The characteristics of the stationary wave are presented in this paper, including its stability and wave celerity.
对驻波的有关特性，如稳定性和波速进行讨论，并分析上述诸多因素的影响。
The neutral stability curves and the character parameters are given, including the temporal and spatial growth rate, the critical wave number, the maximum wave number and the wave celerity.
获取表征液膜稳定特征的中性稳定性曲线、扰动的时间和空间增长率、临界波数、最大波数、波速的变化趋势；
For breaking wave the horizontal particle velocity can be taken as the wave celerity, since the wave is breaking when horizontal particle velocity is equal to or larger than the wave celerity.
而对于破波，质点的水平速度应该等与波速，由于破波产生的极限就是质点的水平速度等于或大于波速。
