找到 MySQLWorkbench的安装目录下的 datamain_menu.xml 这个文件并改名，再将此文件中的main_menu.xml复制进去，可完成部分汉化。(Find the file datamain_menu.xml in the installation directory of MySQL Workbench and rename it, then copy the main_menu.xml in the file.)

用Wilson方法计算结构动力反应(无阻尼)-Wilson calculated using the structure of dynamic response (without damping)

pscad搭建的含分布式电源的单馈线ieee4节点、13节点和34节点算例，共7个源文件(pscad build single feeder ieee4 node containing distributed power of 13 nodes, 34 nodes example, a total of seven source files)

说明：  LPC1768adc和uCOS加一起,主要是用一个adc采集信号然后通过串口发送(LPC1768adc and uCOS are added together, mainly using an ADC to collect signals and send them through serial port.)

交互式画图的应用例子! 希望可以供大家学习-interactive drawing application example! Hope everyone can learn

VC++窗体框架可折叠展开+Tree树菜单视图例子，这个框架可随意拉动，变换窗口大小，另外左侧框架中的树形菜单也是大家平时经常用到的编程技巧，树形菜单的实用性非常强，另外里面还有一些其它的技巧，都是对学习VC++界面设计会有所帮助。

为简单起见，我们对舰船甲板模型进行了简化，根据Brretschneider波普的方法，将无人直升机在降落台所在平面上的投影点距离海平面的高度视为无人直升机追踪的甲板高度变化。(For simplicity, we simplified the warship deck model. According to the Brretschneider Pope method, the height of the projection point from the plane of the landing platform to the sea level was regarded as the change of the deck height of the UAV.)
