三维矢量有限元-矩量法电磁场分析程序。 EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.(Three-dimensional vector finite element- MoM electromagnetic field analysis program.

单链表中的数据元素含有三种字符（字母、数字、其他字符），算法实现构造三个循环链表，是每个循环链表中只含有同一类字符，且利用原表中的结点空间作为这三个表的结点空间。(Singly linked lists of data element contains three characters (letters, Numbers and other characters), the algorithm constructs three circular linked list, each cycle list contains only the same type of character, and make use of the primary node space in a table as a node of the three table space.)

基于视频理解的人群密度模型的建立。利用图像像素密度与人群密度之间的关系、特征提取法在抽取群体轮廓时的矩不变特性，建立多分辨率条件下人群空间域密度逻辑模型与人群时间域轨迹逻辑模型，通过对两种模型进行自适应训练，逐步形成“时空”人群趋势变化逻辑模型

在VS2005下开发的，根据数据样本绘制直方图，因此获得初步的概率分布。-Developed in VS2005, according to data drawn sample histogram and so was the initial probability distribution.

本代码是句C++代码编写的，实现了二维波动方程正演，三维波动方程正演，一阶形式下的波动方程正演，并能输出快照文件和记录文件（seg-y格式），也能导入数度模型（seg-y格式），进行波动方程正演，该程序是最简单的声波正演，而且运用了open+MP技术提升运算效率。
