The Foucault's pendulum is a well-known scientific tool.The transmission process in China has been sorted out through a literature query,and a relevant study has been undertaken on this basis,which is divided into four parts:(1)a brief review of the experimental exploration of the Earth's rotation prior to the invention of the Foucault pendulum and the invention process of the Foucault pendulum;(2)an overview of the diffusion process of the Foucault pendulum in China;(3)an investigation into the use of the Foucault pendulum in textbooks;and(4)an analysis of an experimental scenario in which our physicists used the Foucault pendulum to assess the gravitational acceleration.
