n.名词 U 铀heavy white metal with radioactive properties,a source of atomic energy Noun: a heavy toxic silvery-white radioactive metallic element; occurs in many isotopes; used for nuclear fuels and nuclear weapons源自天王星的名字“Uranus”。1789年,德国化学家克拉普罗特从沥青铀矿中分离出铀,就用1781年新发现的一个行星——天王星命名它,称为uranium。而天王星的名字Uranus来自希腊神话中的天神乌拉诺斯Uranus。uranium dioxide釉的色剂 二氧化…depleted uranium贫化铀natural uranium天然铀highly enriched uranium高浓缩铀uranium hexafluoride六氟化铀uranium enrichment铀浓缩uranium tetrafluoride四氟化铀uranium nitride氮化铀uranium mineral铀矿石uranium fuel铀燃料uranium fission铀核裂变uranium series铀系enriched uranium浓缩铀uranium oxide三氧化铀uranium deposit铀矿床uranium family铀系uranium bar铀棒,铀块uranium trioxide三氧化铀uranium ore铀矿石normal uranium标准铀,天然铀… uran-不|无-ium生化名词⇒n.铀n.化铀元素符号U近义词 U字母U 用作名词n.They went over nation wide in search of uranium mines.他们为了探寻铀矿走遍了全国。Pbisuranium双合铀Pferro-uranium铀铁铀铁合金Ptricyclopentadienyl-iodouranium碘化三茂铀Pbis-cyclooctatetraenyl-uranium双环辛四烯合铀Ptransuraniumn.超铀元素铀后元素a.超铀的铀后的Ptricyclopentadienyl-ethoxyuranium三茂乙氧基铀Ptricyclopentadienyl-octoxyuranium三茂辛氧基铀Ptricyclopentadienyl-methoxyuranium三茂甲氧基铀Ptricyclopentadienyl-isopropoxyuranium三茂异丙氧基铀Ptris-cyclopentadienyl-cyclohexyloxy-uranium三茂环己氧基铀Ptricyclopentadienyl-tetrahydroborato-uranium三茂四氢化硼基铀Ptricyclopentadienyl-chlorouranium氯化三茂铀氯化三环戊二烯基铀Ptricyclopentadienyl-butoxyuranium三茂丁氧铀三环戊二烯基丁氧基铀Ptricyclopentadienyl-cyclohexylisonitrile-uranium三茂环己基异腈铀Ptricyclopentadienyl-cholesteryloxy-uranium三茂胆甾醇氧基铀三环戊二烯基胆甾醇氧基铀Ptricyclopentadienyl-cyclohexyliloxy-uranium三茂环己氧基铀三环己氧基铀三环戊二烯基环己氧基铀
名词100% 用作名词Radium anduraniumare radioactive elements.镭和铀是放射性元素。 A couple of deals have already been cancelled: one for uranium, another for copper and cobalt. 一些合同已经被取消了:一个是关于铀的,另一个是关于铜和钴的。 ecocn And if you keep these neutrons from escaping through leakage they then become available to become absorbed in uranium238. 如果你阻止这些中子通过泄露逃跑,它们之后能够,变成在铀238里能吸收的。163 Another of the authors supplied Marie with the uranium with which she experimented. 而此信另一个作者也曾经提供玛丽试验所用的铀。 yeeyan But there is presumably much more to inspect, including facilities for enriching uranium. 但是据推测还有更多需要检查的地方,包括铀浓缩工厂。 yeeyan Gas reactors require enrichments in the order of up to 20%. So we need to fabricate the uranium into pellets which are clad in zirconium tubes which are placed into the reactor core. 气体反应堆要求充实,以此能,达到20%,所以,我们需要制造出在芯块中的铀,那是锆管道的金属外壳,那被放置入一个反应堆核心里去。163 However, western officials cautioned that there were still many issues to be resolved, about timing and the quantity of uranium involved, as well as guarantees about its handling. 然而,西方官员警告说,仍有许多问题有待解决,如确定与此相关的具体时间、所涉及的铀的数量,以及如何确保其得到恰当的处理。 yeeyan If China is trying to equip every man with a car, then the demand for copper, coal, iron, gold, gas, uranium, which we also have, will be endless. 