摘要
Using the relativistic Lagrangian expression,we develop a method to derive the equation of motion of the torsion balance in a non-inertial reference frame,which is used to analyze the gravitational experiment in measuring Newton's constant G with the angular acceleration method.Our calculation shows that the Earth's rotation couples with the vibration,which should be considered in the high-accuracy experiments of determining the gravitational constant G.
