用matlab语言编写了一个GUI截面，通过该界面可以实现图像的傅立叶变换，反傅里叶变换，高低通滤波，以及把黑白图像转化成灰度图像等功能。(Matlab language with a GUI section, the interface can be achieved through the Fourier transform of the image, anti-Fourier transform, high and low pass filter, and the black and white image into gray image and other functions.)

为研究局部阴影效应对光伏发电系统的影响，首先建立了光伏阵列工程数学模型，分析局部阴影条件下光伏阵列的输出特性。为了便于工程分析，该文利用PVSYST软件分析比较单晶硅、多晶硅和薄膜电池等3种不同材料光伏电池在局部阴影条件卜的输出功率，为工程应用提供了良好的指导作用。最后提出了几种提高光伏阵列抗局部阴影能力的措施厂 (To investigate the effect of local shading effects on photovoltaic systems, photovoltaic array project was first established mathematical model to analyze the output characteristics under conditions of partial shading of the PV array. In order to facilitate engineering analysis, this paper use PVSYST software analysis and comparison monocrystalline, polycrystalline and thin film batteries, photovoltaic cells of three different materials in partial shade conditions Bu output power for engineering applications provide a good guide. Finally, several photovoltaic arrays to improve the ability to measure resistance to partial shade plant)
