In order to increase antibacterial abilities and avoid the aggregation of nanoparticle, Ag- ZnO nanocomposites were studied in the network structure which contains bonds, and these bonds are formed by hydrolysis reaction between Ti（TBOU）4（TBOT） and the water that in Persimmon tannin solution. The size and morphology of Ag-ZnO nanocompos：tes were investigated by scanning electron microscopy （SEM） and field emission scanning electron microscopy（FE-SEM）. The antibacterial properties of nanocomposites were examined by minimal bactericidal concentration（MBC）. Results showed that this kind of antibacterial nanocomposites composites（ANPs） have excellent antibacterial abilities and without aggregation.

Performance management has become a competitive advantage of enterprises to cultivate core competitiveness of strategic initiatives, but how to act performance management out scientifically has been difficult. An unclear understanding of the various issues often results in improper handling counterproductive. Thus, we should analyze human resource performance management problems and their causes, and only on this basis can we establish and implement effective hunlan resource management system dynamic performance during the difficulties and the main factors that should be considered to elaborate.

有效地诊断出特高压直流输电(UHVDC)系统中的换相失败故障,对故障后采取适当的控制措施以及避免交流系统保护装置的误动作具有重要意义。在云广±800 k V UHVDC系统中,对不同故障条件下的直流线路短路故障和换相失败故障进行仿真,利用改进的形态滤波器对不同故障条件下电流的线模分量进行6尺度分解,并提取各尺度下的形态谱。结合形态能谱熵和奇异谱熵提取故障特征,定义两个故障诊断指标作为判别系统运行状态的判据,然后针对这两个指标分别设置4个阈值HE0、HE1、HS0、HS1来诊断直流系统运行状态,即正常运行、线路短路故障、换相失败故障。对不同故障条件下的线路接地短路故障和换相失败故障进行大量仿真,仿真结果表明,该方法能准确地诊断出线路接地短路和换相失败故障。
