摘　　要：根据廿面体准晶点群及群的矩阵表示理论,详细地导出了廿面体准晶的声子应变场和相位子应变场的不变量,进而得到与Levine等一致的廿面体准晶弹性能表达式。The explicit derivation for the invarables of the phonon and phason strain fields in the icosahedral quasicrystal is given with the matrix representation theory of the group in quasicrystal structure. Then, the expression for elastic energy of the icosahedral quasicrystal is obtained, which agrees with that in Ref. 1.
