钢结构断面绘制

Cytoscape的使用方法，如何正确使用复杂网络绘图工具的使用方法(Cytoscape to use, how to properly use the complex network to use the drawing tools)

MFC做的画图软件 只能画直线 还有待改进 适合初学者 看看(MFC do draw a straight line drawing software can be improved for beginners look)

说明：  利用PSCAD搭建的单相MMC系统，其中的子模块采用理想电压源与IGBT构成，成功仿真出阶梯波形(PSCAD built using MMC system, single-phase, in which sub-modules form an ideal voltage source with IGBT, successful simulation of the step waveform)

DDA算法画直线，可以实现在网格下逐点画直线。(DDA algorithm for drawing straight lines, can be achieved in a grid-by drawing straight line.)

说明：  问题的提出：根据“心”形曲线的数学参数方程，绘制曲线并输出屏幕。在各坐标点处循环显示“LOVE”的各字母。 编程思路：“心”形曲线的数学参数方程为: (Of the problem: According to the &quot heart&quot -shaped mathematical curve parameter equation, drawing curves and output screen. Coordinates of points in the cycle show &quot LOVE&quot in the letter. Programming idea: &quot heart&quot -shaped mathematical curve parameter equation:)

改进的Bresenham算法，用visual c++ 实现(Improved Bresenham algorithm, using visual c++ achieve)

GDI source code. You can learn drawing in first

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

基于PSCAD 4.5搭建的IEEE 第一标准测试模型，可以用于次同步振荡的研究。(The first IEEE standard test models built based on PSCAD 4.5 can be used to study sub-synchronous oscillations.)

MFC画图板，可以画一些基本图形，如直线，椭圆，扇形，矩形，弦形，三角形。 可以保存为BMP的文件(MFC drawing board, you can draw some basic graphics, such as line, ellipse, sector, rectangle, string, triangle. Files that can be saved as BMP)
