摘　　要：将测量的能谱认为是对信号的经典估计,提出采用AR模型对核能谱进行重新估计的方法,经过该方法处理过的能谱更为光滑,能峰变窄,各峰和总的粒子数不变。For looking measured energy spectrum as classic spectrum estimation of the input signal, the method of re-estimatlng the nuclear energy spectrum by AR model is introduced. The spectrum is smoother, energy peak is narrower and number of particle in every peak and the spectrum are fixedness, after processed by the method.

关 键 词：AR模型 核能谱 反傅立叶变换
