In this paper, the Maslov theory was introduced. By τ-p transform, seismic data is transformed from space to ,〖WTBX〗 and phase ( p s, p r ,τ) space. Then it is combined with Born inversion, and deduce the high-frequency asymptotic solution of migration operator amplitude in phase domain.

引人Maslov理论，利用τ-p变换将数据从空间分别变换到和及( p s ， p r ，τ)空间中，并将其结合到Born反演中，推导出了相空间偏移算子振幅的高频渐近解。

The implementation steps are that the seismic data is collected; the Fourier transform is made for the seismic data at a certain time window; a low pass filter operator of the time domain with an interception frequency of FE and a sampling rate of DT is calculated, which is taken as the equivalent N point smooth operator; FE and DT satisfy the equation that FE*DT is equal to X*DF*1.024; the estimate value of the amplitude spectrum of the seismic wavelet and the reverse wavelet are obtained, which are convoluted with the original seismic data; and the deconvolution seismic data of the time window is obtained.

实施步骤是采集地震数据，对某一时窗的地震数据做傅立叶变换，计算截止频率为FE和采样率为DT的时间域低通滤波算子作为等效N点平滑算子，FE与DT满足FE*DT＝X*DF*1.024，进而得到地震子波振幅谱估计值和反子波，再与原始地震数据褶积，得到该时窗的反褶积后地震数据。

It is found that the change of the frequency characteristics of chaotic system occurs mainly at the frequency band of the chaotic system, in which the input signal exists. The amplitude of the input signal doesn't influence the distortion of the output signal when masking signal is extracted by Oppenheim's chaotic masking.

研究发现，混沌系统频率特性的变化主要发生在输入信号的频率位於混沌系统频带内的情况下；输入信号幅度的大小，不影响输出信号的失真。

The results show that the change of modulation period and modulation depth affect the period of soliton interaction and the difference of relative amplitude barely affects period of soliton interaction. In particular the lattice soliton interaction is effectively avoided by opposite phase soliton.
