摘要
用周期为916秒的扭秤和48.3秒的扭摆分别在乌鲁木齐和广州对1987年9月23日的日环食进行引力效应的观测,在4.1×10^(-5)和1.5×10^(-6)的精度范围内没有发现Saxl.E.所观测到的扭摆周期突变现象。
We observed gravitational effect during the annular solar eclipse occurrence on Sep.23, 1987 by means of a torsional balance, laid on Urumqi, and a torsional pendulum, laid on Guangzhou. Their periods are 916s and 48.3s, their precisions are 4.1×10^(-5) and 1.5×10^(-6) respectively. The abnormal phenomena of abrupt change of period of torsional pendulum, which had been seen by Saxl E., was not observed.
