In a circularaccelerator, magnetic fields accelerate particles moving in circular paths.
而在环形加速器内，是靠环形路径上的磁场加速的。

It is proved that in electron circularaccelerator, the longitudinal distribution of particles in electron bunch 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。

The Large Hadron Collider is a 27km-long circularaccelerator that is being built at CERN, the European particle-physics laboratory near Geneva, specifically to look for the Higgs boson.
