惯性质量与引力质量相等的实验验证

设计了一套实验装置,以此研究了物质惯性质量与引力质量的等价性.与以往伽利略自由落体实验和牛顿单摆实验等动态验证法相比,本实验以静态的方式进行,大大减少了机械摩擦和空气阻力,又通过扭秤的光学系统将微弱作用力放大,因而实验的精度可高达,精确地验证了物质惯性质量与引力质量的等价性,填补了国内相关方面研究的空白.

The Experimental Verification of the Equivalence of Inertial Mass and Gravitational Mass

A set of experimental devices is developed to verify the equivalence of inertial mass and gravitational mass.Compared with the classic Galileo＇s free-falling experiment and the simple pendulum experiment carried out by Newton,which were proceeded in motion,the Etvs experiment is carried out in a static state,thus the mechanical friction and air resistance is greatly reduced,in addition the torque on the string can be enlarges obviously by the optical instrument on the torsion balance,therefore,the experiment can reach an accuracy of,which makes the equivalence of inertial mass and gravitational mass accurately verified and fills in a blank spot in this aspect of the domestic research.
