffraction technique to characterize the microstructures of the [Ni80Fe20/Fe50Mn50]15 and [Ni80Fe20/Cu]15 superlattice systems.The results show that more diffraction peaks and higher internsity in the reflectivety profile are observed when the incident energy is close to the absorption edge of the lighter element(Mn) in [Ni80Fe20/Fe50Mn50]15 multilayer systems and to the absorption edge of the heavier element (Cu) in the [Ni80Fe20/Cu]15 multilayer systems.The interface and periodic structure of [Ni80F20/Fe50Mn50]15 are more perfect than that of the [Ni80Fe20/Cu]15 superlattices.The above results are disussed in this paper.M.XU G.M.LUO T.YANG C.C.CHAI Z.H.MAI W.Y.LAI H.Y.JIANG Z.H.WU 2001Beijing Synchrotron Radiation Facility2001,,2:0
4Research of nonlinear optical properties of copper nanoparticles显示文摘This research reports the preparation and characterization of copper nanoparticles modified by didecyl benzene sulfonate (DBS),The Cu nanoparticles' size was determined to be 40nm by transmission electron microscope(TEM).The X-ray photoelectron spectrometry(XPS) results show that there are interactions between the copper nanoparticles and DBS function group.The nonlinear optical properties were studied by the four-wave mixing method.The value of x^(3)/α0 was found to be 6.9×10^-11 esucm.L.Guo Z.H.Wu1999同步辐射装置用户科技论文集1999,,1:0
