使用C#实现的delaunay三角网生成算法。使用说明：运行后在窗口中单击鼠标添加样采样点，当采样点大于等于3时自动生成delaunay三角网；点击工具栏上的按钮可以显示每个三角形的外心。

利用TDN86/88实验系统模拟交通信号灯的实时控制和管理，具体要求： 1、先是车绿灯亮，人行道红灯亮10秒钟； 2、红绿灯切换前开始闪烁，每秒闪烁一次，持续6秒钟； 3、红绿灯切换,车红灯亮，人行道绿灯亮10秒钟； 4、红绿灯切换前开始闪烁，每秒闪烁一次，持续6秒钟； 5、如此循环重复；文档+程序！！！

高性能PCB 的SI/PI 和EMI/EMC 仿真设计ANSOFa subsidiary efIPCB信号完整性甩源完整性和EM分析培训手册是瞬时,也就是瞬态情况下的阻抗:++++++++这个阻抗是传输线本身的物理结构决定的,一般会设计成50欧姆,这是在微波的发展过程中逐渐形成的。射频电缆特性阻抗在70多欧姆左右吋,传输损耗最小;在30多欧姆吋,承受功率最大。两者综合,选择50欧姆,同时照呗到两种性能,所以就选择了50欧姆作为一个标准。如果外接的阻抗冋特征阻抗不一致,就会产生反射2.3反射系数和信号反射当传输线的传播的信号到达某个阻抗不连续的节点时,信号会发生反射,就像水流通过不同∏径的管道接∏时,水面产生波动样。根据反射电压和入射电压的比值,可以定义传输线上的反射系数F。R-Z.R,+z当负载阻抗大于输入阻抗,反射系数r>0,反射信号与入射信号同向叠加:当负载阻抗小于输入阻抗,反射系数r pour manager中进行 Plane connect和 Hatch的操作,如下图所示:u Pour ManagerFlood Hatch (lane Connect lInternalPlane1elect点Internalplant1 Confirm Connect O perationStart close[邮卫。[H8PCB信号完整性/电源完整性和EM分析培训手册ANSOFTsubsIdiary ef ANRY, las,haI■u Pour ManagerFlood Hatch) lane Connect IHatch Mode8Hach点Fast hatch匚cx匚se.匚世p接下来,需要在菜单的too-> option->Sp| it/Mixed plane设置中,对 Save to pcb file栏选择 All plane data选项。如下图所示:optionsDrafting Grids < split / Mixed Plene>L Die Component via PatterSave to pcB filtMixed plane display○ Plane polygon outline○ Plane polygon outlines斗 plane data→ed plane dating radius:0.00凸ar ate gap:日Automatic actionsRvIRCreate cutouts around embedded platLanHelp设置好此项后,在菜单中运行File-> Export,选择*.asc文件的路径和名称后,弹出以下对话框:
