结果表明，若仅是为了测定点的垂直位移的高程速率，增加重力测量数据后对形变分析的精度增益十分有限。

Itturns out that the accuracy increase is quite limited by using gravity observation to analyse vertical deformation, if the aim is only to determine point vertical displacement and its velocity.

通过单摆装置可以方便地研究单摆的振动周期与摆长关系和测定当地的重力加速度。

Using the single pendulum, we can research the relationship between the period of oscillation of it and the length of it and measure local acceleration of gravity.
