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。

BACKGROUND: The NarcotrendTM is a one-channel electroencephalogram monitor of the level of sedation. It is based on a visualEEG scoring system, which was developed by Loomis and modifiedby Kugler, to yield a visual expert classification schemefor differentiation of six levels of sedation, whichare subdivided into 16 substages.

In these lasers, a section of Erbium doped fiber without undergoing bump used as saturatable absorber. A self-written grating may be formed by stable standing wave in this absorber. Because selfwritten grating possesses a characteristic of very narrow rejection band and can suppress any other side-band effectively, so the multi-longitudinal mode and mode jumping in other normal fiber ring laser are removed in this one.
