摘要：
The crystal structure of SrRuO3 at high temperatures has been studied at fine temperature intervals using high-resolution synchrotron diffraction. It has been shown that SrRuO3, orthorhombic in space group Pnma, at room temperature, changes by a continuous transition to a structure in Imma at about 685 K, then by a discontinuous transformation to tetragonal I4/mcm at about 825 K, and finally, continuously, to cubic at near 950 K.
