用源汇模拟同位素分离气体离心机流场的供取料驱动和机械驱动是离心机流场计算中的方法之一。
The sources and sinks are used to simulate the mechanical drives and the drives of the feed and withdrawals in the simulation of the flow field of a gas centrifuge for isotope separation.
伊斯法罕的铀转化设施，是生产六氟化铀(UF 6，一种铀化合物转化为气体，进入离心机进行浓缩)的装置，在地表以上易于攻击。
The Isfahan conversion plant, which produces uranium hexafluoride (UF6, the uranium compound that is passed as a gas into the centrifuges to be enriched), is above ground and vulnerable to attack.
但这并不排除一小部分此种气体被移作他用的可能性，即取走一些经过计算不超过误差范围的气体用于测试隐匿的离心机。
But that does not rule out the possibility that a small quantity of the gas, calculated to fall within that error margin, was diverted to test some hidden centrifuges.
