In this section, applying the method, from abstract to specific and from history to present, it analyzes the operation mechanism of urbanization economy affected by market mechanism; puts forward four theories of urbanization economy from economic perspective, including agriculture surplus and comparison advantage; non-agricultural industry; agglomeration economy and spillover effect, on this basis of the theories, it, on one hand, analyzes two kinds of internal mechanism in the chronologic operation of urbanization economies: increasing mechanism of urbanization economies in urban output industry; and changing mechanism from specialization to integration, which are the representations of the evolution of "mart" development; on the other hand, it analyzes two internal mechanism of dimensional operation of urbanization economy: internal spatial enlargement mechanism of urbanization economies from monocentric city to multi-center city, and external spatial enhancement mechanism which represents city-regionalization and city-chain connection, the later two mechanism represent the evolution of "polis" development.

这一部分，按照由抽象到具体和由历史到现代的研究方法，分析了市场机制作用下的城市化经济运行机理，从经济学角度提出了农业剩余与比较优势、非农产业、聚集经济、外溢效应四大城市化经济定理；在此基础上，一方面分析了城市化经济运行沿时间增长的两个内在内容提要机制：城市输出产业的城市化经济增长机制和从专业化到综合化的城市性质变迁机制，它们主要表现为&市&发展的延续；另一方面分析了城市化经济运行沿空间增长的两个内在机制：从单中心到多中心的城市化经济运行的内部空间扩展机理和表现为城市区域化、城市连绵体的城市化经济运行的外部空间扩展机理，它们主要表现为&城&发展的延续。

In the feature space,the divergences on two classificational distributions are only dependent on the two characteristic vectors,i.e.,maximun and minimum in feature values,and their varying values depend upon the declinations of the aforementioned two ...

Crystal structural analysis reveals that, because water molecules bond to Cu atoms, the dhbd ligand can only adopt a hydroxyl oxygen atom to bridge two reversed U-shaped subunits into a novel centrosymmetric dual-U-shaped tetranuclear Cu structure. Each U-shaped frame consists of two crystallographically distinct Cu atoms, two dpphen ligands and one coordinated water molecule.

晶体结构分析表明，由于水的配位阻断， 2，3-二羟基丁二酸根仅通过单羟基氧桥联两个U形双核亚单元形成具有一个对称中心的双U形四核结构，其中U型亚单元包含晶体学上不对称的2个Cu原子、1个2，3-二羟基丁二酸根、2个4，7-二苯基-1，10-邻菲咯啉和1个配位H2O分子。

This product was listed on the end of 2007, incorporates the industry's original Bi-ink double-charged print head technology, two lines of black line up the print head nozzles disnature width to one-inch, print range is from the past two times, the same print area, the sprinkler head General printer requires two round trip, but an C110 to complete.

这款产物2007年不顶上市，拔取了业边步武的独黑墨打印脚Bi-ink技艺，两动白色喷嘴错位摆列，打印脚宽度也扩不小为1英寸，打印边界是畴前的两倍，同样的打印地区，凡是打印机必给喷脚行两个单程，而C110功一次不离可达成。

Results The two methods had the positive effects on BPH patients, the IPSS and urinefollow-metry rate were improved obviously in the two groups, and the curative effects of tamsolusin was much better than ERTH in the improvement of IPSS, but the urinefollow rate improvement in the two grpups was not significantly different.

结果两组病人对热疗和α1A受体阻滞药物的治疗均有肯定的疗效，与治疗前对照症状及尿流率显著改善；盐酸坦索罗辛的IPSS改善优于热疗组，尿流率的改善程度两组相似，差别无统计学意义；两组病人并发症均较轻，多为一过性，并未影响治疗。

On the basis of deep analysis on the relation between two judgments on human nature, intellectual virtue and moral virtue, a good people and a good citizen, the relation between the two judgments of eudemonia is explained. That eudemonia is an activity of soul in accordance with perfect virtue is just a tache which links two kinds of eudemonia. Their internal relation also shows the combination of idealism and realism.

在深入分析&人的本质&的两个论断、&理智德性&与&道德德性&、&好人&与&好公民&的关系基础上，两种&幸福&的关系得到了说明：&幸福是灵魂的合于完满德性的实现活动&成为联结二者的纽节，其内在的紧密联系也体现了亚里士多德对&幸福&的理解中理想主义与现实主义精神的结合。

With the development of molecular biology, based on yeast two-hybrid, many techniques such as yeast one-hybrid, reverse two-hybrid, three-hybrid, and extranuclear two-hybrid were set up to be applied in the research on the interaction between protein-protein, protein-DNA, protein-RNA, and protein-ligand.

随着分子生物学的发展，在酵母双杂交的基础上又建立起了酵母单杂、反向双杂交、三杂交及核外双杂交等多项技术，并已经成功地运用于蛋白质之间、蛋白质与DNA、RNA和配体之间相互作用的研究。
