事实早在1916 年就已被证明了。

Firstly,I deduce the basic social structure of folk village from the graduallyhappening folk activity in this village.Secondly,I enucleate the"deeply description"on this village folk village acted on the factual movement in family and village.AT last,I point out the basic relationship between folk activity and market economy,betweenthe village and the state.

先是从喜庆活动在村庄中不断发生，推演到喜庆村庄的基本社会结构；然后又从家庭与村庄在喜庆活动中的实际运行过程说明了喜庆活动对于村庄的"深度描写"，最后指明了喜庆活动与市场经济，村庄与国家的基本关系。

Through the statistical analysis and epagoge of the questionnaire on the income satisfaction degree between Shanghai and HeNan province, and by using the measurable income degree to replace subjective eudemonia in order that the eudemonia degree can be caculated and compared accurately instead of just subjective explanation, this thesis finds out the relation features between income satisfaction degree and marriage of urban citizens represented by Shanghai and that of rural citizens represented by Anyang and Xinyang, HeNan Province.

通过对2007年10月上海与河南收入满足度调查问卷数据进行统计分析和归纳，并用可以计量的收入满足度来代替主观幸福感，使幸福程度可以用精确的数量来计算和比较，而不仅仅是主观化的说明，从而得出以上海为代表的城市居民收入满足度与婚姻之间关系的特点及以河南安阳与信阳为代表的农村居民收入满足度与婚姻之间关系的特点，并分析出我国现阶段收入满足度与婚姻关系中城乡之间的相同之处及差异之处：已婚人士的平均收入满足度明显高于未婚人士的平均收入满足度；在已婚人士中，男性相比女性，具有更高的平均收入满足度，说明了男士从婚姻中获得了更多的幸福因素。

It is proved that a left R-module P is pure projective if and only if for any pure epimorphism E→M→0, where E is pure injective, Hom→Hom→0 is exact.

证明了左R-模P是纯投射的当且仅当对任意纯满射E→M→0，其中E是纯内射的，Hom→Hom→0是正合的。

We therefore test if a floating-point variable is zero by testing if it's leass than EPSILON.

下面的函数说明了怎样的EPSILON比如果两个浮点用来测试两个值相等

This graph of data from multiple telescopes shows the distribution of light from a pair of stars known as Epsilon Aurigae.

由多个望远镜的观测数据组成的曲线图说明了柱一双星系统的光度分布情形。

Firstly, based on the stability criterion for the nominal discrete singular time-delay system, a sufficient condition for the existence of the static output feedback controller in terms of linear matrix inequality with linear matrix equality constraint is established, which ensures that the resulting closed-loop system is regular, causal and robustly asymptotically stable, and the static output feedback controller is designed by the feasible solution of the linear matrix inequality with linear matrix equality constraint.

首先基于标称离散广义时滞系统的稳定条件，以受限线性矩阵不等式形式，得到闭环离散广义时滞系统正则、因果且渐近稳定的充分条件，同时利用受限矩阵不等式的可行解给出静态输出反馈控制器的设计方法；然后采用矩阵的正交补，把求受限线性矩阵不等式的可行解问题转化为求严格线性矩阵不等式的可行解；最后的数值实例说明了所给方法的有效性和正确性。

Consisting of 3 Chapters, the Paper mainly includes the following contents: Chapter 1 of Introduct on presents the significance of extending uniform boundedness principle and elso reviews one hundred years development of uniform boundedness principle iind the work done by people in this aspect; Chapter 2 mainly introduce some preparatory knowledge including definitions of dissecting operators, absorbing operators, equicontinuity and some relative examples; In Chapter 3, We discuss the new researching results of equicontinuity principle,uniform boundedness principle and Banach-Steinhaus type theorem .

本文共分三章，主要内容如下：在第一章绪论中说明了推广一致有界原理的意义；回顾了已知一致有界原理一百多年来的发展及人们在此方面所做的工作。在第二章中主要介绍了一些预备知识，其中包括：解剖算子、吸收算子、等度连续的定义并举了一些相关的例子。

The complementary variational principles are extened to two-medium region problems. The equivalence between variational problem and boundary value problem is proved.

将互补变分原理推广到包含两个区域的问题中，从数学上证明了变分问题与边值问题的等价性。

The acquisition of Su-27, after China had attempted for years to develop the J-10 aircraft with equivalent technology to perform similar functions, demonstrates a lack of confidence in domestic industrial capabilities.

在中国研究J-10数年后装备了与J-10相当功能的Su-27，这说明了中国在大型的工业上还是缺乏信心。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
