VB有限元程序，利用三角形单元来计算静力荷载

对任意给定的二叉树（顶点数自定）建立它的二叉链表存贮结构，并利用栈的五种基本运算（置空栈、进栈、出栈、取栈顶元素、判栈空）实现二叉树的先序、中序、后序三种周游，输出三种周游的结果。- To wilfully assigns two forks the tree (to go against points from to decide) establishes it two to fork the chain table storage structure, and (sets at spatial stack after the stack five kind of fundamental operations, enters stack, sends out of the warehouse, takes stack top element, sentences stack to be spatial) realizes two forks the tree first the foreword, center the foreword, the foreword three kinds travels around, outputs the result which three kinds travels around.

Householder变换是基本的数学变换之一。其作用是将被变换向量映射成相同模的其它向量。其应用之一是QR分解。-Householder transform is one of the basic mathematical transform. Its role is to transform vectors will be mapped into the same mold of the other vector. One of its applications QR decomposition.

rsa&md5 公钥和私钥就是从两个文件PublicKey.xml、PrivateKey.xml中读取出来，相当于是现实中的指定公钥和私钥；再验证时我为了方便直接验证的A计算出的HASH码，现实中应该是由B重新计算出文件M的HASH码-ras&md5
