The influence of addition of Re species and the preparation methods of the ZrO2 support on the catalytic performance of Ru/ZrO2 and Ru-Re/ZrO2 catalysts for glycerol hydrogenolysis were investigated.

考察了Re组分及ZrO2载体制备方法对催化剂在丙三醇氢解制丙二醇反应中的催化性能的影响。

The massive sulphide, lead-zinc, iron, copper deposits of the former and the porphyry copper-molybdenum deposits of the latter are the main ore types in the region.3. The conclusions drawn through the research on the Re-Os isotopic geochronology of the Chilu Mo deposit are as follows:(1) the model age of the Chilu Mo ore deposit is 105.6Ma, closely to the 87Sr/86S isochrone age of the porphyric granite, adamellite. So they are closely correlated in the genesis, and both are the production of magmatic evolution of the late Yanshan.

Cu、Mo、Pb、Zn、Au为区内优势矿种。3、对赤路钼矿床的Re—Os同位素年代学研究得出如下结论：(1)赤路钼矿的矿化模式年龄为105.6Ma，与似斑状花岗岩、二长花岗岩等的87Sr/86Sr等时线年龄115±4Ma较接近，表明二者在成因上密切相关，同属燕山晚期岩浆演化的产物；(2)赤路钼矿床具有辉钼矿中Re、Os含量偏低，低87Sr/86Sr初始值和硫同位素组成接近陨石硫等特点，表明其为成矿物质来源于地壳深部，且为斑岩型钼矿床。

Based on application state and refinement mechanism of treatment agent of aluminum alloy mele,the paper analyses the effect of rare earth,Al—Ti—B interalloy and Re—AlTiB interalloy on cast structure of aluminum alloy,then the application of compound Re—AlTiC interalloy was studied.

在叙述铝合金熔体处理剂应用现状与细化机理的基础上，分析了稀土添加剂、Al—Ti—B中间合金细化剂以及Re—AlTiB中间合金对铝合金铸态组织的影响，接着对复合添加剂稀土铝钛碳中间合金作了应用研究。

Such an observation can be best explained if Re and 187Os are internally decoupled within molybdenite grains.

这是因为Re和187Os在辉钼矿亚晶粒范围内出现了失耦现象，也就是由于放射性成因187Os的迁移使Re和187Os在空间上不再保持连接。

This dissertation got the deposit forming of Qulong copper porphyry copper deposit by SHRIMP zircon U-Pb and Re-Os molybdenite methods.

对驱龙铜钼矿床进行了锆石SHRIMP U-Pb同位素定年及辉钼矿Re-Os同位素定年，获得新的年龄数据：含矿斑岩锆石SHRIMP U-Pb年龄为16.35～17.58Ma，矿石的辉钼矿Re-Os同位素年龄为15.36～16.85Ma。

Re-Os dating for the same group of molybdenite samples using inductively coupled plasma mass spectrometry and negative thermal ion mass spectrometry determination after sample pretreatment with Carius tube digestion were compared.

对同一地区但Re、Os含量不同的一组辉钼矿样品，分别采用电感耦合等离子体质谱和负离子热表面电离质谱对其Re-Os年龄进行了测定比较。

The addition of Re slightly decreased the formation temperature of MC carbides and promoted the precipitation of μ phase from the oversaturated γ matrix.

Re不进入MC碳化物，Re的加入可降低MC形成温度并促进μ相从MC周围过饱和的γ基体中析出，进而诱发MC不稳定分解。

Based on the Re-Os isochron method of molybdenites, this paper measured directly the ore-forming age from skarn ore in the Huangshaping deposit, and got a Re-Os age of (153.8±4.8)Ma, which is in accordance with the previous K-Ar age of 153~157 Ma obtained from phlogopite in the ore-bearing skarn of the deposit.

文章采用高精度的辉钼矿Re-Os等时线定年法，直接测得硅卡岩型矿体的矿化年龄为(153.8±4.8)Ma，与前人获得的含矿硅卡岩中金云母的K-Ar年龄(153~157Ma)一致。

The results have shown that P-RE-USY has good hydrothermal stability owing to the migration of hydroxy rare earth cation from the super cages to the sodalite cages enhanced by phosphorus addition, inhibiting the frame...

结果表明，由于磷促进了稀土离子由超笼向方钠石笼中的迁移，阻止了沸石在水热条件下的脱铝作用，从而改善了P RE USY沸石的水热稳定性；P RE USY沸石酸性分布更集中在中强酸范围，有利于发生氢转移反应，而强酸数量的降低有利于减少焦炭形成，改善了焦炭选择性。

The composite of Ir/Re was prepared by chemical vapor deposition first in china. Iridium coatings and rhenium substrates were bonded together metallurgically.
