| - | 文献阅读的一些收获：1、 When the <color #ed1c24>amplitude</color> of the excitation exceeds a critical value（临界条件？另一文献描述为加速度a达到临界）, standing wave patterns are formed on the surface which oscillate at half the frequency of the drive. | ||
| - | 2、For large enough containers（临界？）, the surface pattern becomes approximately independent of the boundaries, and line, square, hexagonal, triangular, and 8-fold quasiperiodic patterns have been observed. | ||
