指數變換
  • exponential : adj 指數的，冪的。 exponential curve 指數曲線。 exponential function 指數函數。 exponential sum ...
  • transformation : n 轉變，變化；變形；【生物學】（尤指昆蟲的）轉化，變態，改造，改革；變質；【數學】變換；【電學】...
  1. Furthermore, the dual - exponential curve transformation needs no reference time intervals for calibration, and hence it immunes to the uncertainties such as jitter of the reference inputs

    更重要的是，雙指數曲線轉換的方法不需要參考的時間單位來作為校正輸入，因此可以避免參考時間的不確定性如時基抖動所造成的誤差。
  2. The second one is a brand - new method based on dual - exponential curve transformation

    第二種則是依據一個稱為雙指數曲線轉換的全新方法。
  3. The type of the base function of wavelet analysis is not single, while the ft has only the sine ( or cosine ) function or exponential function. wavelet transformation has the character of multi - resolution analysis. wavelet transformation can analyze the signal in any precision ( resolution ) at any part of time and frequency according to the different translation factors and dilatation factors

    小波變換具有多解析度分析的性質，對應于不同的伸縮因子和位移因子，小波變換能對信號的任何時間（空間）段、任何頻率段進行任何精度（解析度）的分析，在非平穩信號（包括瞬間信號）的分析中具有很大的優越性，分析時，在信號的低頻部分具有較高的頻率解析度和較低的時間解析度，在高頻部分則具有較高的時間解析度和較低的頻率解析度，被譽為「數學顯微鏡」 。
  4. The optimized parameters of high - frequency in bacillus thuringiensis plasmid - free mutant bmb171 by electroporation was studied. it showed that a highest electro - transformation frequency could be obtained, when sg solution was used as the buffer, and a 10. 0 kv / cm of field strength, one time of pulse as well as a growth phase of recipient cells at the exponential phase ( od650nm value was 0. 2 - 0. 3 ) were selected

    對用電脈沖法轉化蘇雲金芽胞桿菌受體菌bmb171優化條件的研究結果表明，採用sg溶液作電脈沖緩沖液，用10 . 0kv cm的脈沖場強和1次電脈沖（ 4 . 6ms ） ，以及採用對數前期（ od _ （ 650 ）約0 . 2 0 . 3 ）收獲的受體菌，可以達到最高轉化頻率。
  5. The contributions of this dissertation is listed below. aiming at existing defects of traditional beeline detection by hough transformation ( ht ) arithmetic, such as large storage space consuming, imprecise beeline detection effect and information loss of image feature pixels etc, we suggest two new beeline detection methods. ( 1 ) based on infinite symmetry exponential filter and its recursion arithmetic, new beeline detection methods can get exact direction of image edge pixels in advance, so it reduces highly the calculation quantity of the conventional ht, and improves the speed and the precision of beeline detection greatly

    本論文的主要研究成果列舉如下：針對傳統直線檢測霍夫變換（ houghtransform ， ht ）所存在的參數空間存儲量大，直線檢測不精確以及圖像特徵點信息丟失等缺點，提出兩種新的直線段檢測演算法： （ 1 ）提出一種基於無限對稱指數濾波的ht直線段檢測演算法，在進行邊緣檢測的同時，提前精確定位邊緣點的方向，減少了ht的運算量，提高了運算速度和檢測精度，而且整體演算法便於硬體的并行執行，使得實時處理成為可能。
  6. An exponential transformation method for constructing high - order schemes of convection - diffusion equations on non - uniform difference grids

    構造了一個二階的基本無振蕩
