无椭球进动的短Foucault摆
A Short Foucault Pendulum Free of Ellipsoidal Precession
摘要:
本文提出了一种定量地消除球摆因椭球运动而产生的内禀进动的方法。消除这种不必要的进动使福柯进动由于地球的转动容易观察。该方法是不敏感的大小和方向的扰动力导致椭球运动。我们证明,一个短(三米)的钟摆可以被推在一个控制的方式,使福柯进动占主导地位。该方法使房间高度或桌面傅科摆的建立更加准确和实用。
英文摘要:
A quantitative method is presented for stopping the intrinsic precession of a spherical pendulum due to ellipsoidal motion. Removing this unwanted precession renders the Foucault precession due to the turning of the Earth readily observable. The method is insensitive to the size and direction of the perturbative forces leading to ellipsoidal motion. We demonstrate that a short (three meter) pendulum can be pushed in a controlled way to make the Foucault precession dominant. The method makes room-height or table-top Foucault pendula more accurate and practical to build.
