How many years have passed How many times have the walls been brushed Like clothes, and more like skins Testifying for former residents Furnishings get along well with each other Though they are covered with dust They are not in any disorder And still stiffly remember the past The fingers for the piano have been remarried The keys are still disseminating fragrance Love has moved to other eaves Whose face is still shimmering in the album The world map is like a holy saint Holding his ground at a distinct corner While covert walks and windows Will never be able to line out Solitude is accompanying meditation There is not a single book leaf left Friends have come to deliver complaints and wishes And have taken ashtray and flagon Other seasons will descend Smiles will be fresh in the rain And fill the whole half-old vase While covers are inhabiting all the walls There will be mirrors to consume beauty There will be shoulders to lift the brain Behind cleaning milk and vanishing cream There will be face half hidden The age of sail has gone Yet there are new routes to be inaugurated Glass will gain masks Vacant rooms will gestate once again

经过了这么多年墙壁刷了多少遍像衣服，更像皮肤证明以往的住户家具们相处很和睦尽管有灰尘披覆却一点也不见凌乱顽固地记着从前弹琴的手指已改嫁琴键仍飘散着芬芳爱情已在别的屋檐下像册里谁的脸在闪光世界地图像圣徒坚守在显著的一隅隐秘的小路和窗户永远不可能标出孤独与沉思做伴没有留下一页书朋友们来诉苦和祝愿带走了烟缸和酒壶别的季节会来临微笑会鲜艳在雨里插满半旧的花瓶而封面占据着四壁会有镜子消受美貌会有双肩扛着头脑在洗面奶和雪花膏后面会有面孔半隐半现帆的时代已经过去但还有航线要开辟玻璃将得到面具空房也将再孕育

So, in this paper, a circular cavity witha large radius is used to replace the straight boundary of thehalf space, then the half space problem can be changed tothe scattering problem of two circular cavities to the steadyincident P-wave . Having the aid of the mature cylinderfunction theory, the general solutions of the wave functionscan be given, and an infinite linear algebraic equations ofthe unknown coefficients in the wave functions can be gottenwith the boundary conditions and the Fourier complex seriesexpansion technology, the infinite linear algebraic equationscan be approximately solved by the finite trunction withsatisfying some definite precision, at the basis of thissolution of the equation, the variations and the lay-outs ofthe DSCF at the circular cavity boundary vs. the differentincident angles, the different embedded depths of thecircular cavity as well as the different dimensionless wavenumber of the incident P-wave.

为此，本文采用一个半径很大的圆孔来代替半空间的直边界，将该半空间问题转化为一无限大空间中两个圆孔对稳态P波的共同散射问题，借助于成熟的柱函数理论，通过写出问题波函数的一般形式解，利用问题的边界条件，并采用复数傅立叶级数展开技术将其化为一个仅包含问题波函数中未知系数的一无穷线性代数方程组，在满足一定计算精度的前提下，通过有限项截断进行近似求解，进而讨论了圆孔边界处的动应力集中系数随不同入射角、不同的圆孔掩埋深度、入射波的不同无量纲波数以及介质的泊松比变化和分布情况。

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。

In this sense, both Waldron and Fallon reveal themselves to be only half-hearted democrats.

从这个意义上讲，沃尔德伦和法伦展露的自我只是半心半意的民主主义者。

Now cut each chicken breast in half widthways and then slice each half into five or six long thin strips and then slice each of these in half lengthways so you end up with thin slivers of chicken.

现在把鸡胸肉切成两半，然后横向的把每半切成片，再把每片切成五或六条的肉，然后把每条切开两份，所以你完成了鸡瘦条的工序。
