| Abstract: | Using our new developed GRAPE system[1], we calculated the group theoretical criteria in the Landau theory of the second order phase transi- tions. The possible directions of the second order structural phase transitions at r point for all 230 space groups were tabulated. Some errors in several existing tables and published results are discovered and corrected. |
