Through experiments, it's found that some of light diffraction cannot be explained well using existing wavetheories of light.
通过实验发现有一些光的衍射现象，如果使用现时光的波动性理论无法很好的解释清楚。

Surface elevations and horizontal velocities Calculated or observed indicate that the non-linear wavetheories provide better results than the linear wave theory.
数值计算的结果表明，对于波面高程和水平流速值，由非线性波理论所得的结果较线性波理论的结果为好。

At present, the calculations of wave forces on Marine structures are confined to the linear and low-order non-linear wavetheories, sometimes these are not satisfied with the requirements.
