The density, electrical contact resistance and hardness of these two alloys were tested. The results show that Ag and rare earth oxide appear in Ag-Y and Ag-Ce alloy after internal oxidation. The distribution of oxide particles is inhomogeneous and seriously conglomerated in Ag-Y2O3 and Ag-CeO2 sintered bulk, but they are dispersed and uniform in Ag matrix after severe plastic deformation. The relative densities of wire materials are larger than 99% and the electrical contact resistances are low (＜2.2 μΩcm).

结果表明：Ag-Y和Ag-Ce合金粉末经内氧化处理后生成Ag和稀土氧化物2种物相；Ag-Y2O3和Ag-CeO2材料烧结坯中氧化物颗粒分布不均匀且团聚严重，但材料经过大变形加工后，氧化物颗粒细小，均匀地弥散分布在银基体上；最终产品丝材的相对密度均达到99%以上，电阻率较低(＜2.2 μΩcm)。

The minerals of igneous formations were described and a bulk volume model based on mineral and including porosity was established. The logging response equations of density, apparent neutron porosity, acoustic travel time,gamma ray and volume photoelectric cross index were deduced. The volume content of four minerals in matrix was calculated. The igneous rocks were classified according to the international igneous classification scheme proposed by IUGS (International Union of Geological Society).
