基本解釋
- 莫萊
英漢例句
- In the paper, using Morlet wavelet transform and EOF analysis to analyze Polar Vortex and SAH at 100hPa Geopotential Height.
利用NCEP/NCAR高度場(chǎng)資料進(jìn)行EOF分解;并對(duì)冬、夏極渦與夏季南亞高壓的面積進(jìn)行Morlet小波變換. - Morlet, J., Arens, G., Fourgeau, E. and Giard, D., “Wave propagation and sampling theory”, Geophysics, Vol. 47, No. 2, pp. 203-236, 1982.
郭瑋明、高家俊、莊士賢，“應(yīng)用小波理論分析短時(shí)波速與波向之研究”，國(guó)立成功大學(xué)水利及海洋工程研究所碩士論文，1997。 - This method is using Morlet wavelet transform,phase compensating, filtering ,extracting the modulation spectrum of radar target by FFT, then radar target is detected.
此方法是利用小波變換 ,得到雷達(dá)目標(biāo)回波信號(hào)的頻率調(diào)頻指數(shù) ,對(duì)信號(hào)進(jìn)行相位補(bǔ)償 ,然后濾掉信號(hào)中的機(jī)身頻譜和多普勒頻譜 ,再進(jìn)行相位補(bǔ)償 ,用 FFT(快速傅立葉變換 )就可以得到目標(biāo)的調(diào)制譜 ,由此實(shí)現(xiàn)目標(biāo)識(shí)別。 - Data of WFD calculated recent 50a is analyzed by means of EOF and Morlet technique in order to find distribution of space-time and Variation of multiple time scale on WFD.
對(duì)計(jì)算出的近50年晚霜凍害資料進(jìn)行EOF分析和Morlet分析,以發(fā)現(xiàn)晚霜凍害的時(shí)空分布與多時(shí)間尺度變化規(guī)律。 - Research shows that the feature parameters by the Morlet wavelet transform 3-D distribution figures can be used to distinguish point to point PD,point to plate PD and surface PD.
理論和仿真實(shí)驗(yàn)分析表明,小波變換三維分布圖提取的特征參數(shù)可以作為識(shí)別局部放電的新特征量,這些特征量作為人工神經(jīng)網(wǎng)絡(luò)的輸入量可單獨(dú)使用也可結(jié)合其它方法使用。
