Curing kinetics of epoxy resin and the effects of different compositions on curing reaction were researched by using the differential scanning calorimeters. Relationship between curing temperature and curing converting rate had been studied. Curing conditions for the system were determined. Modified nano-Al2O3/epoxy resin and core shell/epoxy resin composites were prepared by means of blending method. The influence of the composition on the properties was discussed. The thermal and dielectric properties of these composites were investigated using differential scanning calorimetry, Thermogravimetry and dielectric analyzer.

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.