如果中国试图为每一个人配备一辆汽车,那么对于铜、煤炭、钢铁、黄金、天然气、铀的需求将是无止境的,而这些正是我们拥有的。 yeeyan Niger is the worlds largest exporter of uranium. 尼日尔是世界上最大的铀输出国。 yeeyan Not fission, whereby uranium and plutonium breaks up in pieces, but fusion. 不是裂变,靠那个铀和钚,变成碎片,而是聚变。163 Officials from six world powers have expressed disappointment at Iran's refusal to accept a proposal to send its uranium abroad for further enrichment. 世界六个大国的官员对伊朗拒绝接受将其生产的铀送到国外进一步浓缩的提议表示失望。 iciba The US, Britain, and France want to threaten oil and gas sanctions if Tehran does not suspend the enrichment of uranium, but those threats carry less weight without Russian support. 如果德黑兰不暂停铀浓缩活动,美国、英国和法国则想以石油和天然气制裁来威胁伊朗,但没有俄罗斯的支持,这些威胁的份量将大打折扣。 yeeyan The acids dissolve the uranium, and various other things, leaching them from the ash. 这些酸会把铀以及其他物质溶解,使它们与煤灰分离。 ecocn The fuel was enriched with uranium235 for the nuclear reactor. 核反应堆的燃料被铀235浓缩。《21世纪大英汉词典》 The plutonium preparation had restarted in2003 after an earlier freeze deal, negotiated in1994 with the Clinton administration, had collapsed because of evidence of cheating over uranium. 在一份与克林顿政府1994年签署的协议冻结后,2003年内钸储备又重新开始。 这项储备由于铀欺骗的证据而告终。 ecocn The process releases a lot of energy and more neutrons, which go on to split other uranium atoms, triggering a chain reaction. 这一过程释放出大量能量和更多的中子,于是继续将别的铀原子一分为二,引发连锁反应。 yeeyan Then she found that pitchblende was more radioactive than uranium by itself. 于是她发现沥青油矿,它的放射性要比铀本身还要强。 yeeyan There are tiny amounts of uranium residue in coal; those trace residuals have more energy potential than all the coal itself. 煤炭中有微量的铀残留物;而这些微量残留所蕴含的能量比所有的煤炭本身还要多。 yeeyan There was another example, and that was the famous case of the alleged contract between Iraq and Niger for the import of yellowcake, uranium oxide. 存在这样一个例子,就是那个著名的被宣称的伊拉克和尼泊尔间的冲突,因为“黄饼”-铀氧化物-的进口。 yeeyan These rays are emitted during the decay of certain versions of uranium, iodine, cesium and other elements. 铀、碘、铯和另一些化学元素的某些同位素在衰变过程中会放射出这些射线。 yeeyan This, he says, would squeeze20 times more power out of uranium than current technology does. 他说,这使得从铀中获得的电力比当前技术所产生的多出20倍。 ecocn This is because coal contains trace amounts of uranium and thorium, which are concentrated in the ash. 这是因为煤含有极微量的铀和钍,含量在排放的飞尘中得到提高。 yeeyan Unlike other commodities, uranium itself does not trade on any exchanges. 铀不同于其它商品,它本身并不在任何交易所进行交易。 ecocn We never imagined that there would be uranium in our kids. 我们从来也想不到铀会在我们孩子的体内。 yeeyan Uranium generates gigantic amounts of energy in a very small space, which wind and solar combined cannot come close to. 铀在一块很小的地方就能产生巨大的能量,这是风能和太阳能联合起来也无法比拟的。 yeeyan Uranium is a big factor too. 铀也是一个很大的因素。 ecocn |
