原子能的来源是在原子的核心。不入虎穴,焉得虎子。要讲解放原子能,必须从研究原子核做起。在二十年以前,研究的工作集中在核外的电子,所以二十世纪的初期是电子学立定基础的时期。同时对于原子核亦逐步有重要的发明,就是原子核物理学的始基,但是到十年前还有人说笑话,以为nuclear physics 是unclear physics。 The source of atomic energy is at the core of the atom. Into the tiger, nothing tiger. Speaking of liberating atomic energy, we must start by studying the nucleus. Twenty years ago, research focused on electrons outside the nuclear field, so the early twentieth century was a time when electronics was established. At the same time, the nucleus also gradually has an important invention, that is, the foundations of nuclear physics, but someone joked a decade ago that nuclear physics was unclear physics.
