is introduced. In the new scheme，the moment of inertia of the whole system is changed by changing the distance of
the steel pillars to the instrument rotational axis symmetrically. The variation of moment of inertia is made in a large
range and the symmetrical mass distribution is preserved. So that the relative error is significantly reduced and the
reliability of the verification of the theorem is substantially improved.
