离子轰击镀沉积的铝镀层均可不同程度地为铀提供好的保护效果。

This atom,with 92 electrons spinning about the closely packed and complex nucleus,is the element uranium,which seems to be the most complicated of the natural atoms.

这一有着92个电子围着又密集又复杂的原子核旋转的原子，就是元素铀。它似乎是天然原子中最复杂的原子了。

This atom,with 92 electro i ing about the closely packed and complex nucleus,is the element uranium,which seems to be the most complicated of the natural atoms.

这一有着92个电子围着又密集又复杂的原子核旋转的原子，就是元素铀。它似乎是天然原子中最复杂的原子了。句中with引出的是一个介词复合结构，作定语，修饰atoms。

Green room: Cockscomb addition to uranium and other radioactive; Aloe three of vinyl chloride, hydrogen sulfide, benzene and other organic matter, and absorb dust, bacteria; cactus absorb the infection; aspartic In addition to heavy metal particles; Chlorophytum is very suitable for on raising plants indoors and do not bother Oh!

房间养几盆绿色植物：鸡冠花除铀等放射性；芦荟除三氯乙烯、硫化氢、苯等有机物，并吸收灰尘、细菌；仙人掌吸收病菌；天门冬除重金属微粒；吊兰是非常适合室内养植且不费心的植物哦！

The Associated Press has a story out about recent activity in uranium production from the Colorado Plateau.

美联社报道了最近科罗拉多高原的铀开采。

His first task was to calculate the critical mass of uranium-

他的第一份工作是计算铀-235的临界质量，也就是维持链式核反应所需的质量。

In-vivo neutron and gamma spectra of depleted uranium sphere and vanadium sphere under central D-T neutron source were measured,with a 18 mm×20 mm stilbene crystal detector, at 7,10,13,16,19,22 cm away to the center in 45° direction in depleted-uranium sphrer, and 1.8,4.8,8.3 cm away to the center in the 0° direction in V sphere.

为获得介质内中子能谱及伴生γ能谱的实验数据，在中心D-T中子照射下，用18 mm×20 mm的茋闪烁体探测器，测量了与D+束成45°角的水平方向距球心7、10、13、16、19、22 cm位置处贫化铀球介质内的中子能谱和伴生γ能谱，以及钒球内与D+束成 0°角、距离球心1.8、4.8和8.3 cm处的中子能谱和伴生γ能谱。
