RESULTS: Sixteen weeks later, the CR tablets showed that in the normal group, joint space was normal, and the articular facet was complete and smooth with no osteophyte; in the model group, the medial space was obviously narrowing with obvious osteophyte.

结果：干预16周后，CR片显示正常对照组关节间隙正常，关节面平整光滑，无骨赘；模型对照组内侧间隙明显变窄，有明显骨赘。

Cr doping at B-site could decrease the cathode overpotential without great loss of electric conductivity.

虽然Cr掺杂会小幅度降低〓的电导率，但同时，它也能够降低〓阴极的过电位。

The results showed that the high strength of the alloy mainly came from the pre-cold deformation, the substructure strengthening resulted from aging and the precipitatation strengthening of Cr particles precipitated from oversaturated solid solution.

结果表明：合金的高强度主要来源于预冷变形和时效过程中引起的亚结构强化和从过饱和固溶体中析出Cr粒子引起7的析出强化。

The result shows that Co and Cu are associated with exchangeable fractions, which represents stonger mobility;Pb in iron-manganese fraction represents stonger potential mobility;Zn and Cr existed in oxidizable and residual fraction and Ni in residues represents weak mobility or immobility.

研究结果表明：Co、Cu、Mn存在可交换态，表现有相对较强的迁移性和生物可利用性；Pb主要以还原态的形式存在，表明具有较强的潜在危害性；Zn、Cr主要以氧化态和残渣态形式存在，Ni主要以残渣态的形式存在，这些元素的迁移性较弱。

The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.

结果表明：不同区域环境中重金属呈现不同程度累积，其中以Cu、Ni最为显著，含量由高到低依次为尾矿坝排污沟＞尾矿坝＞废渣堆＞农田土壤；尾矿砂和沉积物中重金属分布以Ni含量显著高于Cu含量为特征；而农田土壤和风化物及降尘中重金属分布以Cu含量高于Ni含量为特征，前者Cu、Ni主要来源于尾矿，后者与冶炼烟尘排放有很大关系；样品中除Cr、Zn以残渣态为主外，Cu、Ni、Pb化学形态分布有较大差异，Cu以可氧化态和残渣态为主，Ni以可还原态为主，其次为弱酸提取态，Pb以可还原态为主，其次为残渣态。

Geochemical analyses include 'total'(concentrated HNO3 -HCl digestion) and chemical forms (three step sequential digestion, reducible, oxidizable and residual forms) of heavy metals Cu, Zn, Pb, Cr,Fe and Mn, iron oxides dithionite-citrate-bicarbonate (DCB and ammonium in the dark extraction as the estimation of total and amorphous iron oxides, respectively, total sulfur and organic matter.

化学分析包括重金属（Cu、Zn、Pb、Cr和Fe、Mn）"总量"（浓HNO3、HCl提取，非严格的总量）、形态（三步提取法，可还原态、可氧化态和残渣态）、氧化铁（连二亚硫酸钠－柠檬酸钠－重碳酸钠提取和草酸铵提取分别估计总氧化铁和无定形氧化铁）、总硫和有机质，并比较了DCB提取前后样品磁性特征的变化。

探讨了Cr部分取代V对TiMn基贮氢电极合金活化性能的影响，并对合金电极的微观组织进行了分析和讨论。

The influences of partial substitution of Mo for Cr of TiCr1.8 alloys on structure and hydrogen storage characteristics were investigated by means of XRD, SEM and PCT.

采用XRD、SEM和PCT法研究Mo取代TiCr1.8合金中的部分Cr对其结构和储氢性能的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
