RESULTS OF USING A TORQUE PENDULUM TO OBSERVE THE LUNAR ESCLIPE
用扭摆观测月食的结果

We discussed here the importance of the gravitational anomaly observation and suggested that the use of torque pendulum for the lunar esclipe observation would be a possible effective method to survey the gravitational anomaly.We used a torque pendulum which has a great improvement in precision to observe the lunar esclipe on 6 Sept. 1979 in Peking and had observed an obvious anomaly. The result was similar to that of Saxl's observation.We also suggested a method to improve the observation.
