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。

The important question is: Does this state of affairs derive from an unavoidable social response to intractable properties in the things themselves, or is it instead a pattern im Philosoph you Tecchnol吆yposed independently by a governing body, ruling class, or some other social or cultural institution to further its own purposes?

重要的问题是：这个事态是源自於一个无可避免的，对事物本身内部难以驾驭的性质的一种社会回应，或者，它反而是被一个支配的主体、统治阶级、或一些在不同社会或文化制度上，为了推动其意图，独自强加其上的模式？

The son of a father to whom history will accord certain attenuating circumstances, but also as worthy of esteem as that father had been of blame; possessing all private virtues and many public virtues; careful of his health, of his fortune, of his person, of his affairs, knowing the value of a minute and not always the value of a year; sober, serene, peaceable, patient; a good man and a good prince; sleeping with his wife, and having in his palace lackeys charged with the duty of showing the conjugal bed to the bourgeois, an ostentation of the regular sleeping-apartment which had become useful after the former illegitimate displays of the elder branch; knowing all the languages of Europe, and, what is more rare, all the languages of all interests, and speaking them; an admirable representative of the "middle class," but outstripping it, and in every way GRE ater than it; possessing excellent sense, while appreciating the blood from which he had sprung, counting most of all on his intrinsic worth, and, on the question of his race, very particular, declaring himself Orleans and not Bourbon; thoroughly the first Prince of the Blood Royal while he was still only a Serene Highness, but a frank bourgeois from the day he became king; diffuse in public, concise in private; reputed, but not proved to be a miser; at bottom, one of those economists who are readily prodigal at their own fancy or duty; lettered, but not very sensitive to letters; a gentleman, but not a chevalier; simple, calm, and strong; adored by his family and his household; a fascinating talker, an undeceived statesman, inwardly cold, dominated by immediate interest, always governing at the shortest range, incapable of rancor and of gratitude, making use without mercy of superiority on mediocrity, clever in getting parliamentary majorities to put in the wrong those mysterious unanimities which mutter dully under thrones; unreserved, sometimes imprudent in his lack of reserve, but with marvellous address in that imprudence; fertile in expedients, in countenances, in masks; making France fear Europe and Europe France!

他的父亲在历史上固然只能得到一个低微的地位，但他本人是值得敬重的，正如他父亲值得受谴责。他有全部私德和好几种公德。他关心自己的健康、自己的前程、自己的安全、自己的事业。他认识一分钟的价值，却不一定认识一年的价值。节俭，宁静，温良，能干，好好先生和好好亲王。和妻子同宿，在他的王宫里有仆从负责引导绅商们去参观他们夫妇的卧榻（在当年嫡系专爱夸耀淫风以后，这种展示严肃家规的作法是有好处的）。他能懂并且能说欧洲的任何种语言，尤其难得的是能懂能说代表各种利益的语言。他是&中等阶级&的可钦佩的代言人，但又超出了它，并且，从所有各方面看，都比它更伟大。他尽管尊重自己的血统，但又聪敏过人，特别重视自身的真实价值，尤其是在宗枝问题上，他宣称自己属于奥尔良系，不属于波旁系；当他还只是个至宁极静亲王殿下的时候，他俨然以直系亲王自居，一旦成了国王陛下，却又是个诚实的平民。在大众面前，不拘形迹，与友朋相处，平易近人；有吝啬的名声，但未经证实；其实，他原不难为自己的豪兴或职责而从事挥霍，但他能勤俭持家。有文学修养，但不大关心文采；为人倜傥而不风流，朴素安详而又坚强。受到家人和族人的爱戴，谈吐娓娓动听，是一个知过能改、内心冷淡、服从目前利益、事必躬亲、不知报怨也不知报德、善于无情地利用庸材来削弱雄才，利用议会中的多数来挫败那些在王权下面隐隐责难的一致意见。爱说真心话，真心话有时说得不谨慎，不谨慎处又有非凡的高明处。善于随机应变，富于面部表情，长于装模作样。

The folk belief governing this practice is that when a new tooth grows in, it will possess the dental qualities, not of the original, lost tooth, but of whatever creature finds it, so the creatures of choice would be those world-class champers, the rodents.

这种习俗依据的民间观念认为，新牙长出来时不具有原先脱落的牙齿的特质，哪种动物发现了掉下来的牙，新牙就具有那种动物的牙的特质。

这种习俗依据的民间观念认为，新牙长出来时不具有原先脱落的牙齿的特质，哪种动物发现了掉下来的牙，新牙就具有那种动物的牙的特质。因此，要选那些世界一流的擅长啃咬的动物，那些啮齿目动物。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
