中文拼音 [fànshǔshèngyú]
范數剩餘
英文
norm residue-
Doing the further research on the division frequency stack on the foundation of study of predecessor, at first the residual moveout correction is done to the seismic record, make the phase axle regularity, doing foundation for the same phase stack ; then carried on division scale processing by wavelet transform ; spectrum whitening is done to each scale, the high and low frequency band need to do prolongs, the middle frequency bands only increase the value of the frequency spectrum ; several kinds of methods that estimate the value of signal - noise ratio has been studied further, and summarize their advantage and disadvantage as well as the scope of application ; the seismic record after spectrum whitening is stacked by weighting with the value of the signal - noise ratio ; then estimate the value of signal - noise ratio which is each scale section after stacking, the scale that the signal - noise ratio is big is assigned big weighting, otherwise, the scale that signal - noise ratio value is small is assigned small weight ing, and carried on weighted reconstruct to each scale section
本文在前人研究的基礎上，在分頻疊加方面做了進一步的研究。首先對地震記錄進行剩餘時差校正，校齊同相軸，為同相疊加做好基礎工作；然後對地震記錄用小波變換的方法進行分尺度處理；對各個尺度分別做譜白化，對于高、低頻段需要做頻帶延拓，中間頻段僅提升頻譜值；對于幾種信噪比定量估計的方法進行了深入的研究，並且總結了它們的優缺點以及適用范圍；對譜白化后的地震記錄用信噪比估計值作為加權系數進行加權疊加；對于各尺度的疊加剖面也進行信噪比估計，對于信噪比大的尺度給予大的加權系數，反之，信噪比值小的尺度給予小的加權系數，對各尺度疊加剖面進行加權重構。On basis of the calculation method of residue sliding force, the transfer coefficient method is improved to obtain the slide block balance method, the application scope of which is wider
在滑坡剩餘下滑力的計算方法上，改良傳遞系數法，提出了精度更高，適用范圍更廣泛的廣義不平衡推力法。As a main part of urbanization, the number of peasants in city is larger and larger with the accumlationof the surplus labour in rural area and accumlation of economic grouth in city. the most important is resocianization of the peasants in city, and criterion of behavior is highligter during the process of the resocianization. this paper repor the study conducted in meilong town, minghang distract in shanghai., by the method of investigation of question paper and issue
隨著農村剩餘勞動力的增加與城市經濟的發展，進城農民的數量將越來越大。再社會化是進城農民面臨的一個重要問題，城市行為規范的再社會化是進城農民再社會化的重要內容之一。本文主要採用問卷調查與個案訪談相結合的方法，對上海市閔行區梅隴鎮的進城農民進行了實證研究。
