The appearance of the Chinese Archetypal Criticism is directly related to the new condition of the literatus at that time, such as the weakening of the realism, and the appearance of a new kind of literature form with the similar aesthetic conceptions to the Archetypal Criticism.

新时期本土文艺观的转变为原型批评进入本土话语体系清除了认识上的隔阂，以往强大的现实主义话语的势危为原型批评的异军突起创造了机会，而本土文学创作中一种与原型批评审美观相近的文学形态的出现，又为原型批评向批评实践的渗透准备了充分条件。

Thus we can assert that the difference between global and local squeezing parameter doesn't vanish is a sufficient criterion for the entanglement.

由这个关系，我们可以得到总体压缩系数与局域压缩系数的差值不为零可以作为子系统间存在纠缠的充分条件。

An impulsive control scheme of the Lur'e system and several theorems on stability of impulsive control systems was presented, these theorems were then used to find the conditions under which the Lur'e system can be stabilized by using impulsive control with varying impulsive intervals. The parameters of Lur'e system and impulsive control law are given, a theory of impulsive synchronization of two Lur'e system is also presented.

The major contributions of this thesis include:(1) proposing a new kind of optimal feedback control, followed by its application to chaos targeting and stabilization of high period unstable periodic orbits ;(2) stabilization of unstable fixed point in chaotic systems using some kind of nonlinear feedback control, and giving sufficient condition for the existence of the controller as well as the synthesis procedure;(3) analyzing the robustness of optimal control in chaotic Lur'e systems under the help of H〓 control theory;(4) finally and most importantly, introducing a novel method of information storage based on discrete time chaotic systems as the application of chaos control, and systematically studying different schemata for implementation, providing a theoretic basis for the design of such new kind of information storage devices with large capacity.

本文的主要工作包括，提出一种新的最优反馈控制，并将之应用于混沌引导控制及混沌系统高周期不稳定周期轨道的镇定控制；针对不动点镇定控制的一类非线性反馈控制器，文中给出该类反馈控制存在的充分条件及设计步骤；文中还利用非线性H〓鲁棒控制理论对Lur'e混沌系统中的最优线性反馈控制进行鲁棒性分析；最后，也是最重要的，作为混沌控制的应用，文中提出一种基于离散时间混沌系统的信息存储方法，系统地分析、研究了实现这种信息存储的不同方案，为以后进行这种新型大容量存储器设计提供了一定的理论依据。

Basing on this, this article deeply analyzes the relations between implication and the connective "If, then" used in ordinary logical thinking, and points out that material implication is scientific abstract generation to the ordinary language "If, then". Their sameness lies in: when a conditionals protasis is true and its consequent is false, material implication equation is false.

在此基础上，论文深入地分析了蕴涵与人们极易混淆的日常逻辑思维中的"如果，则"的关系，指出实质蕴涵作为数理逻辑中对日常语言"如果，则"的科学抽象地概括，二者的相同点在于：当前件真后件假时，充分条件假言判断为假，实质蕴涵式也为假。
