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.

翻修手术时保留的仍然稳定的18个臼杯，在从初次表面置换到最近随访时的平均85个月（范围20至116个月）间，都没有发生移位，没有进行性的X线透亮带。

The first step is selecting a rain gauge as rainfall center by taking turns and adding the nearest rain gauge step by step to estimate the rainfall ratio relation of the same time with respect to the different distance separately. The last step is utilizing Weibull function can inquire into the return periods. Then, the ARF of Tamshui River basin is established.

研究中，先以某个雨量站当成点降雨中心，并逐次纳入邻近雨量站，即可分别得到不同距离下、同时间之雨量比值关系，依序置换不同雨量站为中心进行相同之分析，并利用威伯点绘法，进一步推求重现期距，即可建立研究区域之不同重现期距、不同延时与面积递减关系之ARF曲线。

The frist step is selecting any gage that building in the river basin as rainfall center, and adding the nearest rain gauge step by step to calculate the point and areal rainfall for different size of area. Using different gage that in the river basin as rainfall center can get the result of different case.

研究中，先以某个雨量站当成点降雨中心，并逐次纳入邻近雨量站，即可分别得到不同面积下之点降雨及区域面积降雨，依序置换不同雨量站为中心进行相同之分析，即可得到所有可能组合案例之分析结果，利用Gamma分布可进一步推求不同重现期距之点降雨及区域面积雨量，即可建立研究区域之ARF。

The foundation of wharf apron space was improved by use of special rammer of small base area,gradual tamping energy and dynamic replacement .

强夯置换法综合了强夯加固和复合地基的优点，经济有效，但其夯击能在地基中产生的波场对周围建筑物产生着冲击作用，常常制约着其应用。

Realisable assets also covers portfolio, the existing housing replacement.

可变现资产又涵盖了有价证券、现有住房置换。

That is to express a social retrospection,Da-Yin-Yin-Yu-Shi(Great reclusion is reclusion in city) The works in this exhibition is another type. he tampers and displaces the old political slogan to show the fall between two times and the variable life.

现在所展出的这批作品是他的另一批观念作品，作品借鉴了过去的政治标语，但经过他巧妙的置换与篡改，于不动声色之间呈现出了两个时代的差落，并反诘了由此而造成的人生无常。

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。

Besides adopting venture investment, share investment, ownership of a share displacement, enterprise regroupment and annexation, and various kinds of investment ,our group still fully exerts the strength of our group; makes use of the abundant capital, advanced technology and mature managing principle, and concentrates on Chinese economic developments, which becomes a bridge for economic boundary between China and the USA.

本集团严格遵循国际化、标准化运作模式，除了采取风险投资、股份投资、股权置换、企业重组兼并等多种方式进行投资外，还将充分发挥本集团的优势，运用雄厚的运作资本、先进的科学技术和成熟的管理理念，致力于中国的经济建设，成为架设中美经济界合作的桥梁。
