摘要
分别详细说明了在牛顿力学中和在狭义相对论中,惯性和惯性质量的概念是如何引入的.明确地阐述了狭义相对论同牛顿力学相类似,物体(可视为质点或粒子)的固有质量(或静止质量)就是其惯性质量.通过分析,指出并强调了运动质量只是个规定,并非物体惯性的大小真的随运动发生了改变.最后还对静止质量为零、速度为光速的粒子只遵从狭义相对论而不可能遵从牛顿力学理论,作了解释.
It is described respectively in detail how the concepts of inertia and inertial mass are introduced in both the Newtonian mechanics and the special relativity.The proper（or rest） mass of a particle has been shown clearly that it is exactly equal to its inertial mass in the special relativity as in the Newtonian mechanics.Through analysis,it is pointed out and emphasized that the relative（or moving） mass is only a prescription but not a results due to that the inertial mass of moving particle has changed really.Finally,the specific property that the particles with zero rest mass and with light speed comply with special relativity but not comply with Newtonian mechanics is explained.
