不可实现的

For example, we cannot copy an unknown state exactly because of "the no-cloning theorem"(no-deleting theorem), which is known as one of the most significant differences between classical and quantum information. Therefore to get to know what we can and cannot do in QIS or in quantum physics becomes an important and interesting problem. Particularly, in quantum communication and quantum cryptography, many novel schemes are based on the fact that nonorthogonal states cannot be discriminated determinately.

例如，经典信息中，编码状态是可以精确复制、区分的；而在量子信息中，由于叠加性的存在，使得非正交态不可区分，量子态不可复制、删除等；故而以往既成的观念都被打破，探讨在量子信息的框架下编码信息的估计、物理可实现的操作，以及这些量子体系在外界通过物理方法进行识别过程中的差异，是量子信息学、乃至物理学中的重要也很基本的问题。

The paper states that polynomial based interpolators are not optimal, but they can be efficiently implemented using Farrow structure.

指出，全数字极大似然最佳接收机算法中包含非因果操作，是复杂、不可物理实现的，但是它可以作为次最优可实现算法和结构的基础。

The realization of composing interface technology is explained by analyzing the structure,realization,accessing and advantages of PDAPI. Meanwhile,the technology satisfies the integrated restrictions:self-containment,collaboration, unsustainably and recombination.

通过对组件PDAPI的结构、实现、访问的研究和对技术优点的阐述，说明组件接口技术的具体实现，以及对自我包容、沟通协作、复合使用和不可持续的满足。

Finally, by discussing the concept of action, this paper tries to show that people aren't completely decidable. But this undecidability should be comprehended in the context of self-understanding. The author's personal view is that self-understanding is the demonstration of self-realization.

最后将透过对行动概念的讨论，说明人的不可完全决定性，但这个不可决定性必须在人对自我理解意义上来理解，个人以为自我理解就是人的自我实现的具体呈现。

Though there is no unrealizable technical difficulty for FTTH, its success shall highlight the following aspects and integrate efforts to solve the key points: develop new device and kernel control chip adapting to features of FTTH, reduce the cost of optoelectronic devices and passive devices; develop low cost, easy installation indoor optical fiber, cable and linker as well as matching construction equipments and tools; develop high density, easy operation optical fiber distribution frame; and develop concentrated remote monitor, management techniques and systems.

FTTH技术是未来宽带接入的主要模式，从长远来看也是其他技术无法取代的，FTTH虽然没有技术上不可实现的难点，但要使FTTH走向成功，以下方面值得重视并应集中力量攻关：开发适应FTTH特点的新型器件和核心控制芯片，降低光电器件和无源器件的成本；开发低成本、易安装的室内光纤、光缆和连接器及相配合的施工仪器工具；开发高密度、易操作的光纤配线架；开发集中的远程监视和管理技术及系统等（178）。

Human rights are divided into generations:civil and political rights as the first generation and economic and social rights as the second.The former is negative,the latter is positive;states have obligation to the result immediately to the former and only to realize gradually to the latter;the former is judiciable and the latter is not.

在对人权的认识中，公民权利和政治权利与经济、社会权利被人为地做了前后代际分野：前代是消极权利，后代是积极权利；前代是&立即实现&义务或结果义务，后代是&逐渐实现&义务或行动义务；前代是可裁决的，后代是不可裁决的。

In the process of enforcing the law and realizing social justice,legal supervision has an uneligible and unreplaceable function.

在实现法治、实现社会公平正义的过程中，法律监督具有不可忽视、不可替代的功能。

And more it is writer him general the comprehension in the life and dissatisfaction, on affection frustrated, the desire that cannot come true and a variety of affection abreacts in connecting accommodate to sb to enter a novel, produce intense resonance with the reader thereby.

而更多的是作家将自己在生活中的感悟与不满，情感上的失意，不可实现的欲望以及种种的情感发泄通通融进小说中，从而与读者产生激烈的共鸣。

Reading the document made it clear that CCM was technically immature; sections of it were essentially unimplementable or, if they were implementable, did not provide portability.

阅读文档就可以清楚知道 CCM 技术上是不成熟的；部分根本不可实现，即使实现，也无法提供可移植性。

Chapter one states briefly the Adenauer government" European policy" aims and its best way to achievement of these aims.
