摘要
设计了一种新的测量大质量物体间万有引力常数G的实验方案,笔者先阐述了该方案总体设计结构,然后分析了预期的理论观察值.设计分析表明:该方案中被照物投影在接收屏上将会出现3.75 mm的预期位移.最后提出了降低测量误差的方法.
A new experimental scheme to measure the gravitational constant G between big objects is introduced. Firstly, the overall arrangement of the new experimental scheme is presented. Then, the anticipated observation value is analyzed. Finally, the error in the new experimental scheme is analyzed and the method to reduce the error is put forward. Analysis shows that the displacement of small objects＇ shadow on the screen will be 3.75 mm.
