用于abaqus软件的单元删除，是应用在abaqus软件后处理时，删除已经失效的单元(Unit for abaqus software delete application abaqus software processing, the unit has failed to delete)

用stc12作为主控芯片，结合1602进行显示，最终实现万年历的功能，包括显示年、月、日、星期、时、分、秒等等，而1602的显示这是利用逐个字符的显示方法，相信对于初学者而言，这是一份学习的好代码，当然也是一个使用的电子产品

分支定界法（branch and bound）是一种求解整数规划问题的最常用算法。这种方法不但可以求解纯整数规划，还可以求解混合整数规划问题。分支定界法是一种搜索与迭代的方法，选择不同的分支变量和子问题进行分支。(Branch and bound (branch and bound) is one of the most commonly used algorithms for integer programming problems. This method can not only solve pure integer programming, but also solve mixed integer programming problems. Branch and bound is a search and iterative method, which selects different branch variables and sub problems to branch.)

这是用flash制作的三维立体动画，请大家学习和指导。-This is the flash produced three-dimensional animation, we learn, and guidance.

程序功能很多，还可以摆残局。棋力大约在中间水平，只比棋隐、雷霆等软件差些。 被改写了部分代码，速度比原程序约快2倍，不过有时候搜索的点反而多，本想再加入简单开局库，可没时间且要改的内容很多。由于作者设计的数据结构、估值函数的缺陷，程序中残局问题很多，比如单兵、单马电脑不知道如何赢孤将！！ -many functions of the program can also put the whole mess. Lindsborg about in the middle level, a game than implicit, Thunder software badly. Some were rewritten code, faster than the original procedure about two times faster, but sometimes the search point, more than the simple wish to join the first basement, which could not be changed to a great many. As the author of the data structure design, valuation function defects, procedures mess many problems, such as one-man, Mr Ma computers do not know how to win alone! !
