The electrochemical performance of the carbon cloth(CC)-based flexible electrodes is determined by the kind,micro-structure, and morphology of the deposited pseudocapacitive materials. In the present work, the coral-/urchin-like polyaniline(PANI) was designed to boost the electrochemical property of CC, by integrating the microstructure advantages of coral-like and nanowire arrays, via the facile electrochemical polymerization of aniline on the functionalized carbon cloth(FCC) in salty media. The corresponding electrode delivered a high specific capacitance of 3376 m F cm-2at 1 m A cm-2and 151 F g-1at 1 A g-1, with an ultrahigh boosting in specific capacitance of 246 % and superior cycling stability of 149.8 % after 10,000 cycles, in comparison with the reported PANI/CC ones via electrodeposition. This work provided a new idea for the construction of conductive polymers with unique nano-architectures on CC for high-performance electrodes for flexible supercapacitors.

Five negatively charged organic compounds with different structures, sodium methane sulfonate(MS), sodium benzene sulfonate(BS), sodium 6-hydroxynaphthalene-2-sulfonate(NSS), sodium dodecyl sulfate(SDS), and sodium dodecyl benzene sulfonate(SDBS), were used to examine the fouling of an anion exchange membrane(AEM) in electrodialysis(ED),to explore the effect of molecular characteristics on the fouling behavior on the AEM and changes in the surface and electrochemical properties of the AEM. Results indicated that the fouling degree of the AEM by the different organics followed the order:SDBS > SDS > NSS > BS > MS. SDBS and SDS formed a dense fouling layer on the surface of the AEM, which was the main factor in the much more severe membrane fouling, and completely restricted the transmembrane ion migration. The other three organics caused fouling of the AEM by adsorption on the surface and/or accumulation in the interlayer of the AEM, and exhibited almost no influence on the transmembrane ion migration. It was also concluded that the organics with benzene rings caused more severe fouling of the AEM due to the stronger affinity interaction and steric effect between the organics and the AEM compared with organics with aliphatic chains.

提出了一种基于不变集切换的非线性系统鲁棒预测控制算法,采用分段蕴含方法将非线性系统动态用一组线性变参数(LPV)系统动态包裹;计算出非线性系统的平衡面,对于每个LPV蕴含模型,针对相应的平衡点构造多面体不变集,得到覆盖非线性系统平衡面的一组相互重叠的不变集;在线根据系统当前状态所处的不变集和LPV区间切换控制律,最终保证闭环系统的稳定性。与传统的非线性预测控制相比,这种方法在构造不变集和确定控制律的计算都是离线进行,而在线只需根据当前状态切换控制律即可,从而避免了求解复杂的非凸非线性规划,在很大程度上降低了在线计算量。

目的小净距多线隧道在轨道交通工程中应用广泛,但由于施工步骤繁多且掘进过程中影响因素较多,需设计合理的小净距多线隧道并行掘进方案。方法采用2种不同开挖顺序的并行掘进方案,通过建立三维有限元数值仿真模型,比较2种方案的隧道围岩应力与位移发展规律,分析现场监测数据,对比模型的准确性,确定掘进方案的可行性。结果结果表明,开挖顺序对围岩间相互作用影响明显,中隧应力和变形受影响最大。中隧先挖法可以较好地避免应力较为集中现象,2种开挖方式的变形值均在安全范围内;依次开挖法和中隧先挖法拱腰处水平应力的变化规律基本一致,依次开挖法的拱顶处垂直应力比中隧先挖法的大40%左右;中隧先挖法的拱腰水平变形和拱顶沉降值分别比依次开挖法的增大23%,26%,但中隧先挖法开挖初期的沉降值较少;中隧先挖进度较快,应力和沉降控制能力优于依次开挖法,数值模拟方法能较好反映真实施工情况,现场监测结果也表明中隧先挖法适用于小净距隧道进口段施工。结论综合考虑衬砌结构应力、变形和施工工期,现场可采用中隧先挖法进行施工。研究结果可为类似小净距多线并行隧道工程设计与施工提供理论参考。
