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.

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.
