        摘要：The main present technologies producing self-reinforced polymers by means of injection molding is summarized. The technologies producing uniaxially self-reinforced polymers(such as high-pressure injection molding, elogational flow injection molding and shear controlled injection molding) and those producing biaxially self-reinforced polymers (such as injection-compression molding , rotational injection molding, oscillation injection molding and shear controlled injection molding ) are introduced.

        摘要：In this report, we simply introduce the macromolecular simulation theories and a precise simulation method-VEH method. The calculation result such as energy structure, frontier orbital energy level, energy bond and transition energy etc are correlated with the experimental determination such as conductivity, redox potential, UPS spectra, UV/VIS absorption and emission spectra photo-and thermo-stability, which are related to the properties of organic LEDs materials. The design method of new organic LEDs materials aided by molecular simulation is given and discussed.
