摘　　要：讨论参数化谱分析方法的基本原理以及基于高阶Ｙｕｌｅ－Ｗａｌｋｅｒ方程组的参数计算方法，提出了一种新的从数据中估计谱线根数的方法，实验表明，该方法是有效的。The theory of paramctric spcctral analysis and its use in NMR data processingfield was presented．Then，an efficient method for parameter computing，ealledHigh-order Yule-Walker Equations （HOYWE） method was introdueed． This is ahigh precision method for computing the coefficients of the AR part of an ARM Amodel，therefore the rcsulting spectrum is very similar to the corresponding true spec-trum，In order to facilitate the using of this new method， a simple but effective strate-gy for choosing the true number of complex exponential components in signal was pro-posed． The computer simulation tests have justified the applicability of this strategyand the HOYWE method.
