The analysis showed that there was more use of verisimilar representations of time in Chinese than in English and this was due to the fact that Chinese language is more iconicity oriented while English is more bounded by gram...

操汉语的人是基于客观真实时间顺序和主观想象时间顺序来构建其句子和概念的，其时间表征多为似真表征方式，英语里虽也有某种程度的似真表征，但说英语的人更多的是依据形态语法和抽象原则来表征时间关系的；时间的隐喻表征在两种语言中既有相同之处也有很大差别，这主要源于不同文化的价值观和认知方式

In their exercise of power, the primary task of modern nation-states is to transform "people" into politically, culturally and volitionally bounded "citizens," so that the state, instead of the "ruler," will be regarded by the ruled as the object of loyalty, and supportive forces that uphold from below the identity of political communities will occur.

现代民族国家的政治权力之遂行，首要工作乃是将「人」打造成有政治边界、文化边界与意志边界的「公民」，以使被统治者政治效忠的对象由「统治者」转变为「国家」，并且产生具有再生产性质由下而上支撑政治共同体同一性的支持力量。

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。
