This research tried to construct the develop track of urban writing of Taiwan new literature from 20's to 30's. On the basis, I resurveyed the previous research on history of Taiwan literature during Japanese period, which is revolved around the traditional countryside and the pauperism. Furthermore, this thesis would reflect the contemporary discourse on colonial modernity under the grand narrative of national perspective, de-colonization, and resistance spirit.
中文摘要本研究试图建构出二、三○年代台湾新文学都市书写的发展脉络;并藉著都市书写的发展脉络重新审视既有以农村、贫民为中心的日治时期台湾文学论述,进而反思当代研究者在国族命运、反殖民、抵抗精神等「大叙述」中过分偏重「殖民性」、现代性反而遭到虚位化、扁平化的「殖民地现代性论述」。

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。

Starting from 3, 5-dihydroxybenzoic acid, a total of 16 kinds of salicylicaldehyde derivatives have been synthesized by the esterification, substitution, reduction, formylation, condensation, brominate, functional group protection and deprotection reactions, of which 11 have not been reported yet. Enatiomerically pure 2-amino-2'-hydroxy-1, 1'-binaphthyl has been easily obtained from its racemic mixture by the eantioselective formation of inclusion crystals with N-benzylcinchoninium chloride.

The third part of this thesis is reactive simulating calculation In this section, some well-known auxiliaries are selected to compute in density functional theory B3LYP on Gaussian 03, from which the relationship between reaction active energies of transition states and enantiomeric excess of chiral products homoallylic alcohols isobtained based on relative reactive ratio theory. Using this relationship, calculations on the reaction of more than eight auxiliaries with four other aldehydes are carried out in AMI and MNDO, proving that N,N\'-dibenzyl tartamide has higher enantioselectivity than others in this reaction.

There are two evident obstacles: first, the object is symbolized and mediumized by ink painting equation, therefore, there is no longer a natural existence for the artists; secondly, the tool nature of brush pen has outshined its nature as ink painting medium, as a result, the ink material effect can only be presented on the precondition of pen moving.
其中两种阻断是十分明显的:一是对象世界为笔墨程式符号化、中介化,画家不再直接面对现场存在的自然;二是毛笔的工具性遮蔽水墨媒材的物性,水墨材质效果的呈现只能以运笔使转为前提。
