:1672-7207(2015)05-1838-07 Relationship between structure and strength property of unsaturated loess ZHANG Ningning, LUO Yasheng (College of Water Resources and Architectural Engineering, Northwest.... The results indicate that the structure of loess is mainly affected by confining pressure and moisture content. The relationship curves between structural strength potential parameter and confining......
. XRD and TEM demonstrate that a three-stage transformation occurs. The Ti3Ni4 precipitates are coherent with the R-phase. The crystal structure of R-phase was analyzed by two diffraction patterns method... and lower sensitivity to structure modifications, hence resulting in higher reversibility and stability. The small hysteresis implies high response rate and high reversibility. Owing to these unique......
of X-ray diffraction analysis show that the crystalline structure of the obtained SiC whiskers is β-SiC. It is considered that the SiC whiskers grow via a vapor-solid mechanism.关键词:......
. The partial substitution of Mn by Ni2+ leads to a decrease in cell volume as well as a structural transition from the rhombohedral to the orthorhombic structure. Ni2+ doping increases the electrical......
phase of Co with about 8 nm in size,exhibiting independent two-phase structure without alloying. Compared to that of single-phase SmCo5 particles, the saturation magnetization of SmCo5/Co nanocomposites......
A Study of the Magnetic Properties of Intermetallic Compound RFe12-xMx黄智全,何文望摘 要:<正> The structure and intrinsic magnetic properties of RFeM(M=V or Ti),type 1:12,have been studied bymagnetic measurement and X-ray diffraction.They are body-centered tetragonal ThMn12structure.Thechanges of crystal lattice constants coincide......
doped with strontium are most advan-tageous for the application.The crystallography,defect structure,conductivity and thermal matching withthe electrolyte and high temperature stability of cathode......
were studied. The heat-treatment temperature is 200 700℃. The as-cast structure of the alloy is typically amorphous. Different melt-spun speed and different heat treatment could result in different......
diffraction (XRD), galvanostatic charge-discharge test, and electrochemical impedance spectroscopy (EIS). The result shows that the structure and electrochemical performance of LiLa0.01Mn1.99O4......
substituted with Sm, the RE-TM alloy film possess large perpendicular anisotropy. The substitution effects on saturation magnetization can be explained with the ferri-magnetical structure of RE-TM alloy film......
