摘要: 在狭义相对论框架内对质量的物理实质进行了探讨,指出一个物体的静质量是在其质心参照系中该物体总体能量的反映参量,惯性和引力特性仅仅是质量的物理性质的一个侧面.

关键词: 质量, 能量, 相对论变换, 相对论动量

Abstract: Based on the special relativity, the essential meaning of the mass of an object is analysed. It is shown that the mass of an object is a parameter which imply the total energy on the mass centre frame of reference, the inertia and attraction are both the physical characteristics of the mass.

Key words: mass, energy, transformation of relativity, momentum of relativity
