multisim软件是画图仿真领域的龙头，而这个文件是个好的开始(the multisim Software is drawing the the simulation field' s leading, and this document is a good start)

本源代码用三种不同的方法对三个数求最小公倍数，分别是循环穷举法，短除法和函数嵌套法。( Common multiple of three numbers Circular exhaustion Short division Function nesting)

说明：  pb调用delphi dll拼、解析json(transfer temporarily for a specific task; call; invoking)

说明：  LS-DYNA-USERDEFINED-MATERIAL-with-failure

定义了不同cad图元属性，方便生成cad实体类(Constructs cad Entity with minimal arguments.)

说明：  面向C/C++ 代码的漏洞检测系统原理与实现 实用 有意义(For C/C++ code vulnerability detection system theory and practical implementation meaningful)

线调频小波路径算法的计算程序，实现信号瞬时频率追踪(The calculation program of the linear frequency modulation wavelet path algorithm to realize the tracking of the instantaneous frequency of the signal)

（1）定义一个抽象基类Shape,同它派生出5个类：圆、正方形、矩形、梯形、三角形。 （2）利用虚函数计算几种图形面积。 （3）演示构造函数、复制构造函数、析构函数的作用和调用顺序 （4）用类模板具体实现。 （5）利用MFC类库在图形用户界面上绘制及修改这些图形，采用对话框输入输出图形的基本属性，或者利用运算符重载输入输出图形的基本属性。 （6）用文件保存图形信息，且能够从文件中读取并作相应处理。 2）创新要求： 采用头文件与源文件分离的方法，多态性的实现多样化(defines an abstract base class Shape, with which it derives five categories: round, square, rectangular, trapezoidal, triangular. (2) the use of virtual functions to calculate several graphics area. Effect (3) demonstrate the constructor, copy constructor and destructor call sequence (4) with a class template implementation. (5) The use of MFC library to draw and modify graphics, using the basic properties dialog input and output graphics, or the use of the basic properties of operator overloading the input and output graphics on the graphical user interface. (6) with the file save graphical information, and can be read a file and make the appropriate treatment. 2) Innovation requirements: Using the method header and source files separate polymorphism diversify )

说明：  实现了中等难度的图书管理系统，可以进行图书统计，检索，借阅，归还等等(It realizes a medium-difficulty library management system, which can carry out book statistics, retrieval, borrowing, returning and so on.)

C#的日志工具，思路log4j跟一致.请参阅本站关于log4j的其他资源(C# log tools, consistent with the idea of log4j. Please refer to this site on other resources log4j)
