不动地

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。

"Her cutlets à la Maintenon made mutton seem more than mutton; a sublimated meat that could scarcely have grown upon any mundane sheep," he murmured, sentimentally, and Mrs.

"她那曼因坦侬式羊肉片①，把羊肉做得超过了羊肉，一种升华、美化了的肉，尘世间的哪一只羊身上也长不出这种肉来，"他多愁善感地喃喃自语道，"而马隆尼夫人做的羊排往往是老得咬不动的；不过，人生就是这样的——一个菜肴又有什么大不了呢？"

"No. I'd be too scared to run," Emil admitted mournfully, twisting his fingers.

"不，我吓得跑不动了，"爱弥儿难过地说，一边捻着他的手指头。

Life is a boat. The life boat cannot carry too much appetency and peacockery. You have to light it if you don't want it take the ground or sink down in the halfway before arrives the other shore. To carry things what you really need, and put down the "nuts" decidedly.

生命如舟，生命之舟载不动太多的物欲和虚荣，要想使之在抵达彼岸时不在中途搁浅或沉没，就必须轻载，只取需要的东西，把那些应该放下的"坚果"果断地放下。

I stared at grandpa';s body, which was lying serenely in the ward. I was not able to say a single word.

六、凝望着安详地躺在病房里一动也不动的爷爷，我却一句话也说不出来了。

My human fixture and her satellites rushed to welcome me; exclaiming, tumultuously, they had completely given me up; everybody conjectured that I perished last night; and they were wondering how they must set about the search for my remains.

我那坐在家里不动的管家和她的随从蜂拥而出来欢迎我，七嘴八舌地嚷着说她们都以为我是没指望的了。人人都猜想我昨晚已死掉了。她们不知道该怎么出发去找我的尸体。

Sitting motionless in the still air with the only sound being the slatting of sails and rigging is b-o-r-i-n-g, and, with neither of us being avid conversationalist, we had apparently exhausted our normal subjects.

寂静的空气中，船身一动也不动，唯一听到的声音是帆和绳子噼啪的碰撞声，无聊地令人窒息。我们两个都不健谈，平常的话题快谈光了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
