uranium 235

uranium 235什么意思,uranium 235翻译

基本解释

网络: 铀二三五

例句

• Because uranium-235 is quite rare, making up less than 1% of natural uranium, it has to be enriched until the fuel contains 2-3%.

  由于铀235很稀有，只占天然铀中的不足1%，所以必须提高浓度，让燃料中有2~3%的含量。

• To make an atomic bomb we have to use uranium 235, in which all the atoms are available for fission.

  制造原子弹，我们必须用铀235，因为铀的所有原子都会裂变。

• To make an atom bomb we have to use uranium 235, in which all the atoms are available FOR fission.

  制造原子弹必须用铀235，因为它的所有原子都可以裂变。

• To make fuel for electricity-generating reactors, uranium is enriched to less than 5 percent of the isotope U-235.

  为将燃料做成电能反应堆，铀被浓缩至U-235同位素含量5%以下。

• And the energy density of uranium 235 in terms of thousand times the energy density of coal.

  铀235的能量密度，能量密度乘以煤的。

• a uranium isotope with mass number 235; capable of sustaining chain reactions.

  铀的同位素，原子质量数为，能进行持续的连锁反应。

• Nuclear power stations use nuclear fission to generate energy by the reaction of uranium-235 inside a nuclear reactor.

  核电站通过核反应堆里铀-235的反应，发生核裂变从而产生能量。

• So you put in more fuel, more uranium 235, a higher enrichment and you need to balance that excess reactivity in a number of ways.

  所以你放入更多的燃料，更多的铀，一个能咖的浓缩度，你需要平衡，剩余反应性，用很多方法。

• Current light water reactors make relatively inefficient use of nuclear fuel, fissioning only the very rare uranium-235 isotope.

  目前的轻水反应堆对核燃料的使用相对低效。只能裂变出非常少的铀235同位素。

• An atomic bomb uses conventional explosives to slam together two lumps of fissionable material, usually uranium-235 or plutonium-239.

  原子弹利用常规爆炸让铀235和钚239这两块分裂性原料相互撞击。
