说明：  对于结构分析中的下降段，计算出荷载下降至最大荷载0.85倍时的位移值，然后计算该位移值与最大荷载对应位移值得比值，即延性系数。(Therefore, the early-age cracking and splitting were avoided and the steel components could fully develop its strength, which resulted in a higher peak load and stiffness.)

说明：  点击按钮出现弹框的效果，界面已经美化可以自己开发(Click on the pop-up effect)

说明：  调试专用 RJ45短路环 自测试通过！！！！(RJ45 Short Circuit Ring)

首次上传，说明内容。我想学习一下给网站的资料，日后编得代码，再上传补上。抱歉！-From the first time to illustrate the content. I want to learn about the information to the site, the future provision of a code, and then upload onto the list. Sorry!

说明：  相控触发脉冲电路+整流调压电路+Buck斩波电路+逆变，Buck使用了电流电压双闭环反馈控制，采用Simulink仿真(Closed Loop Control of Buck Chopper Circuit)

说明：  易买网项目源码，全部功能都实现。欢迎大家下载！(Easy to buy network project source code, all functions are realized)

飞机起落架摆震模型，simulink建模，仿真参数依照747-800的参数(aircraft landing gear shimmy)

关于课件 好多种结构的算法 等等 大家自己看吧 -good courseware on a variety of algorithms, etc. we all Look here

echart离线查看api，在没有互联网的情况下，离线查看官网api，帮助开发者开发示例(Echart view the API offline, and in the absence of the internet, view the official API offline to help developers develop examples.)
