By using Fourier transformation, the originalwave-front can be recovered with higher precision and in more details.
在理想情况下，利用离散傅里叶变换及其性质，能精确恢复原始波面。

The result shows that P PEM is a simple, clear and practical originalwave field model, which can be widely used in coastal works, such as the selection of harbour sites.
事实证明：P-PEM是一种简洁、实用的原始波场计算模型，适用于海岸工程方案规划比选等诸多领域。
