通過對模型的系統辨識,對系統的「慢時變」現象作出了合理解釋,並發現系統在1994年以後發生了「快時變」 ,從而說明人為開采量從1995年開始迅猛增加:另一方面,自相關分析表明其宏觀周期基本不變,說明人為開采量還沒有達到足以改變其宏觀頻率的程度。To analyze conveniently, analysis personnel regularity need to make the operation of background color filling, anode 、 cathode filling, gradual change filling of anode and cathode to eliminate burr phenomena and mosaic phenomena during the filling process. earthquake interpret deal with a lot of data, a mass of proportion operation, coordinate conversion and coordinate mapping must be dong in the plot process, it may frequently appears the phenomena of memory deficiency, graphics refurbish in low speed, graphics overlap and twinkle, so it make use of the technique of memory mapping document, memory dc plotting and local plotting twice and so on to implement quickly and top - quality plotting of lots of gigantic graphics and implement continuous and rolling display
分析人員為了方便分析,也經常需要把波形進行底圖彩色填充,正級、負級填充,正負極的彩色漸變填充,並消除在填充過程中出現的毛刺現象、馬賽克現象。因地震解釋所涉及的數據量很大,在繪圖過程中要進行大量的比例運算、坐標轉換及坐標映射等,就會經常出現內存不足、圖形刷新速度過慢、圖形重疊和閃爍等現象,所以需要採用內存映射文件、內存dc繪圖、局部重繪等技術,實現大數據量巨幅圖形的快速度、高質量繪制以及圖形的連續滾動顯示。But the phase changes many times of in while the range changes within a range - bin, thus ambiguity will occur in the phase measurement. to avoid the ambiguity in measuring the phase of the fft, the sampled data are divided into two segments, then apply fft on each segment of data separately
,因此可以用來估計距離(頻率x但是由於兩個fft的相位差隨距離的變化比fft的相位本身隨距離的變化慢很多,因此利用分段fft相位差估計距離要求fft相位測量誤差很小,為此本文又提出了利用分段fft的相位差消除相位測量模糊而用其中一段fft的相位估計距離的方法。Rub - impact analysis of rotor system with slow - varying mass
