A matrix composed of 260 characters and 46 taxa is constructed and analyzed cladistically using the NONA (ver 2.0) software package and formatting and character exploration was performed in WinClada .

通过检验这260个性状在46个分类单元中的分布情况，建立了目前有关虚骨龙类的一个最大的矩阵，采用最新的 NONA 和 WINCLADA 软件，对虚骨龙类的系统演化关系进行了分支系统学分析。

Furthermore, Ptychidio distinctly differed in osteological characters from other genera of Labeoninae, so it wasn't chosen as taxon of ingroup in phylogeny of Labeoninae. And Ptychidio's phylogenetic status can be ascertained only if more taxons of Cyprinidae be chosen and phylogeny of Cyprininae be solved in further research and molecular research.

此外，在特征分析时发现，卷口鱼属同野鲮亚科其它属的骨骼特征相差甚远，所以在分支系统学分析时没有被选择，有关其分类地位的确立，有待于今后在鲤科分支系统学研究中和分子生物学资料的研究中解决。

The generalized reliability of single failure mode component and unit structure under different kinds of uncertainty factors is treated perspicuously and classified. Combined with the three class fortify standard of aseismic design code,the conception of reliability vector of structures and systems with intermediate state before failure is put forward, and the calculation model of reliability vector with three stage working modes of "safety-intermediate-failure" and the operation rules of reliability vector of the simple aseismic engineering systems composed by structures are established.

In this paper, we give explicit constructions and formulations for harmonic maps from R1,1 into classical real semisimple Lie groups by using Darboux transformation. We also discuss pluriharmonic maps from complex manifoldsinto symmetric spaces and Willmore surfaces in Sn. By converting geometric conditions satisfied by these maps into integrable systems, and using the the-ory of integrable systems, we give explicit constructions for pluriharmonic maps from complex manifolds into symmetric spaces and the Willmore surfaces in Sn respectively. Finally, we classify hypersurfaces in Sn+1 with three distinct prin-ciple curvatures and zero Mobius form using the theory of Mobius geometry. The paper consists of four chapters.

本文首先利用Darboux变换的方法给出了从Lorentz平面R~(1，1)到经典实半单Lie群的调和映照的具体构造，并给出其显式表示；其次研究了复流形到对称空间的多重调和映照及球空间S~n中Willmore曲面，将这些映照所满足的几何条件转化为可积系统，然后利用可积系统理论分别给出复流形到对称空间的多重调和映照与S~n中Willmore曲面的构造；最后利用Mōbius几何的理论给出S~(n+1)中具有三个不同主曲率且Mōbius形式为零的超曲面的分类。
