The Bohr theory, with its strong flavor of elementary classical mechanics, formed an important bridge between classical physics and present-day atomic theory.

玻尔理论具有强烈的初等古典力学的气味，这就构成了古典物理和近代原子理论间的一座重要的桥梁。

The Bohr theory , with its strong flavor of elementary classical mechanics, formed an import bridge between classical physics and present-day atomic theory .

玻尔理论具有强烈的初等古典力学的气味，这就构成了古典物理和近代原子理论间的一座重要的桥梁。

So said Niels Bohr, one of the founders of quantum mechanics.

现在，我们有了一些能做出进步的希望了。

Germany and the northern countries will hold on to their specialization in mechanics; Britain will be one of the centers of finance and higher education; France will dictate the standard for bon ton and good wines; Italy will remain some kind of open-air amusement park with good food and good weather; and the Iberian Peninsula will continue to be the picturesque European projection to Latin America.

德国和其他北欧国家会继续精于做机器；英国依然是金融和高等教育的中心；法国会在优美语言与好葡萄酒方面独占鳌头；意大利会继续以好吃的和好天气保持其露天大游乐场的地位；伊比利亚半岛会继续成为拉丁美洲心目中的如画般的欧洲。

On the basis of the introduction and analysis of the history, current situation and development of explosive synthesis of superhard materials, the mechanism and technology of diamond and dense boron nitride synthesis by shock compression and some explosive mechanics problem in explosive synthesis have been studied systematically in this research.

本文在对超硬材料爆炸合成研究的历史、现状及发展趋势进行评介、总结与分析的基础上，以金刚石、高密相氮化硼为研究对象，对爆炸合成理论与技术，以及爆炸合成中所涉及的一些爆炸力学理论问题进行了较为系统的研究。其主要研究成果如下

Discover the 3Cr23Ni8Mn3MoN organizes of indoor temperature after passing by the heat temperature , the mechanics function of the heat temperature bottom and the anti-corrosion the function is better than the 4Crl4Nil4W2Mo and 5Cr21Mn9Ni4N.

研究发现3Cr23Ni8Mn3MoN钢经热处理处理后的显微组织、常温及高温下的力学性能和钢的抗燃气腐蚀性能均优于4Cr14Ni14W2Mo及5Cr21Mn9Ni4N钢，能较好地满足排气阀的性能要求。

At one time, we emphasized the solar radiation transfer mechanics. To advance the estimation precision, in this paper, we classed land cover into four layer, canopy of Robinia pseudoacacia L ,top of Melilotus albus Desr,bottome of Melilotus albus Desr and layer of soil, separately estimated their fluxes of moisture, heat and CO2 ,actualized the separated simulation for each composement in soil-vegetation-atmosphere contimuum.

同时，本次研究强调了太阳辐射在冠层间的辐射传输机制，为了提高估算精度，本文把地表覆盖分为刺槐冠层，草木樨上层、草木樨下层及土壤层四个层面来分别估算其水热及CO2通量，做到了土壤-植被-大气连续体能量及物质通量的分离模拟。

Cylindrical boult of flour mill,mechanics model,offsetting poor alignment

中文关键词：面粉机圆筒筛，力学模型，错位配合

This paper takes the cylindrical boult of the 40 flour mills as the object of study,establishes the corresponding mechanics model ,connects theory to reality,designs the nut conicity,then uses the same conicity offsetting poor alignment between the nut and the cylindrical boult,decomposes reinforcingsteel radia.

以40型面粉机圆筒筛为研究对象，建立相应的力学模型，通过理论结合实际，设计螺母锥度，在螺母与圆筒筛之间采用同锥度错位配合，将钢筋的径向受力通过锥面分解到钢筋轴向一部分，使得钢筋在轴向和径向都保持尽可能小地受力。

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。
