  1. The other research purpose is to discover characteristic information and reliable methods of reflecting spinal cord damage. due to typical damage indicators, amplitude and latent period, have bugs such as limited information and weak stabilities, this project recommends applying time - frequency analysis to monitoring spinal cord function. through analysing and comparing typical signal with stft and cwt, it is proved indicators under time - frequency distribution can be better in reflecting signal changes, espcially the wavelet transformation

    針對目前ep監測中判定脊髓損傷的指標(波幅和潛伏期)存在信息量相對較小、穩定性較差的缺陷,本課題提出用時頻分析技術對術中脊髓功能監護進行研究,通過立葉變換和小波變換分析和比較典型信號的時頻分佈,證明時頻特徵參數能更有效的提取信號的變化信息。
  2. In section 4, by making use of the fourier transformation for spatial variables and starting from the nonparaxial propagating equation of ultrashort pulsed beam in temporal frequency domain, the nonparaxial solution basing on the paraxial propagating solution was derived, which come to exact solution by iterative of the paraxial integral solution

    在第四節里,通過採用空間變量的立葉變換和用時間頻率域下的非傍軸傳輸方程,我們得出了超脈沖光束傳輸的非傍軸的修正方法。
  3. The computer simulations show the validity of the models. 3. joint estimation of the time delay and doppler frequency based on short - time fourier transform ( stft ) and time - frequency analysis are studied to estimate the parameters of the underwater target echo

    針對主動回波信號參量的估計問題,重點研究了立葉變換、時頻分析進行時延和多普勒頻移聯合估計,進而進行目標距離和速度參數的估計。
  4. “ no , no , no , ” replied this individual , who was blond and vigorous and by nature a little irritable and contentious

    重神似不重形似「這是在討論翻譯問題時常說的一句話。雷?人間喜劇,約翰。克斯朵夫,最難應付的是原文中最簡單最明白而最
  5. The method and theory of time - frequency analysis based on short - time fourier transformation are studied and the wave arrival points of easy component are determined by making software and using time - frequency analysis

    研究了基於里葉變換的時頻分析方法理論,並通過編制軟體用時頻分析方法確定各組分波的波至點。
  6. Firstly, in the paper a family of integral solution representing ultrashort pulsed beam propagating in free space have been studied by using the co - moving frame coordinates and the fourier transformation for time variable in terms of well - known paraxial approximation. and the pulsed gaussian - like beam solution can be obtained as a especial solution of the integral solution, where including the pulsed gaussian beam

    首先立葉變換和惠更斯-菲涅爾衍射積分公式,我們給出了傍軸標量場近似下超脈沖光束傳輸的基本積分解,並進一步得到了用卷積形式表示的脈沖類gauss光束解( pulsedgaussian - likebeam )的普遍形式解。
  7. Wavelet transform is a wonderful method, which have adjustable resolution in time and frequency fields leading to more subtly analysis for a signal segment. it works in a good pattern according with the rule of human ears distinguishing frequencies from voice. for stft having inevitable disadvantages in analysis of unstable signal such as speech signal, as a result of study on wavelet theory and speaker recognition techniques, two feature parameters, iwptc ( incomplete wavelet packet transform coefficients ) and wptc ( wavelet packet transform coefficients ), are got based on wavelet transform

    針對立葉分析在提取說話人特徵參數時的缺陷,本文通過對小波理論和說話人識別技術的研究,借鑒了一種傳統的基於聽覺機理的特徵參數mfcc ( mel頻域倒譜系數) ,用小波變換、小波多分辨分析和小波包變換,構造出了兩種基於小波變換的說話人識別特徵參數: iwptc (不完全小波包變換系數)和wptc (小波包變換系數) 。
