ADJ denoting or relating to elements of high atomic number (above 109) postulated to exist with special stability as a consequence of the shell model of the nucleus 超重元素(的) [physics]
Such superheavy elements are usually very radioactive and decay away almost instantly.
这种超重元素通常是具有非常强的放射性，并且几乎立即会发生衰变。
In this paper, the possibility of producing superheavy fragments through composite system breaking up in massive nuclear reactions is investigated.
讨论了通过重核碰撞形成的复合体系破裂产生超重核的问题。
But many researchers think it is possible that even heavier elements may occupy an “island of stability” in which superheavy atoms stick around for a while.
但是，许多研究人员认为甚至更重的元素也可能占据一个可以让超重原子坚持了一段时间“稳定岛”。
