The clues and techniques to improve the resolution of data processing are 1 ) removing the affection of near surface factors on data acquisition, including static correction and noise eliminating technique etc, 2 ) broadening the frequency band of pre - stack seismic data, including amplitude compensation and pre - stack deconvolution etc, 3 ) improving s / n ratio of high frequency and weak reflection signals through multiple coverage with high precision velocity analysis, residual static correction and high - order nmo, raising " dead line of high frequency reflection ", and 4 ) identifying post stack effective reflection frequency band, enhancing dominant frequency and so on
主要包括：消除近地表因素對資料採集的影響，包括靜校正和噪音壓制技術等；疊前拓寬地震資料領帶，包括振幅補償和疊前反褶積技術等；藉助高精度速度分析、剩餘靜校正和高次項nmo技術，通過多次覆蓋疊加，消除資料中隨機噪聲干擾、提高資料信噪比，尤其是高頻端反射信息的信噪比，改善高頻反射和弱反射信號信噪比，提高「高頻反射死亡線」 ；疊後有限反射頗帶識別、抬高優勢頻率等。 -
Collision line broadening
碰撞譜線致寬 -
With time - evolution - operator, it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of gaussian line - shape in a homogeneous broadening two - level system. the oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level
引入時間演化算符，證明均勻增寬二能級體系在飛秒激光脈沖對作用下上能級激發態布居是周期性變化的，它以飛秒脈沖對之間的延時為時間軸，以該原子能級之間的躍遷頻率為振蕩頻率 -
First, its opening make learner rearrange instruction content and instruction strategy, embodies better adaptability, accomplishes willing learning going away the confine of the time and space. second, it can build a cooperation learning environment, which learners are capable of enlightening, helping each other, broadening thought and idea, advance oneself. third, it realizes that all resource is shared global, on - line learner can acquire the latest information of some subject
