透视的

The techniques of projection center finding and perspective plane determination in 3 D PIV have been investigated profoundly.

对三维PIV中透视投影的视点定位与透视平面的确定技术作了深入的研究，提出了一种确定视点坐标与透视平面的方法，给出了相应的数学关系式，最后通过实验的方法对视点坐标与透视平面的确定技术进行了检验。

In order to recognize the 2D shapes, we proposed a set of perspective invariants of a pair of coplanar conics in this paper, we suggest a perspective invariant representation of general planar curve based on ellipse, and give an algorithm using the invariants and the representation to recognize 2D shapes.

为了实现二维形状的透视投影不变性识别，本文推导出了一种共面二次曲线对的透视投影不变量，提出了一种基于椭圆的平面曲线的透视不变性表示方法，并且给出了用该不变量和不变性表示方法实现二维形状识别的算法。

As I mentioned last year, we hope to have look-through earnings grow about 15% annually.

就像我去年曾经提到的，我希望我们的透视盈余每年都能够成长 15%，在 1990 年我们确实大幅超越这个比率，但 1991 年结果却差很多，我们在吉列的可转换特别股投资已经被赎回，我们将在 4 月 1 日把它们转为普通股投资，虽然这将会使得我们每年的帐面盈余减少 3，500 万，透视盈余也会跟着减少，另外我们在媒体事业的直接与透视盈余也可能下滑，但不论如何，我们每年还是会向大家报告透视盈余的计算结果。

This paper studies the relations between plane projective correspondence and perspective correspondence and present a necessary and sufficient condition that plane projective correspondence become perspective correspondence.

研究二维射影对应与透视对应的关系，给出二维射影对应是透视对应的充要条件，得到二维射影对应可分解若干次透视对应，进而给出二维射影对应的几何意义。

人类在长期的艺术实践和探索中，创造和发明了许多表现空间远近的方法，从形体和空间关系来说，有平面透视、倾斜透视；从观察位置与观察对象之间的关系来说，则有散点透视和焦点

According to the structure of terrane and exploring water result of coal floor disclosed by hydrology drill hole,it is demonstrated that there exists strong relationship among abnormal apparent conductivity, crack in rock stratum and the extent of filled water in crack,an.

应用音频电透视技术，分析了杨村煤矿2702工作面底板30 m和50 m深度界面的探测成果，并与井下水文钻孔揭露的煤层底板岩层结构及探水结果对比研究，发现音频电透视探测的煤层底板综合视电导率高异常与岩层的裂隙性及其充水程度具有很强的关联性；岩层裂隙与含水层连通性良好部位明显显现视电导率高值异常，结果表明，音频电透视探测成果能够综合反映底板岩层的阻水条件。

In Single Point Perspective,the designer can also determinate Vanishing Point anywhere on the horizon with the need of design's expression effect.Determining Vanishing Points on the horizon in two-Point Perspective,designer draws one of Measurings with the need of design's expression effect.The another can be draw by two circular arcs in the vertical.It solute the problem easy and convenience without drawing by experience of Perspective and confirmed by memory of the Perspective Rule.

在一点透视中，确定直线长度距点也可以是设计者根据设计表达效果的需求任意确定；两点透视中确定直线长度的量点，其中一个是设计者根据表达效果的需求任意确定，另一个可以在立面图上用两段圆弧求出，方便、简单，解决了靠透视经验画图，靠记住透视规律验证的草图、效果图的问题。

When representing cubic images, there are more people choose the range of 8 x 8pixel (34.1%, 37.8%) for horizontal projection and one-point perspective, and more people choose the range of 12 x 12pixel (35.4%, 48.8%) for two-point perspective and three-point perspective.

在水平投影与一点透视表现立方体的图像中，较多人选择8像素*8像素的范围（34.1%，37.8%）；在两点透视与三点透视表现立方体的图像中，较多人选择12像素*12像素的范围（35.4%，48.8%），显示出在制作立体图像时，在这些像素范围以上的图形能获得较佳的视认绩效。

As the representative of the second-generation director, Hou Xiaoxian is creative in his treatment of the film preamble, making it the best footnote to a film. This footnote either expresses the dream about harmonious nature, or becomes a plot metaphor with striking meta-narrative feature, or forms a hologram construction of scatter perspective, etc. Li An, a representative of the third-generation directors, once lived in the U.S. and influenced by Hollywood films, attaches great importance to plot and rhythm in his treatment of film preambles, and favors classical narration. All this is clearly manifested in his "father" trilogy. Cai Mingliang, another famous third generation director, sticks to the artistic philosophy of modernism and displays an arbitrary style.

作为第二代导演代表，侯孝贤创造性地处理片头，使之成为影片的最佳注脚：或传达和谐的自然理想，或成为一个情节隐喻而颇具&元叙事&特征，或构建散点透视的全息式结构；第三代导演的李安因置身异域文化，借助好莱坞电影在中产阶级中的优势，对片头进行了一种重情节、重节奏的剪辑处理，积极靠近古典叙事，这在他的&父亲三部曲&中尤为明显；同为第三代导演的蔡明亮执着于现代主义的艺术理念，透露出个人专断的风格。

How to get rid of understanding of people's inherent, narrow, lacking of the views of many aspects and clairvoyance of modern curriculum theory, how to re-explain the value of local curriculum given by new curriculum, how to respond the puzzles and problems in the practices, how to choose scientific and effective ways, in order to make the nice wishes come true, which can be an important part of national curriculum, that is a true subject.

重新诠释&新课程&赋予地方课程的价值，摆脱对地方课程固有的、狭隘的、缺乏多维视野与现代课程理论透视的理解与定位，回应课程开发实践中的困惑与问题，选择科学有效的作为，实现其作为国家课程体系中重要组成部分的美好初衷，是一个颇具现实意义的课题。
