基于电热场平衡锂电解强化研究

利用有限元法建立了三维锂电解槽电热场仿真模型,考察了电解槽结构参数对电热场的影响。结果表明,缩短阴阳极间距(ACD),增加阳极半径(Ar)、阴极厚度(Ct)及阴极高度(Ch)均可以在保持能量平衡的前提下提高电解槽的电流强度。对上述参数进行无量纲化研究,得到了方程:CI=30000×(ACD/40)~(-0.24519)×(Ar/150)~(0.79291)×(Ct/225)~(0.09835)×(Ch/700)~(0.37953),对于电解槽的放大设计,可以根据上述方程,不对电解槽进行复杂的建模计算,进而节省资源,提高效率。

Electroplating and characterization of Zn-Ni, Zn-Co and Zn-Ni-Co alloys

Zn-Ni, Zn-Co and Zn-Ni-Co coatings were electrodeposited on mild steel from an acidic chloride bath containing p-aminobenzenesulphonic acid (SA) and gelatin. These additives changed the phase content in the coatings, most likely as a result of their adsorption at the surface of the cathode. The effect of gelatin was more pronounced than that of SA. The Faradaic efficiency was higher than 90%. As the current density was increased or the bath temperature was decreased, the concentration of the nobler metal in the coating increased. Both concentrations of Ni and Co in the ternary alloy increased as the applied current density was increased. Nickel and cobalt were found to have a synergistic catalytic effect. The thickness of all coatings increased as the applied current density was increased. The hardness increased with current density to a peak value, and then decreased. The rate of Zn deposition was heavily influenced by mass-transport limitation at high applied current densities, while the rates of Ni and Co deposition were not. The anomalous codeposition was explained by the great difference between the exchange current densities of Zn and the iron-group metal. Potentiodynamic polarization scans and electrochemical impedance spectroscopy showed that the corrosion resistance of the ternary Zn-Ni-Co alloy coatings was approximately 10 times higher than that of Zn-Ni and 7 times higher than that of Zn-Co. The improved corrosion resistance of the ternary alloy was attributed to its surface chemistry, phase content, texture, and surface morphology. The ternary Zn-Ni-Co coating may thus replace the conventional Zn-Ni and Zn-Co coatings in a variety of applications.

Financial econometric analysis at ultra-high frequency: Data handling concerns

Data collection at ultra high-frequency on financial markets requires the manipulation of complex databases, and possibly the correction of errors present in the data. The New York Stock Exchange is chosen to provide evidence of problems affecting ultra high-frequency data sets. Standard filters can be applied to remove bad records from the trades and quotes data. A method for outlier detection is proposed to remove data which do not correspond to plausible market activity. Several methods of aggregation of the data are suggested, according to which corresponding time series of interest for econometric analysis can be constructed. As an example of the relevance of the procedure, the autoregressive conditional duration model is estimated on price durations. Failure to purge the data from “wrong” ticks is likely to shorten the financial durations between substantial price movements and to alter the autocorrelation profile of the series. The estimated coefficients and overall model diagnostics are considerably altered in the absence of appropriate steps in data cleaning. Overall the difference in the coefficients is bigger between the dirty series and the clean series than among series filtered with different algorithms.
