The paper takes the project of Xi'an international airdrome infrastructure management information system as an example and validates its feasibility and demonstrates its applicant value, which realizes the share of infrastructure data and establishes the basic for further development.

在现阶段，由于面向对象数据库自身发展的不成熟和互操作技术的不完善，本文提出采用较为先进的空间数据引擎技术结合关系数据库或对象关系数据库建立统一的数据模型和统一的数据库管理系统，打破空间数据固有的管理模式和界限，实现空间数据和其他属性数据的集成，为地理信息的共享奠定基础。

Linear Algebra is mainly a subject which studies the linear structure of finite dimensional linear space and its linear transformation while linear concept is in itself from the old Euclid Geometry. The concept of "Linear Space" is a kind of algebraic abstract. In many fields of modern engineering project and technology, because of the influence of computer and graph showing, the algebraic disposal of geometric questions, the visual disposal of algebraic questions, algebra and geometry are tightly combined.

线性代数主要是研究有限维线性空间及其线性变换这一代数结构的学科，而线性概念究其根源则是来自古老的Euclid几何，线性空间概念是几何空间的一种代数抽象，在现代工程技术的许多领域里，由于计算机及图形显示的强大威力，几何问题的代数化处理，代数问题的可视化处理，把代数与几何更加紧密地结合在一起。

Determinants and their properties are also introduced. After review of the algebraic structure of the Euclidean space, the algebraic vector space then will be studied.

再复习欧几里德空间的一些代数性质与几何，然后学习向量空间与向量空间的性质。

In this paper, we have made a systemic theoretic research on modelling and reshaping several types of spline curves/surfaces in CAGD. And some creative productions are given as follows. At first, the uniform C-B-spline basis is proved to be a normalized totally positive basis, and can be extended to a normalized B-basis. C-B-spline and C-Bézier basis, similar to B-spline basis and Bézier basis in algebraic space, are two bases in algebraic trigonometric space.

本文围绕着CAGD中常用的几种曲线曲面造型和形状调整进行了深入的研究，主要获得了以下一些成果：首先，证明了代数三角空间中的n次均匀C-B-spline基是一组标准全正基，并进一步扩充为一组标准B基。C-B-spline基与C-Bézier基是多项式与三角混合空间中的两组基，是适应工程实践中设计特殊曲线曲面的需要而产生的，类似于多项式空间中的B-spline基与Bézier基，是CAGD中重要的造型工具。

Our research aims to research and design an spectrometer-identificator to simultaneously or separately detect the fluxes and spectra of protons, alpha particles, oxygen and iron ions distributed in space.

为了满足当前空间环境的探测需要，需要研制一台全频道的空间带电粒子探测谱仪，该谱仪能够同时测量空间质子、α粒子和重离子的能谱和通量分布。

We may conceive an analysis situs graph, in a spatial on observation is such, observes in addition on spatial or such, what is different, in two spaces is the masculine and feminine elements, saw in the positive spot cloudy, saw in the cloudy spot positive.

我们可以设想一个拓扑图形，在一个空间点上观察是这样的，在另个空间点上观察还是这样的，不同的是，在两个空间是阴阳的，在阳的点看到阴，在阴的点看到阳。

In spatial analytic geometry,a spatial curve is an intersecting line of two curved surfaces.

在空间解析几何中，空间曲线是两曲面的交线，在空间曲线中消去一元，即得投影柱面。

One pace teachs me to make a station, arrive from the domain name space, from analytic to upload, arrive from HTML CMS, I what let do not have a technology also made a way station, the scene warbling of the oriole at that time is in eye, a website from begin conception to build SEO, true, very excited, I am very clear remember these courses, begin corn of bought a CN, with the space of a 100M, spent 76 yuan, 75 yuan space, 1 yuan rice

一步一步教我做站，从域名到空间，从解析到上传，从HTML到CMS，让没技术的我也做起了一个小站，当时的情景呖呖在目，一个网站从开始构思建设到SEO，真的，很兴奋，我很清楚的记得这些过程，开始买的一个CN玉米，和一个100M的空间，花了76元，75元的空间，1元的米

Say me put on record process, sichuan (of Sichuan put on record faster) such-and-such interconnection is not to have permanent and free free space applies for, go applying for a free space first, next the domain name analytic the IP to free space, go putting on record next cough up (the id card that here wants to use Sichuan, oneself think) of method cough up, put on record how to filled me not to say more, won't can look for a tutorial to look.

说一下我的备案过程，四川的某某互联不是有永久免费的的免费空间申请么，先去申请个免费空间，然后把域名解析到免费空间的IP，然后去备案咯(这里要用到四川的身份证，自己想办法咯)，备案怎么填我就不多说了，不会的可以找教程看哦。

Because of the superposition and anastomose between investigation space and city space in the study, the paper take use of the theory and concept of the relationship between human-being and land the idea of special analysis to explain WTP.

在本论文中，由于调查空间与城市空间的重叠和吻合，采用了人地关系和空间分析的理念来解释WTP。

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。
