The characterization of rare earth compound powders,such as rare earth hydroxides,rare earth carbonates,rare earth oxalates and rare earth oxides,are important to the synthesis of rare earth new materials.

稀土粉体(氢氧化稀土、稀土碳酸盐、稀土草酸盐、稀土氧化物和氟化物等)的颗粒性能方面的指标对稀土新材料的开发具有重要意义。

There are three suggestions are further proposed by the researcher: investigating the amount of Chinese rare book, their damaged types, and the existing book restoration resources within the country, devising a standard operation for recording the process of Chinese rare book restoration, and improving the education and training of Chinese rare book conservators.

最后，根据研究者在研究过程中对古籍修复作业的观察与了解，加上技术知识保存的研究分析，提出对古籍修复作业及其技术知识保存的建议，包括调查国内古籍数量、损伤情形及现有古籍修复相关资源、撰写古籍修复作业记录与积极培养古籍修复人才。

In this paper, nanopowders of rare earth oxides and tungsten were prepared and 0-3 type nano-composit rare earth tungsten thermionic emission materials were fabricated with novel technics. The raw material selection, preparation technic parameter, structure, physical and chemical characteristic, the rare earth distribution and the emission behavior were studied. The influence between the active layer and the thermionic emission performance, rare earth elements diffusion and distribution along depth were investigated in detail. The surplus RE formation and the electron transfer were discussed in theoretically. The thermionic emission current density of the single surplus RE on the active layer was educed. We adopted "liquid-liquid mixing, freeze-drying and two stage-reduction" working step firstly to produce the RE-W nanopowders including La-W powder, Ce-W powder and Y-W powder.
