描述了深水波群演化的实验测量。当初始陡度0.09≤a0k0≤0.28时，波群在几十个波长内快速变化。该转变产生由比初始状态更小陡度和更低载波频率的波组成的包络孤子。包络孤子的载波频率可下移多达 25%。转变过程是不可逆的，但不会导致完全随机性。
Experimental measurements of evolution of a deep‐water wave group are described. Wave groups are found to change rapidly over a few tens of wavelengths when the initial steepness 0.09≤a0k0≤0.28. The transition creates envelope solitons composed of waves with smaller steepness and lower carrier frequency than the initial state. The carrier frequencies of the envelope solitons can be downshifted as much as 25%. The transition process is irreversible, but does not lead to total randomness.
