微信功能实现通信机制沟通你我他.在你我他之间架起沟通的桥梁(Micro-channel communication mechanism to achieve functional communication you and me. Between you and me, he acted as bridges)

objective-c textfield 下拉菜单实现(objective-c textfield drop-down menu to achieve)

说明：  XML解析，功能很强大，大家可以参照下，肯定会有用(XML Parser，powerful functions，you can learn something from it easily.It must be useful to you!)

很实用的IPHONE完美实现自定义软键盘(IPHONE perfect realization of very useful custom keyboard)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

说明：  ST分段控制的iOS，精选ios编程学习源码，很好的参考资料。(ST segment control of iOS, ios programming learning source selection, a good reference.)

matlab实现文件读取，波形处理，小波变换，文件保存。(use matlabe to read and write files, to process wave and to save files)

STM8L101F3数码管显示_追梦效果_跑马灯——模拟SPI比如：数码管显示可以从0跑到9，也可以从9跑到0；可以在数码管外跑圈圈等等!实用于做实验等等

MATLAB实现潮流计算的程序基本使用牛顿拉夫逊法进行计算(Matlab load flow)
