说明：  恒压变频供水，实现供水的恒压变频，可以恒压供水，并且可以通过变频器节能(niceConstant voltage and frequency conversion water supply can realize constant voltage and frequency conversion of water supply, water supply can be constant pressure, and energy saving can be achieved through frequency converter.)

说明：  地震工程用于生成匹配设计谱的时域调整记录(Time domain adjustment record for matching design spectrum generation in seismic engineering)

说明：  维纳滤波算法，可以实现对语音信号的降噪，效果还可以(Wiener filtering algorithm, it can achieve noise reduction on speech signals)

常用的颜色色差计算程序，输入颜色的三刺激值，得到色差值。(Commonly used color difference calculation program, enter the color of the three stimulus value, to get color difference value.)

算法交易，统计套利，配对交易python代码实现(Algorithm trading, statistical arbitrage, pair trading, Python implementation)

说明：  在R语言中有根据矩阵绘制色块图的程序，可以用于绘制相关系数矩阵图，用丰富的颜色和形状形象的展示矩阵元素值的大小。今天介绍的是如何用matlab绘制矩阵色块图。(In R language, there is a program to draw color block graph according to matrix, which can be used to draw correlation coefficient matrix graph and show the size of matrix element value with rich color and shape image. How to draw matrix color block diagram with MATLAB is introduced today.)

说明：  用于计算多普勒频移的函数，MATLAB语言，挺好用。(The function for calculating Doppler frequency shift, MATLAB language, is very useful.)

说明：  Fourier Ptychography是一种首先开发用于显微镜的成像技术。该技术首先收集感兴趣的显微样品的一系列图像。从相干光源（通常从LED阵列）以不同的照明角度获取每个图像。然后，使用迭代相位检索算法将获取的图像集组合为最终的高分辨率图像，该图像可以包含多达十亿个像素（千兆像素）。该技术还提供了非干涉相位图像和近波长衍射极限分辨率。(Fourier Ptychography is an imaging technique first developed for use in microscopes. The technique first collects a series of images of a microscopic sample of interest. Each image is acquired under a different angle of illumination from a coherent light source (typically from an array of LEDs). The acquired image set is then combined using an iterative phase retrieval algorithm into a final high-resolution image that can contain up to a billion pixels (a gigapixel). The technique also provides a non-interferometric phase image and near wavelength diffraction-limited resolution.)

不仅用于潮位调和分析和预报，还能对潮流进行准调和分析，包含两种功能，一次性解决潮汐问题，是目前为数不多的程序包。(Not only for tidal level harmonic analysis and forecasting, but also the tidal current analysis, including two functions, one-time solution to the tidal problem, is currently a precious packages.)
