基于免疫抗体生成算法的电力变压器故障诊断

提出了一种基于人工免疫的抗体生成算法,并将其应用于电力变压器的故障诊断。抗体生成算法仿生生物免疫系统中抗体对抗原的识别与记忆的机理,先对训练样本进行免疫学习和记忆,提取表征样本的有效特征,形成表征样本特征的记忆抗体集,再用最邻近分类法对测试样本进行分类识别。UCI的Iris数据集和电力变压器故障数据的仿真分析结果表明,抗体生成算法能够进行有效的分类,并具有很高的准确率。     

Synthesis and photoconductivity study of phthalocyanine polymers. I. PAA–CuPc(NO2)2

Cu–dinitro–diamino phthalocyanine was synthesized and converted to the diazonium salt. Polyacrylamide bonded CuPc(NO₂)₂ [PAA–CuPc(NO₂)₂] (I) was synthesized by hot polymerization of acrylamide and this diazonium salt. Polymer(I) is water soluble and contains about 7 mol % CuPc(NO₂)₂ rings, which are covalently bonded to PAA. Polymer(I) shows good photoconductivity, which is much better than that of the corresponding phthalocyanine monomers. By doping with iodine (I₂), the photosensitivity of polymer(I) is increased, which through fluorescence analysis is explained by the fact that a charge–transfer complex (CTC) of polymer(I) with I₂ is formed. The influence of interface layer (IFL) and charge–transportation material (CTM) on the photoconductivity of polymer(I) were also studied.     

延长生焦时间对延迟焦化装置的影响

国内焦化装置的生焦时间几乎都采用24小时，设计的焦炭塔空高较大，在装置低负荷生产时，适当延长生焦时间，不仅可降低装置的运营成本、提高焦炭质量、降低劳动强度，而且还可降低维修费用。安庆焦化成功地在一套装置上实现了48小时生焦操作，年运行200天，增效约100万元。

Interaction of Silver/Palladium Electrodes with Lead-and Bismuth-Based Electroceramics

In this study the phase relations between Pd or 70Ag/30Pd electrode systems with commercially important Bi-or Pb-based oxides were determined to establish the conditions under which detrimental interfacial chemical reactions may occur. For the reaction of Pd with Bi compounds, PdBi₂O₄ formation was observed if the reaction proceeded at temperatures less than 835°C. At higher temperatures a Pd (Bi) alloy formed containing the maximum solubility of the Bi, i.e., 16 at.%. For the reaction of Pd with Pb compounds, a Pd (Pb) alloy formed which in all instances exhibited the maximum solubility of the Pb, i.e., 14 at.%. These reactions had an adverse effect on the local stoichiometry and composition of the dielectric, causing depletion of Bi or Pb. Studies on commercial capacitor dielectrics from DuPont (X7R and Z5U formulations) and Pb (Mg_1/3Nb_2/3)O₃ showed that the use of Pd electrodes decreased the dielectric constant substantially, which was due to the formation of a low permittivity phase in series connectivity with the unaltered dielectric.
