Research in this area includes alternative energy systems; environmental risk and economic impact assessments; hazardous waste site analysis and remediation planning; electrometallurgical treatment to prepare spent nuclear fuel for disposal; and new technologies for decontaminating and decommissioning aging nuclear reactors.

这一领域的研究，包括可替代能源系统；环境风险和经济影响评估；危险废物现场分析及整治规划； electrometallurgical治疗准备用过的核燃料进行处置；和新技术净化和退役老化核反应堆。

This was the MKRC Legenda space-based system, operational in 1979, the main element of which is radar-equipped 17F16 satellites that use onboard miniature nuclear reactors for power.

这套系统在1979年投入使用，该系统主要由装备雷达的17F16型卫星组成，卫星上有星载微型核反应堆提供电力。

A member of the actinide series of transition elements, it is the most important transuranium element because of its use in certain types of nuclear reactors and in nuclear weapons.

锕系过渡元素及其化合物，是最重要的超铀元素，用作核反应堆燃料和核子武器装料。

Not only is waste disposal a problem, but the cost of decommissioning these plants now appears to be much higher than anticipated. In 1993 the first nuclear plant began to be taken apart for decommissioning.

不仅废弃物的处理是个问题，并且关闭核电站和花费似乎比建立它时高的多，1993年第一个核工厂因关闭核反应堆而被解体。

At a news conference, President Bush reaffirmed Washington's refusal of North Korea's demand for a light-water nuclear reactor before it disarms.

在新闻发布会上，布什再次重申华盛顿拒绝北韩提出的在放弃核武器前得到轻水核反应堆的要求。

But last week, North Korea apparently began reassembling its Yongbyon nuclear reactor, according to U.S.

但据美国官员表示，上周朝鲜明显重启了宁边核反应堆。

France reprocesses its nuclear waste to reduce its mass and make more energy.

法国对核反应堆进行再处理以减少污染和生产更多能源。

Although China's thirst for power has mostly been slaked by coal, the country has also completed some nuclear reactors like this Westinghouse-derived station built by the French company Framatome, now known as Areva.

尽管中国主要还是依靠煤炭提供电力，但也有一些由法国阿海法公司建造的核反应堆。

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。
