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

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.

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.
