需要一个放有若干图片的文件夹，图片的文件名还需要提供一些信息，如“计61班.jpg”之类，具体格式可以修改源代码。然后显示图片让参与者猜是哪个班的。为系里男生节编写的一个简单的GUI程序(Need a put several pictures folder, pictures of the file name also need to provide some information, such as "(61 class. JPG," and so on, and the specific format can make changes to the source code. And then display picture participants had to guess which class is. For the day of a boy to write simple GUI program)

说明：  一套非常漂亮的图片站程序，以前本人用过的，而且利于排名！(A very beautiful picture at stations, previously I used, but also helps to rank!)

生成一个正弦信号，并加入白噪声，得到正弦信号以及白噪声的混合信号，通过低通滤波器对白噪声进行处理(generate a sinusoidal signal, and add white noise, sinusoidal signal to be white noise and mixed-signal, through low-pass filter white noise processing)

空间谱估计music 谱估计方法,估计信号参数(Spatial spectrum estimation music spectrum estimation methods, estimates signal parameters)

多个电力电子、电机仿真模型。是重要的学习电力电子simulink 仿真的素材，权威教材，内容较多，分成上下两集,这个是上(useful simulink modles for leaners)
