不重要

Two significant drawbacks exist in the empirical methods in practice. First, predictions of excavation-induced wall deflection, ground surface settlement and lateral movement using empirical methods are not very accurate. Second, not all essential factors are considered in the criteria to evaluate the damage of building induced by excavation.

目前工程界惯用的评估方法主要有两个缺点：第一是评估开挖引致变形行为的准确性不高，包括壁体变形及地盘垂直和水平变形；第二是建筑物受损的评估准则没有考虑重要的影响因素，导致评估的准确性不高。

Studies have shown that social grooming is so important to rats that baby rats raised by a mother that does not lick and groom them grow up to be unfriendly and less intelligent than rats raised by a mother who is attentive.

研究表明，社会疏导是非常重要的实验中，婴儿大鼠提出的一个母亲，不舔和新郎他们长大后是不友好和智能不足比提出的大鼠的母亲是谁周到。

It thrills with its light-footed agility. It impresses with its graceful presence. It performs better than ever before, and it work longer than ever before. Inside, the typical cup bottom has been swept aside, and in its place is an elegance and ergonomic harmony that will forever change the way we drink. Welcome the tea set for the new millennium. Please come in.

分酒装置的最重要的概念就是让使用者体会到倒酒这个过程中充满的乐趣，于是我们提出：要让使用者觉得倒酒的过程和品酒过程一样美妙，让产品看起来不是一个复杂的装饰品，也不是一个简单的图形，或者可能看起来更酷的外观。

Certainly some important traits are partly inherited, such as physical size and particular measures of intelligence, but those influence what a person doesn't do more than what he does; a five-footer will never be an NFL lineman, and a seven-footer will never be an Olympic gymnast.

当然，一些重要的特征还是部分来自于遗传的，例如身体形态和一些特异的能力，但是这些影响没有比他们自己对自己的影响大；一个五英尺高的人绝对不会成为国家足球队的前锋的，一个七英尺高的人绝对不会成为奥运体操冠军的。

We must not lose sight of the fact that there are advantages to …….

我们不应当不注意到……有这样的优点。更重要的是，……是不可替代的。

She is not my friend, not my lover either, but the most important person in my life.

她不是我的朋友，也不是我的恋人，是我最重要的人！

She is not my friend , is also not my lover , is my most important person!

她不是我的朋友，也不是我的恋人，是我最重要的人！

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。

The both losing their marriage will produce a regulation on malposition, and lead to a regulation failure finally.

在市场结构动态的变化过程中，如果政府规制政策不做相应的修正，将会出现市场结构与政府规制不对称状态造成的规制错位，即市场结构动态性成为规制错位的重要因素。

They do not represent many other important system quality attributes such as modifiability, buildability, security, reliability, and performance, nor do they represent non-operational or business-oriented qualities such as the ability to reduce development and maintenance costs.

他们不代表许多其它重要系统质量属性譬如modifiability 、buildability 、安全、可靠性，和表现，亦不他们代表non-operational 或朝向商业的质量譬如能力减少发展和维修费用。
