This week, IAEA Director General Raphael Grossi said the agency was not able to inspect the production of advanced centrifuges at Iran's Karaj facility because it did not have cameras and other monitoring equipment installed at the site.

本周，国际原子能构总干事拉斐尔·格罗西表示，该构无法视察伊朗卡拉伊设施先进离心产情况，因为那里没有安装摄像头和其他监控设备。

But then in 2006 it restarted its centrifuge programme, ended compliance with the additional protocol and turned a deaf ear to the IAEA's questions about weaponisation.

但到了2006，伊朗重启了其离心项目，不再遵守附加协定书，并对国际原子能构关于核武化质询置若罔闻。

Once you have deposited enough saliva in the blue Benedict's solution, we'll mix it in the centrifuge.

等你们加入了足够口水进蓝色贝内迪克特溶液后我们就将它们放入离心中混合。

And meanwhile, Iran has 12 times the amount of enriched uranium allowed under the deal now, and it's installing more centrifuges to go even faster.

与此同时，伊朗浓缩铀产量是协议所允许12倍，而且伊朗正在安装更多离心，以更快地运转。

It says that since August Iran has installed only four of the centrifuge machines which enrich uranium compared to over 1,800 earlier in the summer.

称8份以来伊朗只安装了4浓缩铀离心，而今夏初却就安装了1800多。

He said Iran's advanced home-made centrifuges have been a bone of contention in last week's talks between the Iranian and European Union (EU) negotiators.

他表示，伊朗自主制造新一代离心是上周核谈主要争议点，这次核谈在伊朗和欧盟谈判人员之间展开。

The UN's nuclear watchdog, the IAEA, says Iran failed to allow its inspectors' access to a centrifuge component manufacturing workshop last week.

联合国核监督构国际原子能构表示，伊朗上周未能允许核查人员进入离心部件制造车间。

Under the agreement, Tehran has promised to cut by more than two thirds the number of centrifuges it uses to enrich uranium.

根据该协议，德黑兰承诺将用于浓缩铀离心数量减少三分之二以上。

On my 12th birthday, I really wanted a titanium centrifuge so, you know, I could separate radioactive isotopes. Of course.

我12岁日时非常想得到一钛金属离心，我就能分离放射性同位素了。当然。

President Hassan Rouhani said Tehran will start injecting uranium gas into more than 1,000 centrifuges at its Fordow nuclear facility.

总统鲁哈尼称德黑兰将开始向一千多离心注入铀气，地点是佛岛核工厂。

Iran has told the International Atomic Energy Agency it intends to install new centrifuges at its nuclear plant in Natanz.

伊朗告诉国际原子能构，本国将在纳坦兹核电站安装新离心。

The team built a 38 foot tall centrifuge that rotated at 3 miles per hour to imitate artificial gravity.

该团队建造了一 38 英尺高离心，以每小时 3 英里速度旋转，从而模拟人工重力。

The Islamic state dropped the last key restriction on the number of centrifuges under the nuclear deal.

伊朗放弃伊核协议中最后一项关键限制，即“对离心数量限制”。

They spin uranium around at super fast speeds, about 1,000 times a second shaking out the stuff you don't want and leaving the powerful stuff you do.

离心以超快速度旋转铀，每秒约 1000 次，筛离出没用东西，留下产物。
