因为你曾有过回忆，所以你会心存恐惧；因为你曾有过回忆，所以你会偶尔犹豫；因为你曾有过回忆，所以你会有所保留；因为你曾有过回忆，所以你渐渐变得迟疑。(Because there had been recalled, you will fear because there had been recalled, so you will occasionally hesitate because there had been recalled, so you will be retained because you have had memories, so youbecome more and more hesitant.)

关于麦克风阵列信号处理，根据声波传达理论，利用多个麦克风收集的信号可以将某一方向传来的声音增强或抑制，通过改变权值来改变某一方向的信号的接收强弱(About microphone array signal processing , according to the theory of sound waves to communicate using signals multiple microphones to collect a certain direction came the sound can be enhanced or inhibited by changing the weights to change the receive signal strength in a certain direction )

MATLAB 牛顿下山法的一个小程序，原理就不详细说了。因牛顿迭代法受初值选取的限制，为防止迭代发散，对迭代过程再附加一项要求:|f(x(k+1))|<|f(x(k))|,将牛顿法迭代的结果:x(k+1) =x(k)-f(x(k))/f (x(k))和前一近似值x(k)适当加权平均做为新的改进值:x(k+1)=u*x(k+1) +(1-u)*x(k),其中u(0<> 迭代时u取1开始，逐次减半计算，直至附加要求符合为止。实例计算中x(k)=x(0)不变，只更新u和x(k+1)，直至:|f(x(k+1))|<|f(x(k))|（即|f(x(1))|<|f(x(0))|)，然后更新下山因子为u=1,继续以牛顿法迭代。(MATLAB Newton-down a small program, the principle is not explained in detail. Newton iteration by the initial value of the selected limit, in order to prevent additional iterative divergence, the iterative process a request: | f (x (k+1)) | < | f (x (k)) | Newton iteration Results: x (k+1) ' = X (k)-f (x (k))/f' (x (k)) and a previous approximation x (k), appropriately weighted average as a new improved value: x (k+1 ) = u* x (k+1) ' + (1-u)* x (k), where u (0 < u> iteration take successive calculated at 50 until the additional requirements found so far. examples of calculation of X ( k) = x (0) unchanged profile u and x (k+1, hungry) until: | f (x (k+1)) | < | f (x (k)) | (i.e. | f (x (1)) | < | f (x (0)) |), then profile downhill factor for u = 1, to continue to Newton iteration.)

程序完成的功能是用lms算法对声音去噪声。运行后先会听到canon的一小段无噪声的音乐，然后会听到加了噪声后的效果，最后会听到用lms去噪之后的声效。(Program to complete the function with lms algorithm to noise sound. Run first hear the canon of short noise-free music, plus the effect of noise will then hear, and finally will hear the sound denoising with lms.)

针对谐波检测问题，比较几种常用谐波检测方法，总结出各自的适用条件。结合经验模态分解理论和总体平均经验模态分解(empirical mode decomposition，EEMD)算法，提出基于EEMD的谐波检测方法。(For harmonic detection problem, comparing several common harmonic detection method, summed up their applicable conditions. Combining theoretical and empirical mode decomposition overall average empirical mode decomposition (empirical mode decomposition, EEMD) algorithm, based on harmonic detection method EEMD.)
