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。

Has a remarkably wide range, though it is difficult to achieve (the high b makes the first string very taut such that it will break easily), and may not play well on an acoustic guitar (the low C is too low to resonate properly in a standard guitar's body). Luthier Todd Keehn claims to have been the first guitarist to adopt an all-fifths tuning, his being arranged G-D-a-e-b'-f#', and he has made an all fifths tuned guitar that can be seen at his website, http://tkinstruments.com/.

这个调弦的音域相当地宽，但是也很难达到要求（高音B使第一弦崩得非常紧，容易断）这个调弦在原声吉他上的效果也不理想（低音C太低在普通的箱琴上无法产生共鸣）据说Luthier Todd Keehn是第一个用这种调弦的吉他手，他还用 G-D-a-e-b'-f#调弦，他的全五调弦的琴可以在他的网站上看到 http：//tkinstruments.com/。

With her husband, Leonard Woolf, she founded the Hogarth Press and became known as member of the Bloomsbury group of intellectuals, which included economist John Maynard Keynes, biographer Lytton Strachey, novelist E.

与她的丈夫，雷纳 Woolf 在一起，她发现霍迦斯杂志报纸而且变成已知如有知识者的 Bloomsbury 团体的成员了，这包含了经济学者约翰梅纳德 Keynes ，传记作者 Lytton Strachey，小说家 E。

Saign e is sometimes followed by a cold maceration for 3-4 days (up to 12 C or 55 F).

其次是感冒有时saign e浸渍3-4天(最长为12 C或55 六)。

Then, when you type C-c C-e, it takes the code within the region, passes it through the actual C preprocessor, and places the output in a window called *Macroexpansion*.

然后，当你输入C-c C-e，它把选取区域中代码传给一个实际的C预处理器，并把输出结果放到一个叫*Macroexpansion*的窗口里。

So E.T. raised the magic figure of his and gave them a lift

Abstract］ Objective This study investigates accommodative responses to three different kinds of accommodative stimuli (Maltese cross, E visual target and Chinese characters in rapid serial visual presentation) and discusses the differences in accommodative responses when fixation targets and reading tasks were compared.

马耳他十字视标为测量调节反应的经典视标，该视标中央可提供良好的细节，使受试者维持稳定注视，还可通过改变臂长，以获得不同注视距离的相同视角。E视标亦是常用的调节视标，它能够提供较好的细节以及相对稳定的空间频率。

Results When the Maltese cross, E target and Chinese characters in RSVP were presented as accommodative targets, the accommodative responses were (2.07±0.35)D,(2.08±0.30)D and (1.88±0.42)D, respectively.

结果 Maltese cross视标、E视标、RSVP汉字视标作为调节视标，调节反应分别为（2.07±0.35）D、（2.08±0.30）D、（1.88±0.42）D。
