【摘要】 文中设计了天平秤的臂长可以变化的假想实验,在狭义相对论的范围内证明了运动物体的惯性质量和引力质量随速度的变化都遵从关系 m=m₀/（（1-V²/c²）¹/2） 于是,若在静止时物体的惯性质量和引力质量严格相等,则在高速运动时二者仍严格相等。这使得作为广义相对论基本假设之一的等效原理得到更广泛的依据。更多还原

【Abstract】 This work has designed an ideal experiment of balance whose arm length of scales may be varied. Proved that all variations of inertial mass and gravitational mass of mobile objects with velocities obey the relationship in range of special theory of relativity.So that, if inertial mass and gravitational mass of an object are strictly equal at rest condition, then both still equal when the object moves at high velocity. This makes the equivalent principle as the one of basis hypothesis of the general theory of relativity to gain more extensive basis.更多还原
