小波包分析提取振动信号中的特征频率，分析了该信号的时域、频域、倒谱，循环谱等,有井曲线作为输入可计算其地震波的衰减。( Wavelet packet analysis to extract vibration signal characteristic frequency, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. There is a well attenuation curve as input to calculate its seismic waves.)

标准的电源插口尺寸图，很难找的，没有封装可以自己根据尺寸画。(Standard power socket size chart, it is difficult to find, no package can draw their own according to size.)

基本的程序设计入门，学习，对于新手是很好的入门教程。(The basic program design entry, for beginners learning, is a very good tutorial)

UML包括事物、关系、图、扩展机制。 （1）事物 结构：类、接口、构件、节点等等。 行为：交互（消息）、状态等等。 分组：包、子系统等等。 注释：注释。 （2）关系 依赖、关联（聚合、组合）、泛化、实现。 （3）图 用例图、交互图（顺序图、协作图）、类图、活动图、状态图等等。 （4）扩展机制(UML includes things, relation, graph, expansion mechanism. ( 1). Structure: class, interface, components and joints, etc.. Behavior: Interactive ( News ), the state and so on. Packet: packet, subsystem and so on. Annotation: annotations. ( 2) relationship Dependent, Association ( polymerization, composite ), generalization, to achieve. ( 3) map Use case diagram, diagram ( sequence diagram, collaboration diagram, class diagram, activity diagram ), state diagram and so on. ( 4) extension mechanism)

计算机接口技术系列 Visual C++串口通信技术与工程实践 在编译本章程序后，请将winio.dll、winio.vxd和winio.sys文件复制到可执行文件所在目录下, 否则WinIo库初始化函数initializeWinIO调用将会失败。(computer interface technology Series Visual C serial communication technology and engineering practice in compiling this chapter procedures, I would be grateful if winio.dll. winio.vxd winio.sys reproduction of documents and executable files to the directory, Otherwise WinIo initializeWinIO the initialization function call will fail.)

本文从基于数据库的知识发现开始，较系统全面地介绍了KDD、数据挖掘都基本概念，并研究了数据挖掘所采用都技术方法和应用领域：在现有研究工作的基础上，提出用连续量代替离散量来表示客体的思想，同时采用积分面积来表示两个客体之间都距离，并对客体进行分类。利用上述方法对学生都数据进行挖掘，得到了一些有用的结论，从而指导学校都教学工作。(Based on the knowledge discovety in database this paper presents a introduction of KDD,an concept of data mining and a research into the technical approach and fields of application of data mining.Based on the present research work,this paper is devoted to the idea of presenting the segregation amount by using the whole amount.Integral square is adopted to indicated the distance between two units.And the above-stated method is used to analyze the students data.And some useful information is thus obtained.So it is instructive to teaching at colleges.)

VC小技巧15个，都很实用，请大家试试看。(VC tips 15, are useful, please give it a try.)

不是代码，仅有的一点编程资料，希望可以与大家分享，很好很实用的资料(Not a code, the little programming information, hoping to share with you, very good very practical information)

说明：  该程序是一个完整的画图板实现功能，有直线，矩形，椭圆，文本和图像的处理功能。(The program is a complete drawing board to achieve function, there is a straight line, rectangle, ellipse, text and image processing capabilities.)
