vb编写的XML入门程序-the accidence program of XML programming by vb

用于更改系统桌面背景，虽然微软本身有一个动态库提供了这个功能，但是这个库本身系统不带。因此用Delphi编写了这个程序，用于设置自动更换桌面背景-Change the system for the desktop background, while Microsoft itself has a dynamic library provides this functionality, but the library system does not take itself. Delphi therefore prepared to use this procedure for the automatic replacement of desktop background

主要用来画地球物理勘探专业的测深（瞬变电磁，大地电磁，激发极化测深，复频激电，甚低频等等）电阻率的曲线类型图；操作简便，易于观察，可以生成矢量化图片与surfer，grapher等软件进行交换处理。

图11是原图，可得到是预处理之后的二值化化图像，可以看出图中主要有三条裂纹，应用此代码可以检测出图中存在的裂纹，并进行标记。主要工作为应用数字图像处理技术对裂缝图像进行实时 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报

很常用的3D框架，对于初学的朋友用处很大，只能做为参考，不能做商业用途-3D framework is very commonly used, for the use of a great friend of learning, can only be used as reference, can not do commercial purposes

A*算法属于一种启发式搜索。它扩展结点的次序类似于广度优先搜索，但不同的是每生成一个子结点需要计算估价函数F，以估算起始结点到该结点的代价及它到达目标结点的代价的和；每当扩展结点时，总是在所有待扩展结点中选择具有最小F值的结点作为扩展对象，以便使搜索尽量沿最有希望的方向进行。 -A* algorithm is a heuristic search. It extended node in the order of priority similar to the breadth of search, but in every generation is a sub-node calculated valuation function F, to estimate initial node to the node, the price and it arrived at the target node, and the price; Whenever expansion node, the question has always extended to all nodes with the smallest choosing F value of the node as expansion targets, in order to search as far as possible along the most promising direction.
