吕建忠，唐小青，彭世春,等.听性脑干反应相位谱分析客观诊断中高频听力损失j .耳鼻咽喉-头颈外科， 1997 ， 4 : 131 - In the paper , some key technique such as low - order modes correction for wave - front error , normalized phase power spectrum , atmospheric turbulent phase structure function , the residual phase structure function after low - order correction and strehl ratio are all analyzed
提出了利用自适应光学系统校正低阶模式波前误差的方法与理论依据，引入规格化的相位谱，推导了大气湍流相位结构函数、低阶模式校正后的残余相位结构函数以及斯特列尔比。 - In order to obtain a high - quality speech codec , the phase information of speech should be included in codec . in this thesis , a method for quantizing the phase of sew ( slowly evolving waveform ) and reconstructing sew ’ s phase with cubic polynomial interpolation is given based on the perceptual weighting analysis - by - synthesis ( a - b - s ) vector quantizer for the phase spectrum in wi coder
本文基于感觉加权相位谱分析合成( abs - analysis - by - synthesis )矢量量化方法,给出了一种wi编码器中慢渐变波形( sew - slowlyevolvingwaveform )的相位信息量化及合成端相位的三次多项式插值重建方法。 - Results showed that the samples of different heat treatment technologies of 38crmoal can be comparatively preferable distinguished by real spectrum and phase spectrum of fft . further research on real and image spectrum of fft discovered that using energy spectrum of real and image of fft to discriminate these samples is more compact and convenient
研究发现用ut信号fft的实部谱图结合相位谱图能够相对较好的区分38crmoal钢的不同热处理状态：对ut信号fft的实部和虚部谱图的进一步研究表明，用ut信号fft的实部和虚部能量谱来区分热处理状态更为简捷和方便。 - Fourthly , respectively using cross correlation method for estimation of time delay , phase spectrum method for estimation of time delay and high order spectrum method for estimation of time delay , this paper measures time delay estimation of the data obtained because time delay between two signals has big importance on the testing result . through comparing three results , accurate time delay is obtained under their own different circumstances
再次，由于两信号的时间延迟对测量结果有很大的影响，因而研究了用互相关时间延迟估计、相位谱时间延迟估计和高阶谱时间延迟估计的方法对测量数据进行了时间延迟估计，结果表明，三种时间延迟估计方法在各自适应的环境下使用，都能得到比较准确的时间延迟估计值。
