C# 编写的监控Windows剪贴板的小程序，这里面有计时器的相关创建方法，设置计时器间隔为1000毫秒并启动计时器，监控剪切板并判断剪贴板中是否存在文本数据，然后将剪贴板中的内容显示在richTextBox1控件中。下面的代码是本程序的核心： 　　private void Frm_Main_Load(object sender, EventArgs e) 　　{ 　　 timer1.Interval = 1000;//设置计时器间隔为1000毫秒 　　 timer1.Start();//启动计时器 　　} 　　private void timer1_Tick(object sender, EventArgs e) 　　{ 　　 if (Clipboard.ContainsText())//判断剪贴板中是否存在文本数据 　　 richTextBox1.Text = Clipboard.GetText();//将剪贴板中的内容显示在richTextBox1控件中 　　}

代码用来计算粗糙面的后向散射，同极化 VV, HH。平面波入射。用的SPM方法，适用于RMS height比较小的粗糙面。(rough surface scattering for small RMS height)

VB拼图游戏 可以自己加载任意图片 -VB can load arbitrary puzzle picture

可以测量低频的高电平时间，如果需要测高频，可以更改定时器的频率，本程序使用的ACLK（32768hz)(It can measure the high level time of low frequency. If it needs to measure high frequency, it can change the frequency of the timer. ACLK (32768 hz) is used in this program.)

说明：  学生成绩管理 可以对输入各科成绩分数(Student performance management can enter various accomplishments Score)

编号为1-52张牌，正面向上，从第2张开始，以2为基数，是2的倍数的牌翻一次，直到最后一张牌；然后，从第3张开始，以3为基数，是3的倍数的牌翻一次，直到最后一张牌；然后…从第4张开始，以4为基数，是4的倍数的牌翻一次， 直到最后一张牌；...再依次5的倍数的牌翻一次，6的，7的 直到 以52为基数的 翻过，输出：这时正面向上的牌有哪些？-No. 1-52 card in a positive, progressive, from the first two, with two as the base, 2 is a multiple of the license over time, until finally a license; Then, from the first three starting with three to the base, 3 is a multiple of the license over time, until finally a license; Then ... from the first four starting to four as the base, 4 is a multiple of the license over time, until finally a license; ... followed by the five multiples of the licensing repotted once, 6, 7 to 52 until the base of the turn, the output : At this time positive signs of upward What?
