On the other hand, a lot of methods have been researched and developed in CAGD for computing QSIC in 3D real projective or Euclidean space. The main problem of these methods is the lack of a simple and effective classification of QSIC in 3D real projective space and then lead to their weaknesses on robustness and accuracy.

另一方面，实空间中对QSIC的计算方法在CAGD领域得到了广泛的研究，提出了许多算法，但这些算法对QSIC在实空间的拓扑分类都未能给出简单有效的方法，并因此造成了QSIC几何计算的稳定性和精确性等方面的问题。

The classical work usually assumes the setting of complex projective space in favor of its algebraic closedness; thus the classical results cannot be applied directly to the setting of real projective space assumed in most CAD/CAM applications.

古典的代数几何方法对QSIC的分类在复空间进行，由于复空间的代数封闭性，在复空间对QSIC的分类已有非常完善的结果，但其分类结果不能直接应用于实空间中的CAD／CAM问题中。

This is the content of Brauer's first main theorem for such projective characters and projective blocks.

这一定理包含了经典Brauer第一主定理为其特例(即当α=1时)。

A parametric study graphic nature of the projection, that is, they read the projective transformation, remained the same graphic nature of the geometry, the branches. 2D projective transformation is a more common transform method, used in the camera lens of the camera plane, and applied to various fields of study.

射影几何是研究图形的射影性质，即它们经过射影变换后，依然保持不变的图形性质的几何学分支学科。2D射影变换是一种较为常见的变换方法，发生在用透视摄像机对平面摄像的时候，并应用于各个研究领域。

In the last, The Generalized Hamming Weights of a projective code over was studied by some properties on the projective Variety, and the results of X.W.

在文章的最后我们还利用射影簇上的一些性质，研究了一类射影簇上的码的广义汉明重量。

By taking advantage of a corollary of the Desargues theorem and the corresponging extension of Desarguesian configuration, the concept of stereohomology has been defined in projective geometry and presented based on homogeneous coordinates. Consequently, a series of geometrical transformations, such as central projection, parallel projection, centrosymmetry, translation transformation, reflection, rotation transformation, which can be contained in it or derived from it have also been analytically defined.

利用Desargues定理的一个推论和引申的Desargues图形，给出"空间透射"在射影几何意义下基于齐次坐标表象的解析定义，从而解析定义了可蕴涵其中的中心投影、平行投影、中心对称、平移、反射等几何变换以及可由此衍生出的旋转变换。

Based on projective geometry,a whole set of new stereoscopic3D-PIV theory was established by making use of homogeneous coordinates lineartransform.

文中从射影空间出发，利用笛氏齐次坐标线性变换的方法，建立了一套完整的体视3D-PIV三维重建理论。

A notable merit of parallel coordinates is its well-founded mathematical foundation.Its projective geometrical interpretation and duality properties facilitate the simultaneous projection information representation of multiple low dimension subspaces.

平行坐标的一个显著优点是其具有良好的数学基础，其射影几何解释和对偶特性使它可以很好地同时表达高维数据在多个低维子空间的投影信息。

Also, the inversion is designed in the projective coordinates that will save much computation time.

另外我们采用Projective座标系统，将除法运算转变为乘法运算，进而降低运算结果的时间。

Metrorrhagia is also gynaecological problems of common diseases.

崩漏是妇科常见病也是疑难症。
