英汉例句
- Aluminium can be transformed,by the capture of an alpha particle and the emission of a proton,into a stable silicon atom.
鋁可以通過俘獲取粒子、排出質子而被蛻變成一種穩定的矽原子。 - Aluminium can be transformed, by the capture of an alpha particle and the emission of a proton, into a stable silicon atom.
鋁可以通過俘獲。 粒子、排出質子而被蛻變成一種穩定的矽原子。 - The nature of the nuclear transformation could be firmly established: the aluminium atom,for example,captures the alpha particle and is transformed,after expelling the proton,into an atom of silicon.
核蛻變的性質因此得到確立。例如，鋁原子俘獲。粒子，竝在排出質子後蛻變成矽原子。 - The nature of the nuclear transformation could be firmly established: the aluminium atom, for example, captures the alpha particle and is transformed, after expelling the proton, into an atom of silicon.
核蛻變的性質因此得到確立。 例如，鋁原子俘獲。 粒子，竝在排出質子後蛻變成矽原子。 - alpha particle ionization detector
