我的手指在琴鍵上跳躍著，我激動的眼淚盡情地流淌著，無數個攝像機對著我，無數個閃光燈在閃著。簽名開始了，大家排起了長長的隊，一直排到了門外。 -
Select the rolling speed at the pull down menu, then hold down the left click on the [ rolling up ] or [ rolling down ] to control the destination blind
于下拉選單選好攪動速度后，用滑鼠左鍵按下[上移]或[下移]控制地點牌。 -
The main contents of this thesis include : ( 1 ) summarize and analysis of the theories on vibration transmission through rolling element bearings ( 2 ) based on the threshold setting and signal ’ s statistical approach, a method for solving the problems of denoise was developed ( 3 ) using sparsity and clustering, the method and hypotheses for underdetermined blind source separation was studied ( 4 ) the method based on potential function clustering was given for underdetermined blind source separation of noisy signals based on the assumption that the input distribution is sparse and the mixture procedure is linear, the attenuation matrix and the delay matrix were estimated by clustering. the approach was experimentally illustrated for the case of m = 2. the separation of the signals from bearing test bed proved that the given methods are available and reliable
在需求分析和研究現狀分析的基礎上，本論文針對如下內容進行了重點研究: （ 1 ）以滾動軸承為例，對旋轉機械振動信號的傳輸進行了歸納分析; （ 2 ）通過設定某一門限並研究信號間的統計特性，研究了旋轉機械振動信號的盲源分離過程中噪聲消減策略; （ 3 ）應用稀疏信號分析和聚類分析方法，對盲源分離中欠確定問題的假設條件進行探討並對分離方法進行了分析; （ 4 ）採用基於勢函數聚類分析的方法，研究了欠確定前提下含噪聲測量過程中信號盲源分離方法。
