In this project, we study the theory of higher order differential equations in Banach spaces and related topics. We solve an open problem put forward by two American Mathematicians and two Italian Mathematicians concerning wave equations with generalized Weztzell boundary conditions, introduce an existence family of operators from a Banach space $Y$ to $X$ for the Cauchy problem for higher order differential equations in a Banach space $X$, establish a sufficient and necessary condition ensuring $ACP_n$ possesses an exponentially bounded existence family, as well as some basic results in a quite general setting about the existence and continuous dependence on initial data of the solutions of $ACP_n$ and $IACP_n$. We set up quite a few multiplicative and additive perturbation theorems for existence families governing a wide class of higher order differential equations, regularized cosine operator families, regularized semigroups, and solution operators of Volterra integral equations, obtain classical and strict solutions having optimal regularity for the inhomogeneous nonautonomous heat equations with generalized Wentzell boundary conditions, gain novel existence and uniqueness theorems,which extend essentially the existing results, for mild and classical solutions of nonlocal Cauchy problems for semilinear evolution equations, present a new theorem with regard to the boundary feedback stabilization of a hybrid system composed of a viscoelastic thin plate with one part of its edge clamped and the rest-free part attached to a visocelastic rigid body. Also we obtain many other research results.

在本研究中，我们对Banach空间中的高阶算子微分方程的理论以及相关理论进行了深入研究，解决了由美国和意大利的四位数学家联合提出的一个关于广义Wentzell边界条件下的波动方程适定性的公开问题，恰当地定义了Banach空间中的高阶算子微分方程Cauchy问题的算子存在族及唯一族，建立了齐次和非齐次高阶算子微分方程Cauchy问题适定性的判别定理，获得了关于高阶退化算子微分方程的算子存在族、正则余弦算子族、正则算子半群、Volterra积分方程解算子族的乘积扰动和混合扰动定理，得到了关于以依赖于时间的二阶微分算子为系数的一大类非自治热方程非齐次情形下的时变广义Wentzell动力边值问题的古典解、严格解的最大正则性结果，获得了半线性发展方程非局部Cauchy问题广义解和经典解存在唯一的判别条件，从实质上推广了现有的相关结果；得到了一部分边缘固定而另一部分附在一粘弹性刚体上的薄板构成的混合粘弹性系统的边界反馈稳定化的新稳定化定理，还建立了一系列其他研究结果。

By using properties of quasi-regular semigroups and left central idempotents, some statements are proved. Let S be a quasi-right semigroup, then (1) S is a quasi-completely regular semigroup;(2) RegS is a completely regular semigroup;(3) R(superscript *) is the smallest semilattice congruence on S;(4) Each R-class T(subscript α) on RegS is a right group;(5) T(subscript α)G(subscript α)×E(subscript α), where G(subscript α) is a group, E(subscript α) is a right zero semigroup.

利用拟正则半群和左中心幂等元的性质，证明了S为拟右半群时，(1) S为拟完全正则半群；(2) RegS为完全正则半群；(3) R为S上的最小半格同余；(4) RegS上的每个R-类T为右群；(5) TG×E，其中G为群，E为右零半群。

In another set of works of the same series《Chairman》, Mao's statue on a pedestal assumes exactly the same waving posture. This posture is a classic image of Mao in the Nation's visual memory - as though he still stood on the Tiananmen Tower, proclaiming the establishment of People's Republic of China, or receiving thousands of red guards during the Cultural Revolution. But the artist tries to plot a difference in this iconic gesture. Mao's palm is painted in the shape of a hand gun. By doing so, he also instils a sense of violence in a solemn and imposing spiritual symbol. The replaced gesture evokes different kinds of historical memories - memories of civil war, memories of class struggles, as well as memories of total destruction.

他那挥手的姿态已经在有意无意之间模拟了领袖的举动；在这个系列的另一组作品《主席》之中，站立在雕像基座上的毛泽东正是一个挥手致意的姿态，这个姿态可以说是他留给整个中国的经典性的视觉记忆，仿佛他仍然站在天安门城楼上宣告中华人民共和国的成立，或者在文化大革命期间接见着从各地赶来的红卫兵们，而画家在这个手势中找茬，他将毛的手掌换成了一个手枪的样式，某种安详、伟大的精神象征被暴力感替换了，这个手势唤起的是另一种历史的记忆：内战的记忆，阶级斗争的记忆，打倒与毁灭一切的记忆。

In a pluralistic, democratic society where a small elite is parasitizing on a middle class segment that has got no idea what to do except to keep working and play along with the rules, a poor underclass that has got no future, and a confused national identity with a history of a multicultural melting pot that sooner or later is about to explode, there is no easy way to solve problems.

