   在主成分分析的基礎(chǔ)上，基于協(xié)方差平穩(wěn)過程理論和線性算子譜分析理論，本文提出了譜主成分分析。
3. If the covariance stationary processes are one dimension , for given data , covariance function and spectral density function can be estimated , and there is no need to select kernel function and its parameters
   如果協(xié)方差平穩(wěn)隨機(jī)過程的狀態(tài)是一維的，對給定的樣本點(diǎn)，給出了協(xié)方差函數(shù)的估計和其對應(yīng)譜(密度)函數(shù)估計，而不必選擇核函數(shù)及其參數(shù)。
4. We proof the covariance function of covariance stationary processes is equivalent with mercer kernel function . that is , the covariance function of covariance stationary processes is a mercer kernel function ; in reverse , for a given mercer kernel function , there exists a covariance stationary processes , and the covariance function corresponded to this covariance stationary processes is the given symmetry positive - definite kernel function . it means that the covariance function is equivalent to symmetry positive - definite kernel function
   首先建立了協(xié)方差平穩(wěn)過程的協(xié)方差函數(shù)與積分方程中對稱正定mercer核函數(shù)的等價關(guān)系，即協(xié)方差平穩(wěn)過程的協(xié)方差函數(shù)是對稱正定mercer核函數(shù)，反過來，對給定的對稱正定核函數(shù)，證明了存在協(xié)方差平穩(wěn)過程，使得此協(xié)方差平穩(wěn)過程對應(yīng)的協(xié)方差函數(shù)恰好為給定的對稱正定核函數(shù)，這說明協(xié)方差函數(shù)和對稱正定核函數(shù)是等價的。
