Abstract： In this papel, the property of variance of period of the torsional pendulum with appto-ximate linear elastic coefficient in damped vibration is analysed theoretically. The results corresponding to experiment are obteined. Several methods used to reduce variance of the period and to improve measurement precision are developed, such as method of eliminating background variance and method of double suspension wires, on which prestressing force is added.
