向量子空间

In addition, it's found that abridgment methods are comparative to Vector Subspace Method when the spectral image compression application is considered.

另外，还给出了三阶删节方法与"向量子空间法"在光谱图像压缩方面的特性比较，比较的结果发现，三阶删节方法要比"向量子空间法"更好一些。

In the second chapter, we study a pinching theorem for submanifolds of locally symmetric space with parallel mean curvature .

第二章节是关于局部对称空间中具有平行平均曲率向量子流形的pinching定理，设M是局部对称空间N~中一个紧致子流形。

In the last chapter,we constructa bipartite graph by all 1-dimensional subspaces and all maximal totally isotropicsubspaces of symplectic space,and obtain that this graph is a distance-semiregulargraph,its bipartite half is the complement of symplectic graph.

最后，我们利用辛空间中的所有一维向量子空间及极大全迷向子空间构作了一类二部图，证明了此图是一个距离半正则图，其二部半图是辛图的补图。

The intensity of NP peak of type-Ⅱ initailly increased with the increase of the excitation power and decreased thereafter. This is due to the electrons and the holes were localized in different space of typ-Ⅱ QW, then the band bending occurs when the carrier concentration increases with the power, NP peak shft to high energy. The electron transited to relaxed Si〓Ge〓 layer and combined with the localized holes radiatively.

型量子阱的NP峰随激发功率增加先增加后减小，这是由于在Ⅱ型量子阱中电子和空穴不在空间同一位置，较强激发功率下产生的高浓度载流子引起能带弯曲严重，NP峰向高能方向移动，到某一定程度时开始出现电子跃迁至弛豫Si〓Ge〓层与其中的空穴复合发光。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
