In order to take data information from the slag property diagram in a ternarysystem automatically and actually, a picture recognition and drawing software has been developed byVisual Basic 6.0 based on the image coding principle of computer system and the graphicsprogramming method of VB. This software can transform the ternary system isopleth diagram frombitmap format to data file and establish a corresponding database which can be applied to rapidlyretrieve a mass of data and make correlative thermodynamics or kinetics calculation. Besides, itstill has the function of drawing the ternary system diagram which can draw different kinds ofproperty parameters in the same diagram. 展开更多

The potential—pH diagrams of the Cr-H2O system at temperatures of 298, 323, 373 and 423 K were established through thermodynamic calculation with coupling of experimental results. The potential—pH diagram at 298 K agrees well with the previously reported results. Based on the potential—pH diagrams of the Cr-H2O and Fe-H2O systems, IR spectra and XRD pattern, the existence forms of iron in the potassium chromate were analyzed, and the methods of iron removal were investigated. The results show that the existence forms of iron in the potassium chromate are potassium ferrate. These results are instructive and helpful to the hydrometallurgical processing of chromite ore. 展开更多

On the basis of Au-Ag, Au-Dy and Ag-Dy binary phase diagrams, the 700℃ isothermal section of Au-Ag-Dy ternary system(Dy≤35%, mole fraction) was established by X-ray diffraction analysis, differential thermal analysis and optical microscopy. It is found that there is a long single-phase region, Au(Ag) or Ag(Au), along the Au-Ag binary isomorphous system on the gold-silver-rich side of the 700℃ isothermal section and between the binary compound Au2Dy and Ag2Dy there is the all proportional solid solution, (Au2Dy) or (Ag2Dy). It is confirmed that the partial 700℃ isothermal section consists of six single-phase regions: solid solution Au(Ag) or Ag(Au), (Au2Dy) or (Ag2Dy), Au6Dy, Au51Dy14, Au3Dy and Ag51Dy14; nine binary-phase regions: (Au2Dy)+Au(Ag), Au6Dy+Au(Ag), Au(Ag)+Ag51Dy14, Ag51Dy14+(Au2Dy), Au3Dy+(Au2Dy), Au3Dy+Au51Dy14, Au51Dy14+Au6Dy, Au51Dy14+Au(Ag) and Au(Ag)+Au3Dy;four ternary regions: Ag51Dy14+(Au2Dy)+Au(Ag), (Au2Dy)+Au(Ag)+Au3Dy, Au(Ag)+Au3Dy+Au51Dy14 and Au51Dy14+Au(Ag)+Au6Dy. No new ternary compound is formed in the gold-silver-rich field(Dy≤35%) of the Au-Ag-Dy ternary system. 展开更多

The phase diagrams and phase transitions of a typical bilayer fractional quantum Hall (QH) system with filling factor ν = 2/3 at the layer balanced point are investigated theoretically by finite size exact-diagonalization calculations and an exactly solvable model. We find some basic features essentially different from the bilayer integer QH systems at ν = 2, reflecting the special characteristics of the fractional QH systems. The degeneracy of the ground states occurs depending on the difference between intralayer and interlayer Coulomb energies, when interlayer tunneling energy (ΔSAS) gets close to zero. The continuous transitions of the finite size systems between the spin-polarized and spin-unpolarized phases are determined by the competition between the Zeeman energy (ΔZ) and the electron Coulomb energy, and are almost not affected by ΔSAS. 展开更多

A criterion of the metastable extension of solid solubility was proposed.When the eutectic concentration arm ratio parameter of an alloy,J>10,the hypereutectic extension and the metastable solid solubility limit beyond eutectic concentration may be obtained.When J≤10, the hypoeutectic extension may be obtained.The extension parameter,C_(eq)~s/C_(cu),is directly proportional to the parameter J.Thus,it seems easy to predict the tendency of the solid solu- hility extension under rapid solidification on the basis of the eutectic phase diagram. 展开更多
