摘要：

Pressure-temperature dependence of modulation wavenumber was measured by X-ray diffraction in the region of 295 less than or equal to T less than or equal to 400 K, 0 less than or equal to p less than or equal to 1.3 GPa. Contour map and phase diagram were drawn on p-T plane. Crystal structure of the high pressure phase with modulation wavenumber q = 0 was analyzed using X-ray diffraction data at p congruent to 1 GPa and T = 295 K.
