Wavelet discussed in this paper is a basis of l2 or other spaces created by a function ( mother wavelet ) expand and contract and shift
本文討論的小波是指由一個函數(母小波)經過伸縮與平移所產生的l ~ 2或其它空間的基底。The research methods are : using the conditional probability theory to work out the moment generating function of process s ( t ) and its distribution function ; using the increasing and declining character and the convexity to compare the lundberg exponent and the ruin probability of different processes
研究方法為:利用條件概率證明過程s ( t )的矩母函數以及其分佈函數;利用增減性以及凹凸性比較lundberg指數,從而比較其相關性對破產概率的影響。This work comprises of the following parts : firstly, some research on diagnosis theory and fault signal is carried out and concluded that the diagnosis process needs wavelet analysis ; secondly, theory basis of wavelet analysis is researched. emphasis to its explanation of engineering is given. according to analyze concrete performance, the appropriate wavelet function for diagnosis is obtained ; thirdly, research on the application of wavelet transform in nonsteady signal is conducted
主要內容如下:首先,研究了小波分析在故障診斷中的意義,從診斷理論和故障信號特點兩方面說明對故障信號進行小波分析是診斷過程的內在要求;其次,研究了小波分析的理論基礎,重點說明其工程解釋,並通過分析具體的性能指標得到適合故障信號分析的小波母函數;第三、研究了小波分析在非平穩信號分析方面的實際應用,說明了小波分析對此類信號分析有著傅立葉分析不可比擬的優勢。
