The construction tree of set partitions is trans-formed into the number tree and the block tree, and therefore the Pand the...

本文把划分向量V当成一种特殊的数制，找出其进位规则，从而求得V/D和D/V数制转换。所建立的算法经计算机验证，是正确的。

It identifies those communities by way of the multidimensional eigenvectors of network's connection matrices, and then the effects of key parameters on the division results are analyzed through simulation so as to determine the parametrical values which make sure that the results of division are optimum.

利用网络连接矩阵的多维特征向量划分网络社团，通过仿真实验分析关键参数对划分效果的影响，从而确定使得划分结果最优的参量值，并综合多维特征量阈值和社团数目两方面的因素决定被划分的社团数目。

By using the methods of complex representation of quaternion matrices and companion vector, we study and simplify the numerical calculation methods of quaterinon matrices, and establish new aigebraic methods in quaternionic quantum mechanics.

我们通过四元数的复表示和友向量方法，研究并解决了四元数矩阵的一系列数值计算问题，给出一套四元数量子力学中的数值计算方法。

It can not only refect the semantic information of the document, but also keep the characteristics of the document in the vector, what is pay to infrared processing.

试验结果表明，改进后的向量空间模型显著的提高了文档自动分类的准确率和召回率，既能完整的体现文档含义，又能加入文档的语义信息，有利于分类的进一步处理。

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.
