随机抽取
第一个编程题,首先会用到Timer对五个随机数转动的时间间隔进行控制。然后还要将事件与Enter键进行关联,程序实现了Enter键控制转动的开始和结束的功能。最后还要连接数据库,以便于根据选中的编号从数据库中调出对应的姓名并显示在界面上。第二个编程题中涉及的知识更全面一点,包括资源管理器浏览方式的实现、将Excel表格中的内容导入DataGridView控件中、找出符合题意的抽取方法、将DataGridView控件中的内容导出到Excel表格中并保存等等。但是最关键的还是简单、实用的抽取方法。

一个平行的脉冲的简单模拟
This simple simulation of a pulse traveling down a parallel-plate guide makes a handy test code for initial experiments with boundary conditions. ToyFDTD3 adds some simple features to ToyFDTD1: A PMC boundary condition, a sinusoidal pulse source, and output tracking a single point in the mesh. Released 15 June 1999.
