摘　　要：用群论方法导出具有轴转动群SO(2)对称性的三阶非线性弹性系数张量的一般形式。指出具有十次对称轴的准晶的声子型三阶非线性弹性系数张量具有围绕十次对称轴的任意旋转对称性。The general form of the third-order nonlinear elastic coefficient tensor having the symmetry of the group SO（2） was derived with the help of group theoretical methods. It is indicated that the third- order nonlinear elastic coefficient tensor for quasicrystals with ten-fold symmetry axis has an arbitrary rotation symmetry about the ten-fold axis.
