However, various methods are used to suppress surface waves from shooting to receiving in the process of seismic survey, thus research should be carried out in the following aspects:① joint inversion with surface wave, refraction first break and microlog data;② offset range and the relation between group interval and surface resolution suitable for use in surface wave analysis;③ the influences of lateral relief of array on propagation of surface waves;④ method for Hi-Fi purification of surface wave signals;⑤ method for extracting dispersive curve through time-frequency analysis;⑥ forward modeling and in-version methods of surface wave in view of three-layer structure.

但石油勘探从激发到接收，都采取各种方式来压制面波，因而需要开展多方面的研究：①结合面波、折射初至波和微测井信息的联合反演；②地震记录中适合面波分析的炮检距范围、道间距与表层分辨率的关系；③排列横向地形起伏变化对面波传播规律的影响；④高保真提纯面波信号的方法；⑤运用时频分析提取频散曲线的方法；⑥针对三层结构的面波正反演方法。

First, by taking into account not only interband effects but also intraband effects, such as carrier heating , spectral hole burning , two-photon absorption and ultrafast nonlinear refraction and the interaction of control pulse and signal pulse in SOA, the relationship between the performance of TOAD (including flatness of switching window, chirp of output signal and extinction ratio of the demultiplexed signal) and the parameters of input pulse (including the wavelength and power of control and signal pulse) are studied.

首先，在考虑到由于带内效应，诸如载流子热效应、谱烧孔效应、超快非线性折射效应和双光子吸收效应而导致得非线性增益压缩效应以及控制光和信号光相互作用情况下，研究了TOAD的各性能参数，包括开关窗口的平坦性、输出信号的啁啾特性、解复用信号的消光比特性等与输入控制光和信号光的波长及功率的关系，在此基础上对TOAD性能进行了优化。

Additionally, we developed a Approximating Refraction by this new methods.
