| 摘 要： | The new distributions of the statistics of wave groups based on the maximum entropy principle are presented.The maximum entropy distributions appear to be superior to conventional distributions when applied to a limited amount of information.Its applications to the wave group properties show the effectiveness of the maximum entropy distribution.FFT filtering method is employed to obtain the wave envelope fast and efficiently.Comparisons of both the maximum entropy distribution and the distribution of Longuet-Higgins(1984) with the laboratory wind-wave data show that the former gives a better fit
