According to the differences in chemical and structural characters of WO42- and MoS42- the actions of them to separator molecular such as bonding, hydrophile/hydrophobia and geometry are discussed by using mineral flotation as reference.

以相似元素钨和钼的分离为例，根据WO42-和MoS42-的结构特征，从价键因素、亲水-疏水因素、几何因素等方面分析了它们与吸附剂的作用，成功选择了有色金属硫化物作为选择性吸附剂，实现钨和钼的高效分离，并进一步探讨了吸附剂的改性优化和其它类似元素的深度分离问题。

Administrative jurisprudence analyse logic fundamentally moves forward from subject and object logical relation,state will expression and state will ution logical relation,individual and public interest logical relation,behavior regulation and standard system logical relation,involved element and designed element logical relation.

行政法学分析逻辑的基本进路包括从主体与客体的逻辑关系进行分析、从表达国家意志与执行国家意志的逻辑关系进行分析、从个体利益与公共利益的逻辑关系进行分析、从行为规则与规范体系的逻辑关系进行分析、从介入元素与设计元素的逻辑关系进行分析。

The modern graphic design skeleton requires many kinds of artistic elements to support. Speaking of traditional Chinese painting , one form of China's traditional culture art, the perfect union of its traditional culture spirit, the words technique, methodicalness layout and a series of artistic experience and the theories, as well as visual elements such as poem, calligraphy, painting and seal has a significant influence and model function to the modern graphic design .

现代平面设计的构架需要多种艺术元素的支撑，就中国的传统文化艺术之中国画而言，它的传统文化精神、笔墨技法、章法布局等一系列艺术经验和理论，以及诗、书、画、印等视觉元素的完美结合对现代平面设计的影响与借鉴作用是重大的。

A one - to - one correspondence between the elements of two sets such that the result of an operation on elements of one set corresponds to the result of the analogous operation on their images in the other set.

同构的两组元素的一一对应的关系，这种关系使得对其中一组元素进行运算的结果对应于对它们在另一组中的像进行类似的运算所得的结果

We summarize the study of geochemistry of the Co rich crust, and explain the diffusion of elements in the Co rich crust and the exchange with ambient seawater. Besides, we discuss the effect of phosphatization and substrate rocks on the composition of the Co rich crust. We also introduce the application of stable isotopes (including the stable isotopes of Pb, Nd, and Hf), radioactive...

概述了富钴结壳地球化学的研究成果阐述了富钴结壳中元素的扩散及与周围海水的交换，基岩和磷酸盐化事件对富钴结壳组成的影响分别介绍了稳定同位素(Pb、Nd和Hf的稳定同位素)、放射性同位素(Be、U和Th的放射性同位素)及元素(常量和微量元素、稀土元素)在富钴结壳古海洋学研究上的应用。

Following are summary of our works:(1)The powders of LaCr_(0.9)Co_(0.1)O_3, LaCr_(0.9)Fe_(0.1)O_3, LaCr_(0.9)Ni_(0.1)O_3, LaCr_(0.95)Sn_(0.05)O_3 and LaCr_(1-x)Ti_xO_3(x=0.0-0.3) were single perovskite phase with orthorhombic structure. The gas-sensing properties of their thick film sensors were tested in the acetone, ethanol, normal propyl alcohol, carbinol and formaldehyde organic gases. The sensitivity of the sensors can not be enhanced effectively by doping Co、Fe、Ni、Sn elements in B-site of LaCrO_3. Ti dopant with proper concentration can greatly improve the gas-sensing properties, which make the sensor display higher sensitivity and quicker response-recovery characteristics.

所得结果摘要如下：(1)LaCr_(0.9)Co_(0.1)O_3、LaCr_(0.9)Fe_(0.1)O_3、LaCr_(0.9)Ni_(0.1)O_3、LaCr_(0.95)Sn_(0.05)O_3和LaCr_(1-x)Ti_xO(来源：ABfd1dC论文网www.abclunwen.com)_3(x=0.0-0.3)粉体为正交单相钙钛矿结构，其厚膜型气敏元件在350℃时对丙酮、乙醇、正丙醇、甲醇、甲醛等有机气体的气敏性能测试表明：0.1mol Co、Fe、Ni和0.05mol Sn元素在LaCrO_3的B位进行掺杂后，不能有效提高材料对以上测试气体的气敏性能；而Ti元素的适量掺杂可以极大地改善LaCrO_3的气敏性能，使之显示出对丙酮气体的高灵敏度和快速响应恢复能力。

By means of a resonable and approximate treatment the dependent variables of the integral equation are reduced to depend only on the two coordinates of the wing plane.

通过合理的近似处理，使积分方程的自变量仅依赖于机翼所在平面的两个座标，这就使我们在利用有限无法进行数值解时，只需在机翼平面上划分元素，避免了在流场空间中划分元素的传统作法，从而大大降低了对计算容量的要求和计算工作量，使跨音速三维机翼的气动力计算有可能在较小的计算机(例如709机)上完成。

After staving these samples, the authors determined and analyzed 7 kinds of trace elements in them. The authors think that the intake of amounts of all elements or one special element is different in differe...

结果表明，大熊猫在不同时期对 7种元素的总量或某一种元素的摄入都不相同，这是通过选择不同的食谱即改变食性而实现的，并由于各期有不同的生命活动所引起的。

In section 1.3, taking the advantage of the classification by the index arrays ,pointed out the space spanned by class A,B,C respect!vivety are subalgebras of NQ. We also show that the subspace spanned by the elements of length 2 in C is an abelian subalgebras of NQ,denoted by H.we find H is contained in the center of subalgebra P of the subspace spanned by the elements in class C.

在1.3节中，应用指标数组我们讨论了各类元素的性质，指出其第A，B，C类元各自张成的子空间均是N_Q的子代数，特别是C类中所有长度为2的元素张成了N_Q的Abel子代数H，且含于C生成的子代数P的中心Z中。

When we add 5 to p, the effect is to calculate the address of that is five ints away from pin other words, p + 5 points just past the end of arr.

p 加 5 即得 p 所指向的元素后面的第五个 int 元素的地址——换句话说， p + 5指向数组的超出末端的位置。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
