球形地球对单摆的影响
Effect of the spherical Earth on a simple pendulum
摘要：
本文研究球形地球引力场中单摆的周期。实际上，与通常使用的平坦地球近似相比，重力被增强，使得钟摆的周期缩短。我们讨论了平地球近似，并显示时，由于球形地球的修正可能是感兴趣的。
英文摘要：
We consider the period of a simple pendulum in the gravitational field of the spherical Earth. Effectively, gravity is enhanced compared with the often used flat Earth approximation, such that the period of the pendulum is shortened. We discuss the flat Earth approximation, and show when the corrections due to the spherical Earth may be of interest.
