時間模( timescales )最早是由德國w rzburg大學的hilgerstefan在1988年提出的,當時他在導師berndaulbach的指導下完成博士論文( [ 1 ] ) ,其主要思想就是把連續分析與離散分析統一起來,他發現人們對微分方程研究后往往又對相應的差分方程進行研究,而一般情況下兩者又可得到相平行的結論,於是定義了時間模上的動力學方程,即方程的未知函數的定義域是一個時間模。The statistical method of repeated data of variance analysis was used to compare the difference of oxygen partial pressure and calcium ion concentration between the acupoints and non - acupoints

由於多小波變換系數的計算是直接與其預濾波方式相聯系的,而在單小波變換系數計算中之所以能由近似表示就是因為尺度函數具有低通特性和平移正交性,由此我們研究了能滿足以上要求的預濾波,並對離散小波變換系數和連續小波變換系數之間的差異作了分析,從誤差分析結果我們可以預見:為了減少誤差我們可以通過對預濾波的進一步設計來控制。分享友人
