Based on the previous experiments, we choose CNTs/CdS core-shell nanowires as inorganic materials and poly(benzyl-ether) dendrons with thiol functionalities as organic solubilizer. The solubility of CNTs/CdS core-shell nanowires in normal solvents was expected to improve through chemical interactions between core-shell nanowires and solubilizer. The enhanced solubility can improve facility in processability. It also provides a new application method in nanomaterials.

本论文在课题组原有工作的基础上，以制备可溶、易加工的有机-无机复合纳米材料为应用目标，选择具有自己课题组研究特色的CNTs/CdS核壳纳米线结构作为无机材料，选择带巯基的聚苯甲醚树枝状分子作为有机增溶剂，通过带巯基的聚苯甲醚树枝状分子对CNTs/CdS核壳纳米线的化学作用，改善了核壳纳米线在常用有机溶剂中的溶解性能，为材料的湿法加工提供了基础，也为类似纳米材料的应用开拓了一种新的方法。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
