In this paper, the granule characteristics of limestone powder and the influence of stone powder content on the properties of RCC in Longtan Hydropower Station were studied, it was found that the workability of RCC would not be affected if replacing a part of fly ash with stone powder, but the compressive strength of RCC would decreased slightly.

为此，结合龙滩工程大坝碾压混凝土的特点，研究了石灰岩石粉的颗粒特性以及石粉含量对碾压混凝土性能的影响，发现用石粉取代部分粉煤灰不影响碾压混凝土的工作性，仅会使碾压混凝土抗压强度轻微下降。

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.
