  1. However, due to measurement, instrumental, computational, and even human errors, the measured process data always mix with noise ineluctably

    然而，由於測量誤差、儀表精度、計算誤差甚至是人為因素，過程測量數據通常不可避免地存在噪聲。
  2. This paper raised a new way for overlapping speech segregation based on sound localization cues. in this paper, we first divide the speech stream into some time - frequency regions and calculate the itd and iid of each region. then the notion of a " time - frequency " binary mask is given, which selects the target if it is stronger than the interference in a local time - frequency region

    然後求取每個小片段上的itd （到達雙耳時間上的差異性）和iid （到達雙耳強度上的差異性）值，經過實驗證明某個片段上的itd值和iid值與該片段上的信噪能量比是單調遞增關系，因此通過和域值的比較，得出掩蔽系數，來判斷每個小片段具體是屬于哪個聲源。
  3. Then by the method of computer simulation, the following jamming patterns are made quantitative analysis, radio - frequency noise jamming, continuous single tune jamming, continuous noise amplitude - modulated jamming, relayed frequency shift jamming, and the key factor which affect the quality of these jamming patterns

    然後在此基礎上，通過計算機模擬分析，定量地討論了射頻噪聲干擾、連續正弦波干擾、轉發移頻脈沖干擾以及影響它們干擾品質的因素，並以壓制系數為衡量標準，進行了干擾效能分析。
  4. Under the condition of " comparatively weak correlation between the two noises involved, coherence function is used as a frequency domain amplification factor for improving snr of the output signal to the filter and the speech enhancement effect. meanwhile, a real - time recursive algorithm is put forward in substitute for current algorithms based on short time fourier transform. the new algorithm will simplify computations and will be suited for real - time implementation together with the adaptive systems

    接著針對上述nanc系統兩路輸入信號噪聲相關性弱的情況，用相干函數作頻域增益因子來提高輸出信噪比與改善語音增強效果，同時，通過一種實時迭代演算法解決了短時傅氏變換計算量大的問題，簡化了計算，便於實時處理與實際應用。
  5. Excess noise factor

    過量噪聲因數
  6. Triangle mesh models have been established as the most general and flexible schemes to represent complex surface models in the area of reverse engineering ( re ), rapid prototyping manufacturing ( rpm ), numerical control ( nc ) programming, 3d animation, etc. but the models reconstructed from real - world data may contain unavoidable noise and many narrow triangles, so the models must be optimized and modulated under given tolerances

    三角網格模型是逆向工程、快速原型製造、數控加工編程、三維動畫等技術中常用的模型表示方法，模型的質量直接影響到產品的質量，尤其在逆向工程中，直接通過測量數據得到高質量的網格模型幾乎是不可能的。因為，測量數據中不可避免地存在各種噪聲和擾動，因此在滿足幾何精度要求的前提下，對網格模型進行優化調整，以提高模型質量就十分必要。
  7. It is a pop method to embed watermark in frequency field, in most literature, they embed watermark into the coefficients of fft, dct, or high - frequency of dwt using quantization method, we think that : embedding watermark into the low - frequency of audio signal dwt field can improve the robustness of watermark. the watermark is embedded in the maximum of subsection of approximate component the watermark signal using quantization method, for the same quantization size, the “ noise ” added to the signal is

    在頻率域嵌入水印信息，是目前一種主流的嵌入演算法，在很多文獻中，都是通過量化音頻信號的ftf系數， dct系數，或者是dwt域的高頻系數。我們認為:在小波域內的近似分量（低頻系數）中嵌入水印能夠提高數字水印的魯棒性，通過量化嵌入水印的方法，將水印嵌入到近似分量中每個分段中最大值上，因為這樣對于同一個量化步長，量化對象的幅值越大，所疊加的「噪聲」就越小，從而提高了數字水印的不可感知性。
