查询词典 classical mechanics

Classical electric mechanics confirmed that accelerating charge must eradiate electromagnetic wave, while at the same time, quantum theory confirmed electron accelerates in the same energy-interzone in atom never radiate electromagnetic wave, is it possible to be united in theory?

经典电动力学认为加速运动的电荷能够辐射电磁波，而量子力学指出电子在同一能级内做加速运动不能辐射电磁波，能否把它们统一起来？

Quantum mechanics is such a rain forest of a theory, filled with indescribably weird animals and endlessly explorable backwaters, that seeking to reduce it to classical physics seems like trying to grow the Amazon from a rock garden.

量子力学就像是一座雨林，充满无法形诸笔墨的珍奇动物以及无数有待探索的偏僻水域，要将它归纳入古典物理之中，就好比试图在一座光秃秃的岩石公园中种植出亚马逊森林。

With the increase of the proportion and degree of difficulty of the tunnel project in the whole highway construction, in geotechnical questions, especially with the improvement of big mechanized and automatic construction technology, the new geotechnical questions have appeared , are changed into moving simulation dynamically from the mechanics problem of classical rock, in order to solve these new problem, this paper proposes the studies of the displacement inverse analyses and fuzzily classifies and the surround rock intelligently and predict out of shape greyly.

随着隧道工程在整个公路建设中的比重和难度的增大，在现代岩土工程问题中，特别是随着大机械化和自动化施工技术的提高，出现了新的岩土工程问题，由经典岩石力学问题转变为动态挠动模拟，为了解决这一新问题，本文提出位移反分析模糊分类及围岩变形智能化灰色预测研究。

Quantum key distribution produces and releases key by making use of quantum mechanics principle,to solve the insuperably limitation of key distribution in classical cryptography,and guarantees the absolute security of the cryptographic key.

量子密钥分发系统是利用量子力学的基本原理来产生和发布密钥，以解决经典密码学在密钥分发方面存在的无法克服的缺陷，从而保证密钥在发布过程中的绝对安全，进而实现通信双方所交换信息的绝密。

Quantum mechanics breaks though the mechanical determinism in classical science, transforming it into nonmechanical determinism; it changes scientific cognitive process from the theory of reductionism to the theory of wholism; it shifts the way of thinking from pursuing simplicity to exploring the complexity; it also establishes the interaction between subject and object in scientific researches.

量子力学突破了经典科学的机械决定论，使之转化为非机械决定论；使得科学认识方法由还原论转化为整体论；使得科学思维方式由追求简单性到探索复杂性；确立了科学活动中主客体互动关系。

3 Fatigue strength analysis of WIG structure Combining the classical fatigue S-N curve with the theory of fracture mechanics the fatigue strength of some weak parts of WIG has been calculated.

产生影响的主要是结构的低阶频率，所以今后实验中如何排除弹性支撑刚度对结构低阶固有频率影响是今后实验中需要解决的问题。

His other contributions include relativistic cosmology, capillary action, critical opalescence, classical problems of statistical mechanics and their application to quantum theory, an explanation of the Brownian movement of molecules, atomic transition probabilities, the quantum theory of a monatomic gas, thermal properties of light with low radiation density (which laid the foundation for the photon theory), a theory of radiation including stimulated emission, the conception of a unified field theory, and the geometrization of physics.

的经典问题和它们的量子理论的应用，解释了布朗分子运动，原子跃进概率，单原子气体的量子论，地辐射密度的光的热性质，包括受激发射的放射理论，统一场论的概念和物力几何化。爱因斯坦写了多于50篇的科学著作，也包括非科学的书。1999年爱因斯坦被时代杂志封为&世纪人物&，一份有卓越成就的物理学家的民意测验封他为无论何时都是最伟大的物理学家。现代文化认为&爱因斯坦&和天才是同一个意思。

To getrid of these shortcomings DMs are presented in quantum theorywhere the movement of individual electron is determined byquantum mechanics and the system of electrons obeys Fermi-Dirac statistics,in consequence they can find wider appli-cations than classical DMs.

这里个别电子的运动由量子力学刻画，多电子系遵循Fermi-Dirac统计规律，故它们比前三种经典公式普适性更强。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
