主要应用于对地震信号，数据的去噪，构造了地震数据然后去噪对比结果，(It is mainly used to denoise seismic signals and data, construct seismic data and then denoise the contrast results.)

说明：  利用Matlab生成二维随机裂隙，控制裂隙密度、倾向、迹长分布函数、均值、标准差(Using MATLAB to generate two-dimensional stochastic fractures and control the density, tendency, trace length distribution function, mean and standard deviation of fractures)

提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。(presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness.)

利用matlab实现雷达波位排列，轻松实现波束相扫(radar beam set by matlab, )

自抗扰控制器自写，调节参数可用。含TD跟踪微分器，NLSEF非线性反馈律，ESO扩张状态观测器(Self rejection controller is self written, and the adjustment parameters are available)
