During the absorption process, each alpha particle will collide with one or more atoms in the conductor knocking electrons from their orbits and imparting some kinetic energy to the electrons in the conductor thereby increasing its conductivity.

" "在吸收过程，每个α粒子碰撞将与一个或多个原子在导体敲开电子从它们的轨道，并传授了一些动能，以电子在导体从而增加其导电性。

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。

The track structure of low electron, proton and alpha particle in water as a media has been calculated with Monte Carlo method. The spectrum of DNA damages has been simulated by the track structure model. Then the surviving fraction at different dose level is calculated by connecting track structure and phenomenological dynamic model.

在理论方面，对电子、质子和α粒子在水中的径迹结构进行了系统地研究与计算，还编制了我们自己的质子的蒙特卡罗模拟程序；用径迹结构模型计算出电离谱并与动力学模型相联系，计算出有实用价值的成活率。

The particles expelled when the atom explodes are protons, alpha rays or neutrons.

原子爆炸时排出的粒子是质子、a射线或中子。

The batch reactor often used to investigate the kinetics of crystal growth on seeded precipitation of sodium aluminate solution .

在铝酸钠溶液的种分过程中，往往利用间歇式反应器来研究晶体的长大动力学，由于受实验过程条件的变化及成核和小粒子附聚的影响，实验结果往往不令人满意。
