The expression of vascular endothelial growth factor mRNA in the demineralized group with PGA at day 14 was the highest.

在脱矿组，PGA组形成软骨的能力早于EMD组，移植后14天，PGA组出现VEGF的高表达。

The results show that the major crystalline phases present in the Noranda copper slag are fayalite, magnetite, copper matte, glassy phase as well as small amount of metallic copper.

结果表明，诺兰达铜渣的主要矿相为铁橄榄石、磁铁矿、铜锍、玻璃相和少量金属铜。

The main points andcontent of the paper are indicated as following:(1) Producing cobalt matte by carbothermal reduction and pyritesulfuration of nickel converter slag at high temperature A mineralogical study of coverter slag shows that the most of cobaltand nickel exist in fayalite of a kind of silicate minerals as a form ofoxide and the rest of cobalt and nickel and most of copper in slag assulphide.

论文的主要研究内容和结果如下：(1)转炉渣高温还原硫化制备钴冰铜转炉渣的矿物学研究表明，在转炉渣中大部分钴、镍以氧化物形态"溶"于铁橄榄石等硅酸盐类矿物中，其余钴、镍及大部分铜以硫化矿形态赋存于转炉渣中。

Through the research, we found that the appropriate readjustment India ore and the Yangchun ore allocated proportion, uses the iron material match level 4 to carry on sinter under the unchanged iron material and craft condition, produces the much calcium ferrite and fayalite, obtains the melting corrosion structure and the granular structure as primarily sinter which may enhance the strength.

凡在烧结时能产生较多的液相，冷却时不是形成结晶较差的玻璃质，而是形成充分结晶的针状或树枝状、棒状铁酸钙；磁铁矿不是以块状孤立存在，而是被粘结相交织固结成熔蚀结构、粒状结构或共晶结构；气孔较少，且分布均匀；粒度较细；组织结构均匀的烧结矿均能提高质量。

The flotation mechanism of MG reverse-floating dolomite was studied by measuring the Zeta-potential of collophanite and dolomite, Infrared Absorptions Spectra analysing the adsorption of MG onto the minerals surface, ultraviolet- visible light absorbing spectrum calculating the amount of MG which was adsorbed onto the minerals surface. These researches showed that MG was more easyly adsorded onto the surface of dolomite in feeble acidic solution because of pure dolomite charges positive as well as pure collophanite charges negative. Therefore, a lot of MG negative ions was adsorded onto dolomite, and that MG negative ions contained hydrophobic group, the hydrophobicity of dolomite was modified, the grains of dolomite were adhered to air bubble and float with them.

对白云石和胶磷矿的Zeta-电位测定、红外光谱分析MG药剂在矿物上面的吸附情况、紫外-可见吸收光谱测定矿物上MG的吸附量等，研究了MG药剂反浮选白云石的浮选作用机理，表明在弱酸性条件下，由于白云石表面荷正电而胶磷矿表面荷负电，带有羧基和羟基官能团的MG药剂更容易吸附在白云石上，使其周围吸附有大量的MG负离子，而MG负离子的另一端为烃基，这就改变了白云石的疏水性，使其矿粒容易附着于气泡上浮。

Aimed at the low screening efficiency of Aiyou Coal Preparation Plant,some technical reforms were done,namely,proper coal feed rate,fitting position of feed trough and regular analysis of screening efficiency ,and the screening efficiency was obviously increased.
