置换的

All eighteen cups that were retained at the time of conversion surgery remained stable, with no migration and no progressive radiolucent lines, for an average of eighty-five months (range, twenty to 116 months) from the date of the primary resurfacing arthroplasty until the time of the latest follow-up.

The current density peak of brass welded line appeared at -0.012 V, and a porous corrosion film was formed. The electrode was passivated subsequently. The passivation film was made up of Cu2O, CuCl and ZnO. The passivation film dissolved with electrode potential, and displacement deposition took place between Cu and Zn. The copper redeposition on the electrode surface induced the increase of electrode activity and corrosion rate.

黄铜焊缝在电位-0.012V时出现电流峰，腐蚀产物膜多孔、疏松，随后电极进入钝化区，钝化膜由Cu2O、CuCl和ZnO组成；随电位升高，钝化膜溶解，发生铜锌置换反应，沉积的Cu导致活性电对的形成，增加了合金的腐蚀速度；当电位为+0.87V时，电极表面富集了针状锡和锡的氧化物。

The experiment shows the specimen's freezing and thawing repellence of 100% recycled aggregate concrete with city garbage melting slag, compared with specimen of the normal concrete whose coarse and fine aggregate's replacement ratio is 0%,the durability number indexes of using water and cement ratio 0.45 and 0.65 respectively decreased 5.3% and 7.9%,but all can satisfy the lowest index for evaluating freezing and thawing repellence.

试验结果表明，城市垃圾熔渣再生混凝土试件的冻融循环抵抗性与粗、细骨料置换率为0%的普通混凝土试件相比，水灰比0.45、0.65时的耐久性指数分别降低5.3%和7.9%，但都能满足评价冻融循环抵抗性的最低指标。

The paper,according to the analyzing of lead dross reverberator dust,put forward the new technics indium distilling by sulfuric acid leach ing,P204 extraction,sulfuric acid washing,hydrochloric acid reverse extraction,zinc replacement,smelting,electrolysis,casting etc.

研究分析了铅浮渣反射炉烟尘的性质和特点，提出了二段硫酸浸出、P204萃取、硫酸洗涤、盐酸反萃、锌板置换、压团熔铸、电解铸型的提铟新工艺，并进行了全流程的试验研究，明确了各工序的工艺技术条件。

Well, there"s the badge, the extra power and the refinement, but the Matiz is nonetheless a very efficient little runabout and copes with most situations adequately. It"s better-looking than competing five-door city cars, and the Daewoo package, which includes three years free servicing, AA membership and an exchange plan, helps the Matiz make sense too.

确实，配有奔驰车标的A级车动力强劲，做工精湛，但曼蒂姿仍然是一部不折不扣的称职的都市小车，同时，在大宇的配套服务中，还包括三年免费服务，AA会员资格以及汽车置换服务，这使得曼蒂姿的竞争力大大增加。

Study of sapphirine and related mineral association in the high-grade region of the Larsemann Hills, East Antarctica, shows that sapphirine of the area is characterized by its magesio, iron-and aluminum-rich, but silico-poor feature, and the substantial intra-and intergrain changes in compositions. The change is mainly manifested by the Tschermark substitution + Si = 2Al.

通过对南极拉斯曼丘陵含假蓝宝石矿物及有关组合的研究，得知假蓝宝石的成分以富镁、铁、铝但贫硅为特征，其粒间及粒内成分的变化均较为明显，这种变化主要表现为以钙契尔马克代换+ Si = 2Al为主的类质同象置换。

The results show that chromium doped in the lattice of tin sphene substitutes Cr4+for Sn4+,leading distortion of ［SnO6］ octahedral symmentry.Hence the pigment has a broad absorption peak in the range of visible reflection spectrum, its wavelength is 520 nm. Finally,the colour develops chrome tin pink.

结果表明，由于铬的掺杂，Cr4+置换了锡榍石晶格中的Sn4+，使［SnO6］八面体变形，结果导致色剂在反射光谱的可见光520nm周围形成一条宽的吸收带，从而使釉呈玛瑙红色。

The interface wave model for two-layered viscid fluid is proposed to simulate the dynamic properties of the "water-liquefied soil-subliquefied soil" system, which is formed when certain depth of seabed is liquefied.

海床表层土体的物理参数对于整个海床的抗液化性能有很大影响，置换法是有效的防止液化的途径。

In chapter 2, we investigate the structure of finite groups under the condition that all special subgroups are conjugate-permutable subgroups and obtain some sufficient conditions for solvability, Abelian property of finite groups.

第二章主要是利用一些特殊子群的共轭置换性得到了有限群成为可解群、交换群的一些充分条件，改进和推广了文[1]和[4]中的部分结果，有些结果是新的。

Because of the undeniable fact that even the best of these devices are expected to significantly underperform surgically implanted aortic valves, the justification for their use has been designated as compassionate if the patient is regarded by cardiological and surgical expertise as the most significant or as having an unacceptably high risk for open heart surgery.

一个不争的事实是：即便是最好的经皮植入瓣膜也不如外科手术置换瓣膜效果好。经皮植入人工瓣膜的使用只适用于那些心内科和心外科专家认为开胸手术会有很大风险的患者。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
