The results are displayed vividly in virtual scene which is established with program language of Visual C++ and OpenGL. At present flow field simulation manner mostly has time delay, deficient controllability, so this paper brings forward the methods of drawing flow velocity vector graphics with OpenGL in the 3D virtual scene to simulate and analyze flow field. At the same time cross section and flood analysis are completed. Accordingly, it assists flood flow field visualization and provides the more effective analysis method for the flood mathematics model research and application.

By anchoring an imaginary spring between each data point and deformable curve or surface, the fairing model is established. Then FEM is used to solve the deformation problem of the model caused by imaginary springs and a bicubic B-spline surface patch is taken as one element. Lastly the B-spline active surface model is applied to surface reconstruction from layer data and the problem resulted from fitting for uneven cross-sectional curves can be solved.

通过在数据点与模型之间连接虚拟弹簧，建立光顺模型，并以双三次B样条曲面片作为单元，运用有限元法对模型在虚拟弹簧作用下的变形问题进行求解，得到光顺后的B样条曲面；并在此基础上，提出了一种新的基于断层数据的表面重建方法，可很好地解决不均匀截面族的曲面生成问题。

At last, there are some immaturely proposals for us to deal with the problems of the oldest-old in China: the first is enhancing a sustained development of the economy; secondly, making some feasible laws and systems; thirdly, cultivating the all-around oldest-old awareness; fourthly, making the age-providing system and medical system that has Chinese characteristics; fifthly, we should pay more attention to the female oldest-old in the country.

最后，我们应该从以下几方面努力在解决中国高龄老年人口问题：一是加快社会经济的可持续发展，二是制定切合中国高龄老年人口实际的法律和制度，三是培养全民的高龄意识，四是构建有中国特色的养老体系、医疗体系，五是对农村女性高龄老年人口进行重点政策倾斜，另外还应适度改革现行生育政策，发展适应高龄老年人口的保险等等。

Using differential calculus knowledge to testify inequality, Calculus of higher mathematics is the core and calculus method of higher mathematics is typical of the whole mathematical method, the method is introduced for calculus ideas to solve the problem of finding an inequation, to make way for obtaining inequalities can be simple, the application of differential mid-value theorem and Taylor formula illustrate some of the inequality proof method.

运用微分学知识证明不等式；微积分是高等数学的核心，微积分思想方法是高等数学乃至整个数学的典型方法，微积分思想方法的引入为解决不等式证明的难题找到了突破，用来解不等式可使解题思路变得简单，文章应用微分中值定理及泰勒公式举例说明了部分不等式的证明方法。

Here are strategies for radically solving it: As for the types, its achievement can be realized from the aspect of politics, law, moral and practice; as to the legitimacy of history, the success that the CPC has made is not "changing the dynasty" or "controlling the power quickly" in the traditional sense; as for the cultural meaning,"ruling for the people" is the essential value judgment for the ruling legitimacy; as to the historical experience, it is requisite to be concerned about "the doctrine of innateness" or "the theory of gaining lasting repose once and for all" about the ruling position and its legitimacy; developing the cultivating inner democracy within the Party and drawing on and keeping in mind the historical experience all need to be taken into consideration.

就类型而言，可从政治学、法学、道德、实践诸方面认识执政合法性的取得；从历史合法性看，中共革命成功非中国传统意义上的"改朝换代"和"马上得天下"；从文化意义上看，"执政为民"是执政合法性的根本价值判断；就历史经验看，忧虑执政地位与执政合法性的与生俱来说和一劳永逸成为必然；发展和培育党内民主、借鉴和牢记历史经验都是值得深切思考的，这是从根本解决长期执政合法性问题的基本策略。

Vietnam is still dealing with the aftermath of war and the United States should help, but the conflict wasn't all bad because it forged the unified socialist country that exists today, the powerful Communist Party chief Le Kha Phieu was quoted as telling President Clinton who's on the last leg of his historic three-day visit.

越南共党总书记黎可漂在一段对来访的美国总统克林顿的谈话中表示，越南目前仍在处理越战战后的问题，而美国则应协助越南解决相关事宜，但尽管如此，由于冲突打造了现存的这个统一的社会主义国家，因此冲突不全然是坏事。
