The directionalspectrum is one of the basic characteristics of sea waves.
方向谱是海浪的基本性质之一。

The comparison shows that EMEP given a better estimation of directionalspectrum than EMLM.
而EMEP方法能够消除误差的影响，可以给出与真实的方向谱更为接近的估计值。
3
The results indicate that the relative distribution of the field wind wave directionalspectrum energy is closely related to the corresponding types of wave state.