在一个多元民主的社会，那里的一小精英，是寄生于一个中产阶级部分已得到根本不知道该怎么办，除了要不断加大工作和发挥随着规则的，一个贫穷的下层阶级已经得到无前途，并混淆国家认同与历史上的一个多元文化的大熔炉，迟早是要爆炸，有没有简单的方法来解决问题。

Modeling and stability analysis problem of linear switched system are emphasized in this part and main results include:(1) Through investigation in the projection of 〓 on x, where x denotes continuous state vector, a series of sufficient conditions for stability, asymptotic stability and unstability of linear switched system's equilibrium in the sense of Lyapunov are achieved. And also, a sufficient and necessary condition for state bounded stability of linear switched system is received.(2) For a class of periodical linear switched system whose switching sets are a group of ordinal lines starting from the original point, it's proved that state bounded stability can be defined by the running characteristic in a single period (3) Based on linear switched system, the concept of linear switched system network is put forward. Linear switched system network is a complex network interconnected by many linear switched systems.

这部分着重研究线性切换系统的建模与稳定性分析问题，主要成果包括：（1）通过考察〓在x上的投影，得到线性切换系统的平衡点在Lyapunov意义下稳定、渐近稳定及不稳定的一系列充分条件，并得到了线性切换系统状态有界稳定的一个充要条件；（2）证明了对于一类切换集为从原点出发的一组射线的周期线性切换系统，其状态有界稳定可根据一个周期内的系统运行特性来判定；（3）在线性切换系统的基础上提出了线性切换系统网络的概念，线性切换系统网络是由多个线性切换系统交互作用而形成的复杂网络。

TWO young black men carjack a white woman's expensive SUV; a white, working-class police officer gropes a rich black woman while her husband, a black Hollywood executive, looks on in impotent rage; a Latina police detective and a Korean woman hurl racial insults at each other after a minor traffic accident; an Iranian shopkeeper sets off to kill a Latino locksmith who he assumes has cheated him.

两个年轻黑人抢走了一位白人妇女昂贵的SUV；一个工人阶级的白人警察在搜查时在一位有钱黑人妇女身上摸来摸去，而他的丈夫—-一位好莱坞的导演只能在一旁眼睁睁的看着事情发生，愤怒却又无能为力；一场小小的交通事故后一位拉丁裔的女警探与一位韩国妇女相互种族攻击；一位伊朗的小店老板因为觉得一位拉丁裔的锁匠欺骗了他于是就想去杀死他报复。

It was a Sunday afternoon, I was window homework, I suddenly saw the big cocks and small cocks actually playing up: big cock, small cock crest directed at a peck, but a small cock leisurely side of the head , no other large cock his head to go back, it will ramp lips a peck, just peck at the eyes on the big cock, big cock, cried, launching the anger, a pair of swollen eyes watching a small cock, small cock also milli do not show weakness, neck Yishenyishen's ready for battle, suddenly big cock sky dive jump out sharp claws, small cock was throwing herself to the ground, big cock, taking advantage of this time back down the small cock small cock look at the neck, blood from small rooster's neck and upper class down, I was taken aback, was about to help it in the past.

那是一个星期天的下午，我正在窗前做作业，忽然看见大公鸡和小公鸡竟打了起来：大公鸡冲着小公鸡的冠子一啄，可是小公鸡不慌不忙的把头一侧，还没等大公鸡把头收回去，它就斜着嘴一啄，正好啄在了大公鸡眼睛上，大公鸡叫了一声，发起怒来，一双红肿的眼睛注视着小公鸡，小公鸡也毫不示弱，脖子一伸一伸的做好战斗准备，突然大公鸡腾空而起伸出锋利的爪子纵身一跳，小公鸡被扑到了地上，大公鸡趁这时压在小公鸡的背上了小公鸡的脖子一下，血从小公鸡的脖子上流了下来，我吃了一惊，刚想过去帮它。

Except that, in lieu of a single monarch and a fluctuating body of favourites and employ, there was a numerous and in a considerable degree fixed class of great landholders; exhibiting far less splendour, because individually disposing of a much smaller surplus produce, and for a long time expending the chief part of it in maintaining the body of retainers whom the warlike habits of society, and the little protection afforded by government, rendered indispensable to their safety.

不过亚洲各国只有一个君主和一大群宦海沉浮的宠臣和官吏，而欧洲则有一个人数众多和相当稳定的大土地所有者阶级，后者远不及前者穷奢极欲，因为他们就个人来说拥有的剩余产品要少得多，而且在很长一段时间内还要用大部分剩余产品供养他们的家臣。由于社会的好战习俗以及政府无力给予保护，当时大土地所有者为了自身的安全必须豢养一批家臣。

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。
