摘要: 依据相对性原理以及相对论动量、能量的基本定义和相应的动量守恒、能量守恒定律,针对静质量不为零的粒子,给出一种无需依赖运动学具体时空变换关系而主要在动力学范围内得到相对论质能关系的新推导.

关键词: 质能关系, 相对论动力学, 洛伦兹变换

Abstract: On the basis of the definitions for relativity momentum and relativity energy, a new derivation of the mas.s-energy relation for massive particles is presented in the relativistic dynamics according to the conservation of both momentum and energy as well as the principle of relativity. The derivation makes no use of the specific space -time transformation.

Key words: mass-energy relation, relativistic dynamics, Lorentz transformlation
