在郯庐带中南段重力网进行的重力变化的测量和研究表明:可以引用高精度绝对重力测量控制相对网误差;在绝对重力测量尚不广泛使用时,航运重力测量是可行的辅助重力测量方法;1981年和1982年的重力变化较小。
Measurement and study of gravity changes in the middle and southern sections of Tanlu with the results show that the relative net error can be controlled by high precision absolute gravimetric measurement. When absolute gravimetric measurement is not yet widely used, gravity measurement of shipping is feasible. The gravity change in 1981 and 1982 was small.
