Libermann.The early researcheson this kind of manifolds were closely related to Physics and Mechanics.But since1991,S.Kaneyuki published his result on the algebraic condition for the existence ofinvariant〓structures on a coset space,Lie theory has played the most impor-tant role in the study of this kind of manifolds.In particular,dipolarizations in a Liealgebra are closely related to the homogeneous〓manifolds.Dipolarizationsin semisimple Lie algebras and the homogeneous〓manifolds associated withthese dipolarizations have been studied by S.Kaneyuki,Z.X.Hou and S.Q.Deng.Inthe partⅡ of this thesis we study the dipolarizations in some quadratic Lie algebrasand the homogeneous parakahler manifolds associated with these dipolarizations.

Libermann给出的，早期的有关类流形的研究与物理和力学密切相关，自从1991年金行壮二发表了陪集空间上存在不变仿凯勒结构的代数化结果后，李群及李代数理论在这类流形的研究中起着主要作用，特别地，李代数的双极化与这类流形密切相关，半单李代数的双极化的相关几何，金行壮二，候自新和邓少强等人已作了研究，二次李代数是比半单李代数更广且带有非退化不变双线性型的李代数，本文主要研究了二次代数的双极化及相关几何。

It can be used to effectively stop a grappler in his tracks and provide the space you need to launch a counterattack .

Research about China must study her control approach, because in human history, you cannot find another one like Chinese culture, which has been entirely controlling the citizen抯 life not only in political and conscious level, but also the substantial and spatial realm coving from macro-scale urban planning, through the traditional architectural construction regulation, to every sophisticated detail of daily life since thousands of years ago.

研究中国必须要研究其控制方式。因为历史上恐怕再难找到像中国文化这样，在几千年中如此事无巨细地讲究控制，不仅是在政策和意识形态上，并且也是物质化和空间化的：从城市规划的宏观规则，建造营造的中观法式，到生活用品的每一个微观细节。

He shows what is covered by cultural and living surface phenomena very clearly and leads readers to walk out of the ring upon ring dense fog of the commercial, technological and cultural coxcombical times on the way he showed in his novels to enter a simple and attracting ideal existence space.

他把文化和生存的表象遮盖下的东西异常清晰地显露出来，引领读者循着他在小说中展示的道路，走出商业、技术和文化虚浮时代的层层迷障，进入素朴的醉人的理想的生存空间。

It provided a correct and reasonable mathematical model for the analysis of the ultimate bearing capacity and crankle stability of the thin-walled structure.

论文在比较了两种运动描述方法（完全拉格朗日法和更新拉格朗日法）异同点并分析了非线性几何关系及大变形下的弹性物理关系的基础上，基于增量虚功原理推导了几何非线性空间梁元单元切线刚度矩阵，采取分模块形式，分别表示了轴力、弯矩、双力矩对几何矩阵的贡献；通过球面显式荷载增量迭代式弧长法求解方法编制程序，很好地实现了几何非线性增量荷载的自动步长选择及全过程跟踪，为薄壁杆系结构的极限承载力分析和弯扭失稳分析，提供了较为精确合理的分析力学模型。

Research usejP.Haggett"s pattern of spatial structure and system, analysis technique of tourism market space and data of spot check to analyze the evolvement of spatial structure and problems of tourism development from six faces, move, path, crunode, significance of crunode, ground and diffuse. The law of the evolvement of spatial structure: First, tourism development keeps rising. Second, AR of xi"an is very big and stable, Xi"an is tourism hotspot and center. Third, origin market space sticks out east, and isn"t continuous. Fourth, tourist proportion of XAZ follows the low of distance decay. Distance decay is very obvious in adjacent zone because of little attraction. Sixth, the spatial distribution of tourist origins has become less concentrated. Tourist origins of east China develop quickly. Three problems: First, tourism development is very unbalance between Xian and its adjacent zone.

西安及毗邻地区的国内客源市场空间结构的研究，采用了英国著名地理学家哈格特描述的空间结构模式与秩序，利用旅游市场空间分析技术，借助市场抽样调查、数量分析，从运动模式、路径、结点、结点层次、地面和扩散6个层方面进行了剖析，归纳总结出5个客源市场空间结构演变规律：(1)旅游业发展整体保持增长趋势；(2)客源吸引半径大而稳定，西安市是全国性的旅游热点城市和旅游中心城市；(3)客源市场分布突向东部，呈不连续分布；(4)游客比重的距离衰减普遍存在，毗邻地区吸引物及自然吸引物吸引力较小，距离率减明显；(5)客源集中度减小，客源市场发展呈现跳跃式增长的演变规律。3个市场拓展面临的问题：(1)西安与毗邻地区间旅游业发展不平衡现象明显；(2)客源市场区位不佳；(3)旅游产品单一老化，类型单调乏味。

At and , we can get a univariate cubic equation in and its three roots . By the dependence of the roots and the coefficients of the equation, we can choose corresponding space points ( such that the distance is the shortest from to the point with parameters and . Thereby we can get all the data of discrete points on the cubic curve of blending surface at . Again we denote the maximum value and minimum value of planar parameter with which meets by and respectively.

利用根与系数的连续相依性，可以选相应的空间点使其距离的圆截线上对应值的点最近的两个根，从而得到处拼接曲面的截线的离散点的数据并确定出与相截的平面参数的最大最小值类似地由处拼接曲面截线的离散数据得到处的离散数据，这样可以依次计算出拼接曲面上对应所有参数点的离散点的坐标。
