粒子加速器中带电粒子最终速度的计算方法比较

带电粒子在示波器（低速）中和在粒子加速器（高速）中的最终速度的计算方法是不一样的。利用相对论的相关知识推导出粒子加速器中带电粒子最终速度的计算公式，并与在示波器中利用牛顿力学计算的结果进行比较，说明利用牛顿力学的计算式是有局限性的，不适用于高能物理中的相关计算，不能随便假设能量数据进行计算，最后得出设置能量数据时要考虑能量与粒子静止能量的比值W/m0c^2的结论。

How to calculate the final speed of charged particles in the particle accelerators

The charged particles in the oscilloscope （low energy） and in particle accelerators （high energy） in the calculation of the final velocity is not the same. In this paper, the final formula for calculating the speed of the charged particles in particle accelerators is derived with the relative knowledge of the Relativity and the result has been compared with that from Newton＇s mechanics formula,which shows that the later has limitation and does not apply to the high -energy physics calculations, thus we come to the conclusion that the energy data set must consider the ratio of static of the energy and particle energy.
