碳纳米管增强型复合材料功能梯度板的自由振动模型与尺度效应

基于一种新的各向异性修正偶应力理论，建立了碳纳米管增强复合材料功能梯度板的自由振动模型。该模型能够描述尺度效应，且仅包含一个尺度参数。基于一阶剪切变形理论和哈密顿原理推演了板的运动微分方程，并以四边简支板为例给出了自振频率的解析解。讨论了板的几何尺寸、碳纳米管体分比含量和分布方式等因素对板的自振频率的影响。结果表明，本文模型所预测的板的自振基频总是高于经典弹性理论的Mindlin板模型的预测结果，两者间的差异在板的几何尺寸接近尺度参数的值时非常明显，且会随着板的几何尺寸的增大而逐渐消失。     

复合电极La-Ni-B的制备及电催化偏硼酸钠的性能

为进一步提高对偏硼酸钠电催化还原的效率,采用化学镀的方法,以铜片为基体,PdCl2乙醇胶体溶液为活化剂,乙醇为化学镀溶剂,制备了稀土复合电极La-Ni-B.并采用XRD、SEM、EDS方法对催化剂进行表征分析,结果表明稀土合金以纳米颗粒的形式附着在基体表面,所得合金膜是非晶态的.通过循环伏安法研究了复合电极La-Ni-B用于电解偏硼酸钠制备硼氢化钠的可行性.以硼氢化钠实际生产量为指标,探讨了直流、脉冲两种不同供电方式、脉冲电流频率、电解时间对电解行为的影响.结果表明稀土镧对电解偏硼酸钠有催化作用,以20 mL镀液制备的复合电极,在脉冲频率阳极时间T1=1 s,阴极时间T2=1 s时,最佳电解时间为4h.复合电极在重复使用3次的情况下,硼氢化钠产量降低15;,催化剂的重复使用性能良好.
