14. 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(shù)不能利用正交積分來實(shí)現(xiàn)譜分解.僅有某些特殊的非正交函數(shù)可以通過積分變換實(shí)現(xiàn)譜分解.本文提出了反射陣的概念,揭示了非正交函數(shù)譜分析的鏡像對(duì)稱性.任何能夠建立起反射陣的元函數(shù)存在著它的逆元函數(shù),并且任何基于該元函數(shù)的譜向量同時(shí)也存在著基于逆元函數(shù)的逆譜向量.元函數(shù)對(duì)與譜向量對(duì)通過反射陣建立映射關(guān)系.利用這種對(duì)稱性,非正交函數(shù)可以象正交函數(shù)一樣使用積分方法獲得譜分解結(jié)果,而不必使用求解逆陣的方法,從而為非正交函數(shù)的譜分解提供了便捷、實(shí)用的方法
