铀

Inside the reactor, uranium atoms are split which release energy and a fast moving neutron.

在反应堆中，铀原子裂变释放能量和快中子。

"Machines that receive their input energy from a natural source (such as air currents, moving water, coal, petroleum, or uranium) and transform it into mechanical energy are known as prime movers ; examples include windmills, waterwheels, turbines, steam engines, and internal-combustion engines."

机械从自然资源(如气流、流水、煤、石油或铀)接收能量，将之变换为机械的能量，此即所谓的原动机，例如风车、水轮、涡轮机、蒸汽机、内燃机。

Uranium distribution in Irtysh River is controlled by human activities.

在表生作用下，铀易活化迁移，而钍则倾向于在残留相中富集。

The contents of U and Th in water samples from the Irtysh River and wastewater from a rare multi-metal mine have been detected directly by ICP-MS.

运用简易、快捷、灵敏的ICP MS法直接测定稀有多金属矿以及河水样品中的铀钍含量，并推算其与比放射性活度之间的定量关系，客观评价了某稀有多金属矿废水中的放射性水平以及额尔齐斯河流域的放射性污染现状。
