摘　　要：基于Laskar J提出的频率映射分析方法,证明一种较Laskar J情形下精度更高的窗口,Blackman窗口;此窗口在Hunter C的DFT意义下比Hanning窗口精度高,有一定的理论和应用价值.Based on the frequency mapping analysis introduced by Laskar J,a window function, the Blackman-window,is proved with a higher precision compared to Laskar J＇s original case. The precision of Blackman-window is higher than that of the Hanning-window in the case of DFT used by Hunter C. This has some theoretical and applicable uses.

关 键 词：KAM理论 频率映射 窗口(权)函数
