The module of Zone Abnormal noise Processing ofOMEGA sps is an effective mothod of suppressing noise in Shot gather and CMPgather.②The noise of alternating current is suppressed by notching filter in theseismic data which dominating frequency is far from 50Hz.Otherwise,it issuppressed by mono-frequency noise suppression in the time domain of CGGsps;③The module of F-X Coherent Noise Suppression of OMEGA sps isa good mothod to suppress coherent noise.

此方法在炮域和 CMP 道集上应用效果最好；②对于工业干扰，原始资料主频远离 50Hz 时，采用陷波的方法较为简便，否则采用CGG 系统中的时间域单频压制方法；③对于相干噪音压制，OMEGA 中的频率-空间域相干噪音压制方法在知道斜干扰视速度的情况下，应用效果明显。

Through the decompositions to common-shot gathers and common-offset gathers, one can obtain common p, plane wave gathers and common P plane wave gathers which are suitable to the single square root extrapolation equation and the double square root extrapolation equation, respectively.

通过对共炮点道集和共偏移距道集地震数据的平面波分解，分别得到适用於单平方根波场外推方程和双平方根波场外推方程的共P平面波道集和共P平面波道集。

为此，从初至波的特点出发，提出了单道数据边界检测和样条插值相结合进行初至波自动拾取的方法。

Based on the conclusion, we adopt a new method to eliminate multiples, which is to use the statistic character of error, obtain inverse wavelet's estimation, correct misshaped inverse wavelets for non-orthogonality in inverse wavelet domain by the estimation. The method mainly has four steps.

在此基础上，本文提出了在逆子波域（单道自适应相减滤波的滤波算子的集合），利用其误差的概率分布特征，对逆子波进行估计，用逆子波的估计对逆子波进行校正来消除多次波的方法。

Firstly, after getting predicted multiples, we use adaptive subtraction algorithm to eliminate multiples and get some inverse wavelets corresponding to every trace in one shot gather, then construct inverse wavelets domain by those inverse wavelets. Secondly, use median filtering method to get inverse wavelet estimation in inverse domain. Thirdly, correct the misshaped inverse wavelets in inverse domain by the inverse wavelet estimation.

其步骤为：首先用SRMA方法预测出表面多次波，并对每一单炮进行单道自适应相减，得到逆子波，形成逆子波域；其次，在逆子波域采用中值滤波，提取接近真实逆子波的逆子波估计；第三，在逆子波域用逆子波估计对畸变的逆子波进行校正；最后采用校正后的逆子波来衰减多次波。

Finally, the numerical investigation of shock wave compression passage and the analysis of flow characteristics are performed and it is concluded that the pressure ratio of single stage may be equal to nine.

最后，通过对激波压缩通道进行了流场数值模拟，对其流道内的气动特性进行了分析，得出其单级压比可以达到9，充分显示出其优越的高压比特性。

Compared with ordinary detection methods, this method hasmany merits such as high resolution ratio,avoiding lots of disturbed waves,continuous collection for single trace, high energy of reflection waves and minimum offset distance.

该方法与其它常归物探方法相比，可避开许多干扰波，可单道连续采集，并且有分辨率高，偏移距小，反射能量高等特点。
