alpha atom

英 [ˈælfə ˈætəm]

美 [ˈælfə ˈætəm]

【计】α原子

Each emission of an alpha or beta ray accompanies the transmutation of an atom; the energy communicated to these rays comes from inside the atom.
每一次a射线或b射线的放射都伴随着原子的蜕变，因为赋予这些射线的能量来自于原子的内部。
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.
核蜕变的性质因此得到确立。例如，铝原子俘获。粒子，并在排出质子后蜕变成硅原子。
Aluminium can be transformed, by the capture of an alpha particle and the emission of a proton, into a stable silicon atom.
铝可以通过俘获。粒子、排出质子而被蜕变成一种稳定的硅原子。
For Nitro derivatives of methylbenzenes, the pyrolysis initial reaction is an isomerization reaction. It means the alpha C-H bond in methyl rupture, then the Hydrogen atom transfer to the Oxygen atom in nitryl to form isomer.
甲苯的硝基衍生物的热解引发反应为异构化反应&α（C-H）中的C-H键断裂，氢原子转移到邻位硝基（-NO2）中的氧原子上，生成新的异构体化合物。
