The three-parameter Weibull pdf and Gaussian pdf describe the distributions of every elastic coefficient accurately.

三参数威布尔分布和正态分布较好地描述了各个弹性参数的分布。

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.

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。
