The high speed electrogalvanizing process was optimized and the effects of technological parameters on the performances of coating,including black patina resistance,micro-morphology and degree of orientation of crystal face,were investigated by SEM and XRD analyses in dynamic state respectively.The best process condit…
Ag-CuO sealing material was used to realize the sealing between the SUS430 interconnect and the NiO-YSZ anode in air.Leakage rate were tested,and SEM and EPMA tests were conducted to determine its hermeticity,compatability and thermal cycling stability.Results indicated that Ag-CuO sealing material could realize the s…
The problems of the integral tooth-roller,such as shrinkage,porosity shrinkage were solved because the roll body was casted alone to avoid the hot spot.And upper and lower roller used the dense forging.These make whole performance greatly improved.Meanwhile,interior tubular structure was used to ensure a uniform cooli…
uperelastic shape memory alloy(SMA) X type plate damper has energy dissipation and re-centering capa-bilities.The damper's piecewise linear hysteretic model is set up,and the dynamic response analysis of a single degree of freedom structure with the SMA damper subjected to earthquakes is put forward.Numerical simulati…
The effect of submerge entry nozzles(SEN) with three types of outlets including normal single straight,quad-furcated in radial direction and quad-furcated at tangential on the flow patterns,solidification behavior of molten steel in bloom casting mold were investigated by numerical computing method.With present normal…
The basic situation of Northwest Disposal Site is introduced.The organization and management system,disposal technology,radiation protection,environmental monitoring of low-and medium-level radioactive solid waste recept and disposal in Northwest Disposal Site are also presented.It provides reference and support for o…
Objective To develop cisplatin-loaded long-circulating liposomes modified with transferrin(Tf-PEG-CDDP).Methods The blank liposomes were prepared by thin film dispersion-ultrasound method and cisplatin was packaged by ammonium sulfate gradient method.Tf-PEG-CDDP was prepared by binding transferrin to maleimide termina…
Simulation test of rolling and continuous annealing of a C-Mn-Si TRIP steel was carried out on a Gleeble-3500 thermal simulation tester.The effect of the process on microstructure and mechanical properties of the cold rolled TRIP steel was examined.The process was mainly characterized by coiling at lower temperature a…
By imitating the process of using polyester DTY in the weaving factory,creating a simple test equipment and making test code,the unwinding performance test of polyester DTY is carried out.It is to verify that when the materials,technology,equipment and other processing conditions change,the unwinding of the product pe…
Folic acid receptor(FR) was usually overexpressed in many cancer cells and was considered as potential target for targeted therapy agent.We decorated dendrimer polyamidoamine generation five-folic with acid and 1B4M-DTPA and then radiolabeled with ~(188)Re.Thes in vitro stability was evaluated.The labeling yield of th…
An ITO/NPB/PAA/Alq3:DCJTB/Alq3/Mg:Ag white organic light-emitting device based on PAA was fabricated.An excellent white light emission was achieved by mixing the blue light and the yellow light from PAA layer and Alq3:DCJTB layer,respectively.The turn-on voltage of the device is 4.6 V,the maximum luminance efficiency…
Due to the problem of unfitness of business wear and the design requirement of an emterprise,pattern design and ease design are analyzed.A new pattern design of jacket business wear based on human characteristics is put forward,the exact ease and relevant parts freedom of jactet business wear are determined by wearing…
Polybutylene terephthalate(PBT)was irradiated by electron accelerator.The influences of absorbed dose,crosslinking agent content and radiation atmosphere on gel content of PBT were investigated.The effects of radiation crosslink on the mechanical properties and crystal behavior of PBT were studied.The results indicate…
Transparent and conductive c-axis oriented aluminum-doped zinc oxide(AZO) films have been prepared on glass substrate by DC magnetron sputtering processing.For this purpose,a sintered ceramic disc of ZnO mixed with Al2O3 is used as the target.The microstructure of AZO ceramic target is characterized by micro-Raman spe…
Corrosion behaviors of Mg-4Zn-Y-xSb(x=0,0.5,1,2)alloys in the 3.5% NaCl solution were investigated,and effects of Sb addition on corrosion resistance of Mg-4Zn-Y alloys were also studied by optical morphology,electrochemical polarization curves and electrochemical impendence spectrum(EIS).The results show that the add…
