The influence of the principal parameters of optical chirp reversal devices on ability to restore signal wave form and pulse duration has been analysed and simulated.
The extremal spectrum density directions of components of wind wave spectrum types are different. This indicates that wave components of different frequencies have different principal directions.
不同波场类型的风浪方向谱各组成波的谱密度极值方向不同，表明不同频率的组成波有不同的主方向。
