浓缩铀

But Foreign Ministry spokesman Ramin Mehmanparast said on Tuesday that Iran was not opposed to sending LEU abroad as long as it had "100 percent guarantees" it would receive refined fuel in return, for use in a medical research reactor.

但周二外交部发言人 Ramin Mehmanparast称伊朗不再拒绝把低浓缩铀运至国外，只要&100％保证&它将换回可用于医学研究反应堆的精炼燃料。

Meanwhile,while Iran is moving toward nuclear weapons,some 37 tons of what they called yellow cake,the stuffthey use to make enriched uranium, while they're doing that,North Korea has moved from one bomb maybe,maybe,to four to seven bombs.

与此同时，伊朗却正在研发核武器。他们拥有37吨被他们称之为&黄饼干&的东西，即他们提炼浓缩铀的原料，在伊朗做这件事的时候，朝鲜也许已经制造了一件核武器，也许是四到七件。

Enriching uranium increases the uranium 235 concentration in the material, which increases the amount of fission that occurs in a given amount of uranium.

浓缩铀提高了铀235的浓度，从而增加了一定数量铀中发生的裂变量。

Methods Neonate rats were irradiated with a single injection of 2 μl enriched*" 235 uranium( 235 U)into the lateral ventricle of the rat brain on the first day of life(less than 24 hours after birth)at doses of 0,1,5 and 10 μg of*" 235 U,respectively.

新生大鼠侧脑室注射 2 μl浓缩铀溶液后，多方位地观察不同浓度的2 35U对早期生长发育的影响，放射自显影示踪术观察脑内放射性核素行径定位。

But the fear is that the same centrifuges could be reconfigured to make high-enriched uranium for nuclear weapons.

然而国际害怕的是同样的一个离心器可以通过改装，来生产核武用途的高浓缩铀。
