The KF-NaF-AlF3-based electrolyte is a kind of promising bath in low-temperature aluminium reduction,in this paper,the physical-chemical properties of this system are reviewed,including the published research results of liquidus temperature,conductivity and alumina solubility in recent years.

The changes of crude protein content and the hydroxide potassium solubility of mildewed soybean meals were studied through two kinds of soybean meals(12.

This article mostly analyzed salt fog test conditions, validating infection oftemperature,oxygen solubility,salinity,velocity of flow for salt fog by testing ,and researchedthe technique of putting samples on the bracket.

) The periodic variation of the concentration of Fe~(3+) on galena surface driven by dissolved oxygen in an open system,the formation of sulfur and its further oxidative dissolution on the galena electrode surface,and the re.

Al2O3 ceramic coatings were prepared on mild steel substrates with alumina sol as precursor by electrophoretic deposition and low-temperature sintering.

In order to reduce the ratio of the anode oxidation and excessive anode consumption,the writer puts forward a method that the relatively compact alumina coatings(film),alumina sol as the basic cohere component, is prepared on carbon anode surface by original located solidification.

Based on the infrared anomalous dispersion of compact alumina film, the character of alumina sols and the processing for fabricating compact alumina film were studied by using sol-gel method.

Based on the analysis of gas-liquid mass transfer and liquid flow in the reactor of bioartificial liver support system, and comprehensive consideration of the configuration and the actual needs of the reactor, the mathematic mechanism model of dynamic distribution of dissolved oxygen concentrations in the reactor was build up based on one-dimensional axial diffusion model.
