1·A radioactive atom could transmute itself into an entirely different kind of atom.
放射性原子本身能嬗变为性质完全不同的另一种原子。
2·Suppose we've got some sort of radioactive atom, which has a certain chance of decaying.
假定我们有某种放射性原子，它们以一定的几率衰变。
3·The original theory involved putting a hypothetical cat into a theoretical box along with an imagined radioactive atom.
他的理论是把一只假设的猫放到理论上存在的盒子里再扔进去一个想象中的放射性原子。
4·Something even Schrodinger never thought of when he came up with the whole cat in the box with the radioactive atom scenario.
就连薛定谔编出猫跟放射性原子一起关在盒子里的故事的时候，他也没想到有这种神奇的事情吧。
5·The process by which an atom changes from an unstable state to a more stable state by emitting radiation is called radioactive decay or radioactivity.
原子通过辐射由不稳定状态转变为更加稳定状态的过程称为放射性衰变或放射性。
6·The process by which an atom changes from an unstable state to a morestable state by emittingradiation is called radioactive decay or radioactivity.
这种原子通过释放射线从不稳定状态变到更加稳定的状态的过程被称为核衰减或放射。
7·The technique is so sensitive that it can detect a single radioactive carbon atom hiding among a quadrillion (one million billion) ordinary ones.
这项技术非常敏感，甚至能够在十的十五次方（一千万亿）个普通碳原子中找到一个放射性碳原子。
