Green-emitting strontium thiogallate doped with Eu(SrGaS:Eu)thin film phosphors were prepared by the multi- source deposition technique using two electron beam evaporation sources and a thermal annealing at higher than 800℃ or both low temperature annealing and laser annealing using krF excimer laser in atmosphere of 1% HS diluted with Ar. The film annealed at 850℃ showed a luminance of around 2.7×10cd/m under excitation with 5kV and 60μA/cm. Moreover,In this study,preparation of green-emitting SrGaS:Eu thin film phosphors by thermal annealing at tempera- tures lower than 600° was also tried with an assist with a laser annealing technique with 248nm due to krF excimer laser. It was shown that the film annealed at 500℃ consisted of SrGS single phase and showed about 2000cd/m under excita- tion with 4 kV,60μA/*** results indicate that the process of the laser annealing is useful for the realization of FEDs with high performance.

＜正＞In order to obtain the basic knowledge needed for an efficient flat membrane filtration system for the wastewater from chemical-mechanical polishing （CMP）, we have investigated the formation mechanisms of silica gel from a colloidal silica slurry using a membrane filtration system. And besides, for recycling the wet silica gel as a fine silica powder, the experimentally formed wet silica gel was heat-dried and also freeze -dried, and then the micromorphology, specific surface area and pore size distribution of the obtained powders were investigated. The basic mechanisms of slurry filtration, including the effects of vacuum pressure and slurry volume, can be explained by Darcy’s Law. The freeze-dried gel sample was transformed to a fine powder, however the heat-dried one became a sintered solid. Our results indicate that, in the plant, the recovered wet silica gel can be recycled as a fine silica powder by a freeze-dry treatment. The specific surface area and the pore size distribution of the powders were significantly affected by the slurry pH.

The majority of off-type plants in in-dica hybrid rice were CMS and its maintainer lines. Discrimination of maintainer and CMS could only be conducted at heading stage. If maintainer and CMS line could be distinguished earlier, it would be useful to avoid yield losses caused by using contaminated seeds. In this study, three pairs of A and B, Minghui 63, and F1 and F2 plants of Zhenshan 97A/ Minghui 63 were used to find
