不充分

The control objective is achieved by firstly using robust passivity to stabilize the linear subsystem, and then with resort to switching control technique to guarantee the invariance of the specified region in state space simultaneously. Hence, a sufficient condition for the robust invariance switching control of this class of systems is derived.

控制思想是首先通过鲁棒无源性技术来镇定线性子系统，再借助切换控制技术得到系统轨迹对于指定区域的正不变性，从而得到了该类系统鲁棒不变切换控制的充分条件。

Like these are not good in the micro-phenomenon, I believe that the main bodies are available to small and medium investors than a more comprehensive and more fully, so they cover tight purse, has been reluctant to sell, and in this psychological Game, the first to lose patience with the most重仓shareholder.

喜欢这些不是在微观现象的好，我认为主要机构，是提供给中小投资者比更全面，更充分，所以他们盖紧钱包，一直不愿出售，在这种心理游戏，首先失去了最重仓股东耐心。

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。

There seems to be a dilemma: if a manager doesn't have sufficient discretion, her firm cannot act as a "profit maximizer" in markets; if she is given considerable discretion, she may use the discretion to pursue goals other than profit maximization.

国有企业改革的局面看起来似乎已经陷入困境，如果经理没有足够的判断力，其公司在市场中就不能实现"利润最大化"；如果他有充分的分辨力，他才有可能利用其判断力来实现"利润最大化"目标而不是尽可能的获取利润。

Property Law adopted a layered approach of the land using right for building, which is not an effective solution to the multidimensional space demand in the social reality and is not conducive to a full and effective use of the space resources.

物权法》所采用的建设用地使用权分层设立的方式，不能有效解决社会现实中对空间利用的多方位的需求，也不利于形成对空间资源加以充分有效利用的局面。

It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help its passage even when the wind is adverse.

燕子充分兼有这两类鸟的长处，它既不疲劳，也不炫耀自己的飞翔力；在空中十分自如，可以飞行6，000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。

The swallow shares the virtues of both schools in highest measure.

Their number follows ,such as partridges,have a like power of strong propulsion,but sooner tire.you may pick them up in utter exhaustion,if wind over the sea drive them to a long distance.the swallows share the virtues of both schools,it tires not ,nore does it boast of its power.it belong to the air.travelling it may be six thousand miles to and from the northern nesting home.

如果海风驱使它们飞行很长距离，你可以捡到一些因筋疲力尽而摔下来的鹧鸪。燕子充分兼有这两类鸟的长处，它既不疲劳，也不炫耀自己的飞翔力；在空中十分自如，可以飞行6，000英里，可以飞往北方做窝的老家，再从老家飞回；一边飞一边喂养会飞的雏燕，甚至在顶风时也能在气流中滑翔，似乎气流在帮它前进。

To ensure that VolP can reach its full potential and is not stifled by unnecessary or poorly tailored regulation, government should:◆ create a policy framework that encourages the continued development of an IP-enabled service environment;◆ adopt a light regulatory approach that focuses on encouraging competition, and maximizes flexibility for the introduction of VolP services, while respecting the need to ensure consumer protection;◆ ensure that VolP services are open to provision by all interested service providers, and that where licensing conditions exist, they are objective and nondiscriminatory, and the criteria for granting authorizations are transparent

为了确保福尔普可以充分发挥其潜力，而不是扼杀不必要的或定制的监管不善，政府应：◆建立一个政策框架，鼓励一个持续发展 IP的服务环境；◆采用了轻监管模式，重点是鼓励竞争，最大化的福尔普服务的引进灵活性，同时尊重必须确保消费者保护；◆确保福尔普服务是开放给所有有兴趣的服务提供提供商和发牌条件，如果存在，它们是客观的，非歧视性的，并给予许可的标准是透明的

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
