Two 10 kV WTR-XLPE power cables were made of WTR-XLPE insulating material developed by us and have gone through the accelerating aging test of water for 360 days in Wuhan High Voltage Academe in term of power industry standard.It is shown by test results that the resistance ability of the WTR-XLPE to water tree reache…
CdS cores were successfully synthesized in noncoordinating solvents.The composite structure of core/shell CdS ∶ Cu/CdS nanocrystals was obtained through the modification of as-prepared Cu2+ ions doped CdS cores using successive ion layer adsorption and reaction(SILAR) technique.The crystal structures,shapes and optica…
The terbium(Ⅲ) complex and a new Schiff base ligand by 2-acetylbenzimidazole and taurine have been synthesized in methyl alcohol solution.Their structures and properties are confirmed by element analysis,mass spectrometry,IR spectra,1HNMR spectra,three-dimensional fluorescence excitationand emission spectra.The result…
The rapidly solidified alloys strip s with Al-12.6Si were prepared by single roller melt-spinning method.The microstructures,phase and morphology characteristics of the strips were characterized by means of SEM,TEM and DSC technique.The results show that the grains refine after rapid solidification,and the micro-nanoc…
The effects of interval of enhancive voltage on micro-arc oxidation(MAO)coating of magnesium alloy AZ91D were investigated in silicate electrolyte.The microstructures were studied with TT230 digital coating thickness gauge,JSM-6700F scanning electron microscope,2206 surface roughness measuring instrument and W-92 Coat…
A kind of solution is adopted to modify the PPX-C film. The effect of the different concentration and reaction time is studied. The modified PPX-C surface is characterized with X-ray fluorescence spectroscopy(XRF),X-ray diffractomer(XRD) and scanning electron microscopy(SEM). The result of test shows 1.5mol/L and 10 m…
Tiling-grating is one of the important ways widely used to solve the limited size of grating.Tiling-gratings could be N×M times larger than traditional gratings,nevertheless,introduce wave-front distortion,which impacts the spatial and time characteristics of focal beams.The variation of focal spot was simulated by us…
LiV3O8 cathode nanomaterials were synthesized by a hydrothermal route at different reaction temperatures.The structures,morphologies and proprieties of the samples were investigated by XRD,TEM,galvanostatic charge-discharge,cyclic voltammetry(CV),and electrochemical impedance spectroscopy(EIS) techniques.With increase…
Pt-Sn/A2O3 catalysts with different loadings of Sn were prepared by sol-gel and impregnation method and characterized by TEM, H2-adsorption and XPS. Properties of the catalysts for dehydrogena-tion of propane were investigated under severe condition, i. e. , high temperature (550?) and in the absence of H2. It was fou…
Complex of indium chloride tetrahydrate with Schiff base derived from o-vanillin and 1-naphthylamine has been synthesized and characterized by 1H-NMR spectroscopy,infrared spectrometry,X-ray powder diffraction and element analysis.
In order to control the polarization effects of the reflective rotationally symmetric optical systems,polarization aberrations of this type of systems are analyzed.The expressions of the polarization aberrations are deduced by the method of polarization ray tracing based on polarization aberrations theory.The influenc…
Pulsed corona discharge plasma was used to treat ethanethiol in the air.The influences of gas flow rate(or residence time) and moisture of gas flow on removal efficiency were investigated.As a result,the removal efficiency decreased obviously with increasing gas flow rate,because both the residence time of ethanethiol…
NaX-molecular sieve was used as carrier and was dipped into Ce3+ solution by impregnation.The removal effect of thiophene from gasoline using modified molecular sieve was tested which including the effect of its dosage,adsorption time,initial concentration and mixing speed.The adsorption,before and after the modificat…
The bonding strength between membrane and matrix is an important index to evaluate the film quality.The type of ceramic coating generated by plasma electrolytic oxidation has good bonding strength.However,a large number of studies on the combination mechanism of film did not conduct further research.The phase structur…
The purpose of reactor physics tests is to demonstrate the validity of reactor core design and refueling safety analysis report.Physics test points for some NPPs in China are fewer,which leads to insufficiency of above demonstration and increases the uncertainty of next fuel cycle design.Moreover,it will lead to that…
Poly(n-alkyl acrylates) with alkyl carbon number 14,16,and 18 and different molar mass were synthesized and notated as PA-14,PA-16,and PA-18.By using DSC technique and a straight-run diesel as solvent,the solution crystalization characteristics of these polyacrylates,their effects on the solution crystalization charac…
By using grey theory,the influences of chemical composition and microhardness on wear resistance rate of wear resistant white cast iron were anlyzed,and the influences and their sequences of the chemical composition and microhardness of both the metal matrix(HV 1 )and the carbide(HV 2 )were calculated.The calculation…
