说明：  非常有用的资料，C#源码,能够直接导入DXF文件，并对DXF文件分析是圆、线，轮廓等形状，并对形状进行分析，可以直接生成G代码或者点位信息。自己可以拿点位信息再做处理。(Very useful information, C # source code, can directly import DXF file, and DXF file analysis is circular, line, contour and other shapes, and shape analysis, can directly generate G code or point information. I can take the point information and then do the processing.)

Finite difference methods: Spatial discretization (3) Temporal discretization (2) Convergence, Consistency, Stability (2) Solution of PDEs require spatial and temporal discretization Typically, the spatially-discretized domain is called the grid The PDE (originally on a continuous domain) is solved on a discrete set of grid points Typically, the PDE is reduced to a set of algebraic equations (that might or might not involve matrix inversion) Types of grids: Structured grid Unstructured grid Hybrid grids

说明：  VB采用三层架构的CRM客户关系管理系统，基于Access数据库。是一个电脑公司以前用过的，因些功能上可以满足中小型公司使用，只是部分模块是定制的，有的可能不太实用，从界面上来说，像是一挺专业的程序。 　　本系统用到有yfDNetMenu.ocx、ManageClient.dll控件，已打包，初次运行请运行reg.bat以及重新添加两控件引用，否则报错。(VB three-tier architecture, CRM customer relationship management system, based on Access database. Is a computer firm had been used previously, because these functions satisfy the medium and small companies to use only part of the module is customized, and some may not be practical, from the interface point of view, like a professional program. This system uses a yfDNetMenu.ocx, ManageClient.dll controls, has been packaged, the initial run reg.bat run and re-add the reference to two controls, otherwise Baocuo.)

通过均线和MACD来判断未来趋势，然后自动下单，只能抓取第二波和第三波趋势，第一波因为价格变动不一定正确，所以只抓取第二波和第三波。(The future trend is judged by the equalization and MACD, and then the second and third wave trends can only be captured. The first wave is not necessarily correct because of the price change, so only second and third waves are captured.)

自用java编制了一个能在局域网中实现internet一样的聊天功能-with java,working out a program whichcan achieve the chat fuction as internet in the LAN.

说明：  对信号进行三层变换，得到小波系数d和逼近系数a，得出各频段的能量。(The wavelet coefficient D and approximation coefficient a are obtained by three-level transformation of the signal, and the energy of each frequency band is obtained.)
