The conditions for ion trapping are studied in the case of uniformly distributed electron bunches and bunch trains in storage rings based on the linear theory.
从线性理论出发，研究了电子束团在储存环里均匀分布和束团串两种情况下离子俘获的条件；

It is proved that in electron circular accelerator, the longitudinal distribution of particles in electronbunch can be approximately expressed as hollow distribution.
在电子环型加速器中可以证明，电子束团中粒子沿纵向的分布律可近似地表示成为空心分布。

We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.
