摘　　要：从1982年起至1990年,用高精度扭摆对日月食的引力效应做了六次检验性观测,皆未观察到E.Szxl等人所发现的扭摆周期异常变化现象.本文作者采取多种抗干扰措施并对吊丝进行非线性校正,使扭摆的测量精度提高至9.6×10^(-8),周期变化曲线的最大相对起伏值降低至9.6×10^(-8).To verify the abnormal changes of the period of torsion pendulum during solar and lunar eclipse reported by Dr. E. Saxl et al. in 1964 and 1971, six high precision tests have been carried out during the solar or lunar eclipses of 1982 to 1990. None abnormal phenomenon has been found. To improve the measurement precision, several antidisturbance methods and the method of non-linear property correction of the hanging wire have been used. The measurement precition, 9.6×10^(-8) and the maximum relative fluctuation of the period change value, 9.6×10^(-8) have been reached respectively.
