本DTW的语音识别算法是日本学者sakoe提出的，这种方法比itkura的要好，但本算法没使用到加权，方法简单了，以后再图改进(The DTW recognition algorithm is proposed by Japanese scholars sakoe, this method is better than itkura, but did not use this method to the weighted method is simple, and later plans to improve)

Introduction to Extended Kalman Filter

利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)

采用Newmarke线性加速度法由加速度时程求位移、速度、加速度的反应谱及动力放大系数(β)谱(The response spectrum and dynamic magnification factor (beta) spectrum of displacement, velocity, acceleration are obtained by using newmarke linear acceleration method)
