说明：  Coordinate 组件库可被用于 坐标的变换 和 坐标系统的转换 等。 组件库又分成了两个子库：2D 和 3D，其中 2D 库用于平面坐标的处理，3D 库用于空间坐标的处理。(Coordinate component library can be used for Coordinate transformation and Coordinate system transformation. The component library is further divided into two sub-libraries: 2D and 3D. 2D library is used for processing plane coordinates and 3D library is used for processing space coordinates.)

说明：  SLIC算法是simple linear iterative cluster的简称，该算法用来生成超像素（superpixel） 算法步骤： 已知一副图像大小M*N,可以从RGB空间转换为LAB空间，LAB颜色空间表现的颜色更全面 假如预定义参数K，K为预生成的超像素数量，即预计将M*N大小的图像(像素数目即为M*N)分隔为K个超像素块，每个超像素块范围大小包含[（M*N）/K]个像素 假设每个超像素区域长和宽都均匀分布的话，那么每个超像素块的长和宽均可定义为S，S=sqrt(M*N/K) 遍历操作，将每个像素块的中心点的坐标(x,y)及其lab的值保存起来，加入到事先定义好的集合中(Algorithmic steps: Given the size of an image M*N, it can be converted from RGB space to LAB space, and the color space of LAB is more comprehensive. If the predefined parameter K, K is the number of pre-generated super-pixels, i.e., the image of M*N size (the number of pixels is M*N) is expected to be divided into K super-pixel blocks, each of which contains [(M*N)/K] pixels. Assuming that the length and width of each super-pixel region are evenly distributed, the length and width of each super-pixel block can be defined as S, S = sqrt (M*N/K). The traversal operation saves the coordinates (x, y) and lab values of the central points of each pixel block and adds them to a pre-defined set.)

一款flash制作的弹钢琴游戏，可以用鼠标点击，或者键盘按键来进行弹奏。-A flash game produced by playing the piano, you can use mouse clicks or keyboard keys to be played.

基于51单片机和8位ADC的数字电压表，可测量0-5V电压，程序用C语言编写。(Based on MCU and 8 bit AD C digital voltmeter, 0-5V voltage can be measured. The program is written in C language.)

说明：  InSAR数据滤波方法,包括中值滤波，均值滤波，圆周期滤波等(InSAR data filtering methods, including median filtering, mean filtering, circular periodic filtering, etc.)

VB实现三维模型渲染程序，纯VB代码实现，没有用到第三方支持库，编译后即可看到三维空间线段和茶壶三维旋转变化效果，透视感极强，看上去挺不错。

说明：  9电平MMC逆变器，开环控制，明显可以看出9电平逆变，采用载波移相调制(9-level MMC Inverter, Open-loop)

说明：  jQThumb是一款基于jQuery的缩略图插件，它能够很方便的制(Introduction to the script jQuery image zooming and inserting background image effect)
