摘　　要：８０年代发展起来的小波分析，作为一种崭新的数学分析方法，适宜于分析信号的局部特征，在诸多研究领域得到了广泛的应用［１～４］．本文拟通过对现场实测的碎波带波面记录，通过小波变换分析碎波带能量波动的多尺度性，并进行统计上的检验．１资料采集现场工作位于粤东...Based on the wave data of two stations measured in a beach and surf zone under different wave conditions,the wavelet spectra were computed by using wavelet transform and the statistically significant levels were tested.The results showed:① The remarkable multiple scales of wave energy oscillations exist in the surf zone;② Under normal wave condition,wave energy is mainly distributed in the wind wave frequencies,and transferred from high to low frequencies while the incident wave propagates from the outer station to the inner station;③ The wave energy increases towards infragravity wave frequencies under the high waves,and the phase relations between two stations are in accordance on the significant scales of infragravity waves.
