查找頻度 的英文怎麼說
中文拼音 [zhāzhǎobīndù]
查找頻度
英文
frequency of search-
Based on the dds technology, the waveform generator first stored data in high speed ram, then used dac to synthesize waveform by the data. many waveforms could then be generated easily. besides, the wave generator could get high performance on frequence resolution and stability, phase continuum, relative bandwidth etc. the dds technology was widely used in frequence synthesis field
基於dds技術的波形發生器以高速存儲器作為波形數據查找表、通過高速d / a轉換器對存儲器的波形進行合成，可以靈活產生多種波形，同時具有頻率解析度高、頻率穩定性好、頻率轉換快、相位連續性好以及相對帶寬較寬等特點。The fist step is to judge the damaged sub - area of the structure, which is divided into several sub - areas, using probability neural networks with neural frequencies shift ratio input, and the next step is to diagnose the exact damage location and extent using rbf neural network with the second element end strain mode of the damaged sub - area input
即按照先查找結構損傷區域，后進行損傷位置與程度診斷的思想，首先將結構分為若干個子區域，根據結構損傷前後的自振頻率變化比，應用概率神經網路，進行結構損傷子區域的判定。然後，根據損傷子區域內的應變模態變化，應用徑向基神經網路診斷結構的損傷位置與程度。By introducing an oblivious policy and sorting chinese characters in accordance with their dynamic frequencies, the algorithm made important improvements on the average search length of chinese characters, which could better guarantee the strict demand on time of any application driven by the dyanmic statistics of chinese texts
由於引進了動態遺忘機制以及根據頻率動態調整漢字順序，演算法的平均查找長度成倍縮短，從而能夠更有效地保證涉及大量漢字信息檢索操作的應用對時間性能的要求。
