| 摘 要： | - Based on the principle of conservation of wave action flux and the principle of linear superposition of stationary random process, the transformation of spectrum for wave surface elevation, horizontal velocity and acceleration in steady uniform current are discussed in this paper. A comparison between the calculation by spectrum analysis and by regular wave method is given also. It is shown that spectral method gives a more reasonable result, especially for the calculation of velocity and acceleration field. The theoretical results agree well with model test data.
