A general method to quantitatively study the transient fluctuation related to the high frequency vibration in crystal growth is developed. An example during the Czochralski crystal growth has been simulated, and the simulation coincides with the experimental date. On basis of the model, the influence of vibration frequency on the transient fluctuations for temperature and velocity are elucidated. Then an available approach to control the vibration effect is proposed.
