通过一个实例来介绍在当前高端三维CAD软件上做二次开发的一般方法，整个功能中实现了对零件的分模处理，通过调用NX的二次开发接口，以及对应的c函数，实现零件的选择，菜单生成，菜单对对话框的调用，以及如何在NX的二次开发中调用MFC的对话框，实现对已有NX二次开发界面的功能扩充。

These three articles involves the combination of wavelet and MCTF. MCTF means motion-compensated-time-filter. It makes wavelet transform more popular because of the high compression efficiency.

摘要 : 在 MAT LAB环境下利用语音工具箱 Voice Box实现基于连续概率密度隐含马尔科夫模型的汉语语音识别系统。在 实时录音的情况下 , 利用该语音识别系统 , 不同的人对 20条 2～8个字的语音命令进行识别 , 准确率可达到 95 ％ , 识别时间 115～3 s , 实现了小词汇量连续语音的非特定人的实时识别。-Abstract: In the circumstances the use of MAT LAB toolbox Voice Box Voice realize implied probability density based on continuous Markov model of Chinese speech recognition system. In real-time recording, the use of the voice recognition systems, different people on the 20 2 ~ 8-word voice command recognition accuracy rate can reach 95 percent, identify the time 115 ~ 3 s, the realization of a small vocabulary continuous voice of the non-specific real-time identification of people.

欢迎使用“PLC串口通信调试” 本软件主要用于PLC(或单片机)与计算机的串口通信调试。软件根据目前PLC常用的多种串行通信协议的特点设计，数据的输入、组织和显示方式灵活多样，便于使用和观察调试。 在编制计算机与PLC的串口通信程序时，由于计算机和可编程设备双方均需编制通信程序，调试时往往不知道是哪一方的程序出了问题。可以使用本软件调试PLC一侧的程序，调试正确后再调试计算机侧的程序。本软件为PLC串口通信程序的调试提供了便利。-Welcome to "PLC serial communications debugging" This software mainly used for PLC (or single-chip) and the computer s serial communication debugging. According to the current PLC software for a variety of common characteristics of serial communication protocol design, data input, organize, and display flexible, easy-to-use debugging and observation. In the preparation of the computer s serial communication with the PLC program, computers and programmable devices as a result of both procedures require the preparation of communication, debugging often do not know which side the procedure is a problem. Can use the software side of the PLC program debugging, testing the right side after the debugging of computer procedures. The software for the PLC seria
