In order to understand the effect of thermo hydrogen treatment(THT) on high temperature tensile behavior of a Ti2AlNb based alloy plate, high temperature tensile tests of Ti-22Al-25Nb alloy plates without and with 0.2%H(mass fraction) charging were conducted with strain rate of 2.5×10- 2s- 1at 870, 900, 930 and 990℃ r…
The thermal scratch seriously affects the surface quality of the cold rolled stainless steel strip. Some researchers have carried out qualitative and theoretical studies in this field. However, there is currently a lack of research on effective forecast and control of thermal scratch defects in practical production, e…
Aiming at the characteristics and current status of refineries' odor pollution, the sulfur containing odor gas-hydrogen sulfide was chosen as a typical object and treated by using the adsorption-catalytic oxidation method in the laboratory. This research focused on the preparation of adsorptive catalyst with high sulf…
By using nonequilibrium Monte Carlo simulation approach,the shearing effects on the sol-gel transition of ABA telechelic triblock copolymers in a B block selective solvent were investigated. The simulation results show that the shear makes the sol-gel transition concentration area shifting to lower concentrations. Mic…
Laryngeal carcinoma is poor prognosis and patients with laryngeal carcinoma usually present late leading to the reduced treatment efficacy and high rate of recurrence. Incidence and mortality rates of laryngeal carcinoma are equivalent,suggesting a failure of current therapies,despite the variety of combined modality…
Novel hollow tetragonal starlike polyaniline (HTS-PANI) doped with citric acid has been successfully synthesized by hydrothermal method for the first time. Scanning electron microscopy, transmission electron microscopy, UV-visible spectroscopy, Fourier transmis- sion infrared spectroscopy, and X-ray diffraction were e…
A Dunaliella strain was isolated from Yuncheng Salt Lake,Shanxi,China(111.05°E,35.03°N).Morphological characteristics and molecular data were used to evaluate the relationship of this algal strain to other Dunaliella

The equilibrium geometries,relative stabilities,and electronic properties of Ca2Sin(n=1–11)clusters have been systematically investigated by using the density function theory at the 6-311G(d)level.The optimized geometries indicate that the most stable isomers have three-dimensional structures for n=3–11.The electronic…
Y 阶段，改进了 AZ91 的腐蚀抵抗镁合金。与 AZ91 合金相比， AZ911.5Ca1.0Y 合金的腐蚀率被减少到 16.2% ，并且它的腐蚀电流密度被去在在 3.5 的沉浸以后的一个数量级 ? 24 的 wt% NaCl 答案 ? h。
The influence of sodium carboxy methyl cellulose(CMC) on the curing process of epoxy resin E44 with 4,4′-diamino diphenyl methane(DDM) was studied by using infrared spectra and thermal analytical methods. Infrared spectra indicated that the CMC contributed to forming more polyether structures during the curing process…
Directly quenched Nd9.5Fe81Zr3B6.5 nanocomposite permanent magnets were prepared under different melt treatment conditions, i.e., the melt temperature was varied prior to ejection onto the quenching wheel. The effect of quenching temperature on the microstructure and magnetic properties of the alloys was studied by X-…
The leakage current mechanism of poly(methyl-methacrylate)and poly(vinylidene fluoridetrifluoroethylene)double layer structure insulator film,which was fabricated by spin-coat process on silicon and provided a capacitance approaching 32nF/cm2,was investigated in the paper.The experiment result shows that there are two…
