With strengthening of geological and mineral exploration, a great deal of strip mines and near surface mine hare been be found out. It is more and more difficult to find great metallic ore deposits in shallow subsurface(first deep space:0~500m depth).On the other hand, the shortage of metallic ore resources becomes more and more serious.

随着找矿勘探工作程度的不断深入，许多露天的和近地表的金属矿产资源已基本上被查明，在地表浅部（第一深度空间：0～500 m深度）找到大型或超大型金属矿床的难度将必越来越大，而金属矿产资源的短缺已在日益加剧。

For metal lens, we analyze the characteristics of imaging in the same way with left-handed lens, we separate the metal imaging system into to part : symmetric and asymmetric structure.

After testing on the material compositions which effect the metallic yield in the production of terbium metal , as well as the processing parameters during different stages in the reaction process, the technical conditions which can gain best metallic yield in terbium metal production are defined.

针对影响金属铽制备过程中金属收率的原料成分及反应过程不同阶段的各项工艺参数进行试验，确定了金属铽生产中获得最佳收率的工艺条件。

As metal ions can interact with both of ADM and DNA, they undoubtedly affect the interaction between ADM and DNA. Addition of a large excess of Cu or Fe into a solution of well-formed ADM-DNA complex makes the metal ions simultaneously bind to ADM and DNA to form a ternary complex. Otherwise,〓 or 〓 complexes can bind directly to DNA to form a ternary complex.

金属离子-ADM-DNA三元体系的光谱研究表明，当ADM与DNA结合后，大量Cu或Fe的加入可以使金属离子进入到ADM-DNA复合物中，并同时与ADM和DNA键合，形成三元复合物；反之，若ADM先与Cu或Fe配位，生成的金属配合物则能够直接与DNA结合形成三元复合物。

During a long period, cobalt is thought to be a good binder due to good wetting properties, but its present price is as high as 720 yuan per kilogram, so the study of substituting Co diammd tool is an important subject in our country.

长期以来，金属钴被认为是金刚石工具中最好的粘结金属，但由于金属钴其价格和供应极不稳定，目前市场价格高达720元/kg，所以研究代钴金刚石工具是国内研究者正进行的一个重要课题。

It was proved that the mathematical model could be used to simulate the inclusion flotation in tundish.

电磁场对金属熔液中非金属纤维的定向控制金属基纤维增强型复合材料中纤维的取向对复合材料的性能有重要影响。

The oxidation kinetics of depleted uranium was studied in pure oxygen pressure of 5 kPa at below 100°C by using spectroscopic ellipsometry. The relationship of the thickness of uranium oxide with time is measured. The results indicate that below 100°C in the initial period, the relationship between oxidation layer thickness and time is parabolic. The oxidation mechanism of depleted uranium is discussed and the active energy of depleted uranium at given experimental conditions is 87.165kJ/mol from calculation.

采用椭偏技术研究了45~95℃和5kPa纯氧气氛中金属铀的氧化，通过不同温度下金属铀表面氧化层厚度随时间的变化规律，得到贫铀在初始氧化阶段的表面氧化层厚度与时间的关系均呈现抛物线规律；绘制出了在不同温度下金属铀表面的氧化动力学曲线，由此得到在低于100℃，5kPa的纯氧气氛下贫铀表面形成氧化物的反应活化能为87.165kJ/mol。
