1. The spectral analysis of non - orthogonal functions cannot be obtained by orthogonal integration method . only the spectral analysis of some particular non - orthogonal functions can be realized by integral transformation . thus , the concept of reflection matrix is proposed and the mirror symmetry of spectral analysis for non - orthogonal function is revealed . any element functions whose reflection matrix can be obtained possesses its inverse element function . the spectral vector corresponding to an element function possesses its inverse spectral vector corresponding to the inverse element function . by reflection matrix the mapping relation of element function pair and spectral vector pair can be established . spectral analysis of non - orthogonal functions can be obtained with this symmetry by using the integration method as in the case of orthogonal functions , instead of calculating the inverse matrix as usual . so a convenient and practical method for spectral analysis of non - orthogonal functions is offered
   非正交函數不能利用正交積分來實現譜分解.僅有某些特殊的非正交函數可以通過積分變換實現譜分解.本文提出了反射陣的概念,揭示了非正交函數譜分析的鏡像對稱性.任何能夠建立起反射陣的元函數存在著它的逆元函數,并且任何基于該元函數的譜向量同時也存在著基于逆元函數的逆譜向量.元函數對與譜向量對通過反射陣建立映射關系.利用這種對稱性,非正交函數可以象正交函數一樣使用積分方法獲得譜分解結果,而不必使用求解逆陣的方法,從而為非正交函數的譜分解提供了便捷、實用的方法
