反应堆

SiC ceramic has been extensively applied in precision bearings, sealing element, steam-turbine rotor, burner nozzle, heat interchanger parts, atomic reactor materials and etc. because of its excellent properties in high temperature mechanical properties, antioxidatio, abrasion resistance, thermal stability, smaller coefficient of thermal expansion, larger thermal conductivity, hardness, thermal shock and chemical corrosion.

SiC陶瓷具有优良的高温力学性能，抗氧化性强、耐磨损性好、热稳定性佳、热膨胀系数小、热导率大、硬度高以及抗热震和耐化学腐蚀等优良性能，被广泛应用于精密轴承、密封件、气轮机转子、燃烧喷嘴、热交换器部件及原子热反应堆材料等，并日益受到人们的重视，应用前景十分广阔。

In this paper, the thermal-hydraulic behaviors in the reactor core in hospital neutron irradiator is investigated .

本文对医院中子照射器的反应堆堆芯结构进行了热工水力计算分析。

The established computational method is used in hospital neutron irradiator for different power levels. The detailed fluid velocity and temperature fields in the core and the temperature of the fuel elements are calculated. The maximum power for the onset of the boiling is also predicted.

采用了确定的计算方法对反应堆实际条件下的工况进行了研究，得到了详尽的计算结果，给出了医院中子照射器堆芯的流场和温场，以及燃料元件包壳外表面和内部芯块的温度分布。

After all, the government-owned reactor was fired up in 1957, the same year that the Soviet Union launched Sputnik and Elvis Presley starred in "Jailhouse Rock".

毕竟，这个政府所有的反应堆是在1957年就启用了的，那一年苏联发射了人造地球卫星，猫王主演了《摇滚监狱》。

Physicist Bob Lazar demonstrates his job in Area 51: back engineering an anti-matter reaction motor found in one of the captured flying saucers.

物理学家 Bob Lazar 示范他在 Area 51 的工作：解码其中一只飞碟的反物质飞行反应堆。

The reactor thermal output is 4 250 MW,and average linear power density is 179.5 W/cm.

反应堆热功率输出为4 250 MW，平均线功率密度为179.5 W/cm。

In addition, the preferred separation reactors are provided with mixing looper jets 34 that provide the mixing action for the transesterification reaction.

此外，首选分离反应堆提供混合活套，提供34架的混合行动，酯交换反应。

Thesignals of neutron, temperature, flow and pressure are recorded by multichannelanalog magnetic recorder and are analysed by the dynamical signal analyser ofSD375 type, to obtain auto-power spectrum density, cross-power spectrumdensity, phase shift, coherence and transfer function.

文章叙述了改建的重水研究反应堆(HWRR-3)和高温高压回路的噪声分析。利用多路模拟磁带仪记录中子、温度、流量和压力的信号。这些信号利用SD 375型动态信号分析仪进行分析，求得自动功率谱密度、互功率谱密度、相位、相干和传递函数等。

And they may also try rebuilding their five megawatt reactor and other facilities.

格林说：他们可能逐步采取行动，再加工遗留下来的已用燃料棒，他们还可能重建五兆瓦反应堆和其他设施。

It will have six reactors, be completed in 2014 and have generating capacity of 6000 megawatts.

它有六个反应堆，将于2014年完工，总容量为6000兆瓦。

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。
