| 摘 要： | 本文在随机波浪底部剪应力的研究中引入了波浪谱的概念。根据浅水波的特点，将波浪谱作为输入谱，通过传递函数确定作为输出谱的随机波浪作用下的底部剪应力谱。本研究中研制了一套底部剪应力测量仪。对于层流边界层得到了底部剪应力谱的理论解，并得到了实验的检验。

| Abstract: | The concept of wave spectrum is applied to the study on bottom shear stress under random wave action.According to the wave characteristics in shallow water,the wave spectrum is used as the input spectrum to determine the bottom shear spectrum through the transmission function and the output spectrum is obtained as the result.The instrument for measuring the bottom stress is developed. |

| Keywords: | random wave wave spectrum laminar boundary layer bottom shear stress spectrum |
