  1. Due to existing signal processing technology ’ s shortage such aslow measurement, narrow measurement range precision and other poor performance, we introduced a high - precise signal processing technology : firstly, to get power spectrum with hanning windowed welch modified periodogram, search its peak value frequency ; secondly, to apply zooming analysis via goertzel algorithm ; at last, to get a highly precise doppler frequency with energy centrobaric rectifying algorithm 。 the simulating result indicated that this technology introduced could get accurate doppler frequency 。 depending on above discussed technology, we designed a signal processing scheme, and developed a signal processing system. the running result showed high performance, verified the feasibility and reliability of the highly precise signal processing technology introduced. in a word, the technology improved ldv ’ s performance such as measurement precision, measurement range, dynamic response time 。 and it will have a wide application foreground

    針對存在的缺點,本文提出了一種應用於激光多普勒測速的高精度信號處理技術,即首先利用加hanning窗的welch修圖演算法得到信號功率譜,搜索其譜峰值頻率,接著利用goertzel頻譜細化演算法對搜索的譜峰進行細化分析,再引入能量重心頻譜校演算法對細化后的譜峰進行校分析,從而將離散頻譜分析演算法、頻譜細化演算法和頻譜校演算法三者有機結合起來,充分發揮各自的優點:通過加hanning窗的welch修圖演算法快速得到功率譜及峰值頻率,通過goertzel演算法獲得分析頻帶的高解析度頻譜,然後通過能量重心校演算法對細化后的頻譜進行高精度校,這樣不僅保證了演算法的高效性,而且大大提高了分析的精度。
  2. Your own history books will tell you about many of the other cycles, the smaller cycles from the apes into homo erectus, homo sapiens and cro - magnon man, but it is so much more than that

    你自己的歷史的書將告訴你關于許多的其他,較從猿人到直立猿人,智人和克魯麥農人,但是它是比那多了許多。
  3. Studied periodic function and its least positive period

    摘要研究了函數及其最小正周期的若干問題。
  4. It shows that hard layers barely affect the ground motion and can thus be neglected in general. the soft layers, on the other hand, can influence the ground motion greatly, i. e., seismic response will decreases when the period less than 0. 1s and it increases when period greater than 0. 3s, but it will not change significantly for the long period over 3s. therefore the whole effect of the soft layers on earthquake ground motion in fact depends on the characteristic frequencies input

    研究結果表明,硬夾層的影響很,一般情況下,可以不予以考慮;軟夾層有較顯著的影響,其影響主要表現為:對於0 . 1s的高頻段反應減,對大於0 . 3s的較長段反應增大,而對長達3s及以上段反應幾乎無影響,因此,軟夾層對場地地震反應影響的總體作用是增大還是減反應,取決于計算基底輸入地震動的頻譜特性。
  5. Depicting the dynamic features of the minimum risk hedge ratios with diagonal bekk models which capture the interaction of spot and futures currency markets concludes that hedging does alleviate exchange rate risk, although different hedging strategies rank in hedging effectiveness according to their respective duration

    採用對角bekk模型來捕捉貨幣現貨與貨市場的交互影響,從而刻畫風險化套比率的動態特徵,結果表明,套保值能減少匯率風險,但具體的套保值策略的效率高低排序與避險頻率相關。
