Frequency band

Its only dif-ference to this latter one is that high S/N contents in mid frequency band are ex-trap0lated to obtain prediction operators of high and low frequency bands, by usingintertrace .

不同之处是它利用了有效反射信号和线性（或近似线性）干扰波的道间时差及能量的差异，以及有效信号同相轴的所有频率成分具有相同时差的假设条件，运用信噪比较高的中频段频率成分外推来求取高、低频带的预测算子。

High-resolution processing methods applied to stacked seismic data are ad-vanced on the basis of signal analysis theory so that we can widen the effective seis-mic frequency band by high-frequency logging informations, compress and shape wavelets through deconvolution etc.

其中心思想是利用测井的高频信息，拓宽地震道的有效频带，利用反褶积等手段压缩、整形子波，提高地震资料的分辨率。

Based on the theory of parametric vibration, the concept of parametric resonance frequency band of the elevator rope is presented.

建立了包括钢丝绳参数激励横向振动在内的电梯系统动力学模型,基于参数振动的有关理论,提出了"电梯钢丝绳参数共振频带"的概念:在电梯系统中,导致钢丝绳横向参数共振的垂直激励频率不再局限于一个单一的数值及其邻域,而是一个较宽的数值区间,该数值区间的上下限分别是钢丝绳横向振动一阶固频上下限的2倍。
