The gravity is measured by nulling the beam . 重力值是通过使横臂恢复零位而测定的。
2.
The heavy damping makes it impractical to read gravity directly from the displacement of the beam . 高阻尼不能使其直接从横臂的位移读出重力值。
3.
Gravity instruments are designed to measure variation in the force of gravity from one place to another rather than the absolute force itself . 重力仪的设计是为了测量一处到另一处的重力变化，而不是绝对重力值本身。
