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,並且任何基於該元函數的譜向量同時也存在著基於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The symmetric values about the imaginary axis of zero - poles which the unstable process lies in the open and closed right - half plane are defined as their mirror - injection
