摘要：

The effects of uniaxial stress sigma-yy on the incommensurate (INC) phase transition of quartz have been investigated by light scattering spectroscopy. The 1q INC phase is induced between beta and the 3q INC phase and its region becomes wider with the increase of stress. Anomalies of the central peak in the Rayleigh-Brillouin spectra are observed at three temperatures, corresponding to T(il) (beta to 1q INC phase), T(i3) (1q to 3q INC phase) and T(c) (3q to alpha phase). Only at T(il), is the central peak found to have a dynamical component.
