The thermal conductivity of the polymer can be improved by adding boron nitride and multi walled carbon nanotubes .When the loading of BN was 50wt%, the thermal conductivity rate of ultra high mole-cular weight polyethylene reaches from 0.456W/ (M·K) to 0.9157W/ (M·K); when adding 1wt% MWCNT, the thermal conductivity coefficient of the composite further increased to 1.370W/ (M·K), more than 33% compared with single filler. It is showed that there was a significant synergistic effect between BN and MWCNT filler, which can form a good conductive pathway in the material. Scanning electron microscopy (SEM) analysis showed that the MWCNT effectively improved the interfacial bonding strength between BN fillers. Thermal gravimetric (TGA) analysis showed that the thermal stability of UHMWPE was significantly improved by adding MWCNT. Depth Digital Optical Microscopy (DDOM) confirmed that the composites formed segregated structure of “filler -polymer interface” and conductive pathways effective formation.

In the retrieval of CAD 3D model, the distance of the output results for the classifier and the distance for the feature space were weighted to calculate, which not only considered the difference of between the model's content and features, at the same time, and appended classification information parameters, but also took into account the semantic classified information of model. The experimental results showed that the classification method based on neural network ensemble could effectively improve the classification accuracy of CAD 3D model as well as consider the distance between models in feature space and the distance between models at semantic classification level, so that the 3D CAD model retrieval could be greatly improved accuracy.
