Since the attenuation of the free-space channel between ground and satellite is contributed by the aerosphere, its equivalent length is about 5 km and the total attenuation of round-trip is equivalent to 10 km free-space channel in the earth surface aerosphere.

由于地面-卫星之间的自由空间信道的衰减主要集中在地面大气层，其等效厚度约为5km，往返两次的信道衰减等效于地面大气层的10km。

In this paper,the area ratio of plane figure affine transformation in space is investigated,and the transformation equation of λ multiple of area is got , the area change of plane figure under affine transformation in space is studied, a important property of three axis ellipsoid is given and proved.

Tetrahedron can be formed with four sequence and non-coplanar points in space,and any points in it can be represented by barycentric coordinate system with space affine transform.

给定空间不共面的四个有序数据点，可以形成一个四面体。

This method represents the virtual objects in Euclidean space instead of in affine space, which is consistent with the popular graphics rendering tools such as OpenGL and is more common in practice. A new classification based local and global tracking strategy to match features between the reference image and the currently frame directly is presented, which enables the augmented reality system working effectively even under large changes of viewing angles. A novel affine coordinate system definition method based on a collection of feature points is also proposed, which makes the tracking method effective even when not all the reference points are detected during the whole process, as long as there are at least four pairs of reference points correspondences.

该方法以仿射变换为桥梁来建立欧氏空间下的摄像机坐标系与世界坐标系之间的变换关系，它与OpenGL等当前流行的图形渲染工具一致，具有更强的通用性；采用基于分类的自然特征匹配策略，能够在视角和视点发生大幅度变化情况下依然正常工作；提出基于特征点集合的仿射坐标系定义方法，使增强现实系统在最小配置下只需4点追踪成功即可完成注册，比需要6点的透视投影方法具有更好的健壮性和精确性。

This project uses natural elements such as wood, bamboo, rock, and sand as the main materials for creation. Technical materials and concepts rich in natural qualities are also used. Artworks are exhibited in the natural environment and public space around the Aigrette Down. They engage in a simple but unique dialogue with the natural landscape and elements of public space.

本案将以自然界的木、竹、石、沙子等材料为主要创作材料，或富涵自然质感的科技材质，或观念上的介入等，以鹭鸶草原周边自然环境与公共空间做为展览空间，让作品与单纯却又具有特色的大自然地景及公共空间元素做对话。

Space environment threaten orbited spacecraft' s safe functioning and astronaut' s health, influence greatly communication depended on based-space way, airmanship orientation, military detection, aim identification, weather observation and source exploration and so on by all sorts of function (magnetic storm, solar proton event and so on).

空间环境通过各种效应(如磁暴、太阳质子事件等)对在轨航天器的安全运行及航天员的健康构成了严重的威胁，对依赖于天基手段的通信、导航定位、军事侦察、目标识别、气象观测、资源勘探等等均有重要影响。

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。
