该文研究了一类压缩型映射，得到其不动点的存在唯一性定理。

And the radius of the convergence set of the differentiated series is the same as for the orginal series.

定理5 如果幂级数的收敛半径为则其调和函数在内可导，且有逐项求导公式

In Chaper 4,we extendthe simple Newton's method to sovle our problems,the convergence theorem is proved.

在第四章，我们将简单Newton方法加以推广，用于求解取值在闭凸锥中的非线性包含问题，建立了一般的收敛性定理。

The third chapter mainly verify the weak convergence and strong convergence theorem ofRTRL.

第三章我们主要论证了RTRL算法的弱收敛和强收敛性定理。

Stability and convergence of the model are proven by means of the weak convergence theorem of generalized function and the convolved integration theory.

关于紧算子级数与〓定理，首先给出了序列完备局部凸空间中无条件收敛级数的一个特征。

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。
