物体自由下落与万有引力常数

在理论上证明惯性质量会产生万有引力，并在万有引力与距离平方成反比的基础上，讨论了不同质量密度的物体在引力场中自由下落加速度的问题。进一步从理论上提供检验不同质量密度的物体之间的引力常数是不同的实验方法。证明了引力相互作用与强相互作用是同一种相互作用。

The Free Falling of Bodies and the Constant of Universal Gravitation

On the basis of a previous work which has proved that the inertial mass can produce gravity, and the magnitude of which is inversely proportional to the square of the distance of the two bodies, it is discussed that whether bodies with different densities fall with the same acceleration. A new method is provided to measure the gravitational constant G that depends on the density of the body. It is proved that the gravitational interaction and strong interaction belong to the same kind of interaction.
