vb6.0的验证码处理，在去除干扰点时，采用中值滤波是一种不错的方法，中值滤波法是一种非线性平滑技术，它将每一像素点的灰度值设置为该点某邻域窗口内的所有像素点灰度值的中值。中值滤波的实现方法

TLC2543的中文简介,附有汇编操作,TLC2543是德州仪器公司生产的12位开关电容型逐次逼近模数转换器，它具有三个控制输入端，采用简单的3线SPI串行接口可方便地与微机进行连接，是12位数据采集系统的最佳选择器件之一。本文介绍了该芯片的功能、时序，并给出了8051单片机的接口电路。-TLC2543 briefed the Chinese, with the compilation operation, TLC2543 is by TI Switched-Capacitor 12-successive approximation ADC. it has three control input, a simple three-wire SPI serial interface can be easily connected with the computer, yes 12 Data Acquisition System devices to choose the best one. This paper introduces the chip functional, timing, and gives the 8051 interface circuit.

说明：  模块化多电平换流器(modular multilevelconverter MMC)已成为柔性直流输电系统的首选换流器拓扑。我国已建成的上海南汇柔性直流工程、南澳三端柔性直流工程、舟山五端柔性直流输电工程以及正在建设中的厦门柔性直流工程都采用MMC结构。国际上SIEMENS已建成的美国跨湾工程(Trans Bay Cable Project TBC)和法国一西班牙联网工程(INELFE工程))都采用MMC结构。同时，ABB公司提出了一种级联两电平结构(cascaded two level CTL)，其本质仍为MMC，并且ABB后续建设的数项柔性直流工程都采用CTL结构。因此，MMC已由最初的低压、小容量示范工程向高电压、大容量方向快速发展，展现出很好的发展前景。(Modular multilevel converter (MMC) was first proposed and patented by Professor R. Marquardt in 2001. It consists of several sub modules (SM) with the same structure. The sub module structure can be divided into three types: half H-bridge, full H-bridge and double clamp sub module. Modular multilevel converter (MMC) has shown a very important engineering application prospect.)
