无穷

This thesis is devoted to the problems of integral conditions, center -focus determination and bifurcation of limit cycles at degeneratesingular point and the infinity of planar polynomial differential system.

本文主要研究平面多项式微分系统退化奇点与无穷远点的可积条件以及中心焦点判定与极限环分支，全文由七章组成。

In Chapter 4, we study the center conditions and the bifurcation of limit cycles at a degenerate singular point as well as that at infinity for a quintic polynomial system and prove that the system has 5 limit cycles around the origin and 2 limit cycles around infinity.

在第三章中，我们分别研究了一类三次多项式系统、一类五次多项式系统、一类七次多项式无穷远点的中心条件与极限环分支问题。

The effects of average potential or a point at infinity used as references on the event- related potentials of spatial selective attention to the right and left visual fields were investigated.

翟义然，尧德中，范思陆，敖新宇，陈霖，在平均参考和无穷远点参考情况下，对左右视野空间选择性注意的ERP反应进行了研究。

A convergence acceleration technique based on functional asymptotic expansion and Poisson's summation formula is developed to raise the calculation efficiency of waveguide dyadic Green's functions which are expanded in infinite series.

为此，作者提出"谱展开边界元法"，以求解波导外空间的并矢Green函数；引入边界元法以求解波导壁内折曲缝隙腔的并矢Green函数；并研究了无穷级数的逐级加速收敛变换，以解决波导中Green函数的计算问题。

The infinite-dimensional inference technique was available to precisely approximate the posterior distribution of the noise.

提出一新的非参数贝叶斯推理算法来辨识任意复杂的多模噪声分布，采用无穷维推理技术，能够较为精确地逼近噪声的后验分布。

These Christians were made of "special stuff" and in their lives I saw the power of eternal life and the integrity of the invisible God.

我从这些"特殊材料"构成的基督徒留学生生活中，看到了一种无穷生命的力量，看到了看不见的上帝的属性。

Unprecedented strange thing were occurring in streams:dinosaurs were out of order,women were pratfall,men were out of control...the primitive libido between man and animals was discharged crazily...

在那里从来没有发生过的怪事陆续发生：恐龙失常，女人失态，男人失控……人与动物的原始欲望被无穷释放

Warlike wind and cloud-a stormy or unstable situation, irregular change is boundless, to the war preceptorial raised very tall requirement.

梗概： 战争风云，变幻无穷，对战争的指导者提出了很高的要求。

It is a continuation of the events left untold in Assassins Creed, its prequel.

这是一个持续的事件留在刺客信条，它的前传无穷。

Our main results are as follows: There are infinitely many positive odd integers not of the sum of two powers of 2 and a prime power.

其主要工作如下：(1)证明了存在无穷多个正奇数不能表成两个2的幂次与一个素数幂次的和。

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。
