msp数据采集系统实现。通过传感器进行有效的采集。-msp data acquisition system. Through the effective acquisition sensors.

本程序利用五阶WENO格式结合Lax-Friedrichs矢通量分裂法求解二维Euler 方程(u_t = RHS = -f(u)_x - g(u)_y)的空间项，应用三阶TVD Runge-Kutta法 求解其时间项来模拟Riemann间断问题.(The program uses five order WENO scheme combined with Lax-Friedrichs vector flux splitting method to solve two-dimensional Euler. Equation (u_t = RHS = -f (U) _x g (U) _y) space terms, the three order TVD Runge-Kutta method is applied. The time term is solved to simulate the Riemann discontinuity problem.)

说明：  This is LS PLC software and is used for programming

独数问题计算，可以自动计算和判断给定的独数矩阵，然后分析计算-Independent calculation of the number of problems, you can automatically calculate and judge the independence number of a given matrix, and then analysis

说明：  搭建虚拟网络仿真环境，可直接运行，可用于了解虚拟网络的映射过程(Build virtual network simulation environment, can run directly, can be used to understand the mapping process of virtual network)

一个虚拟主机代理系统-a virtual host Agent System

在VB环境下生成柱状图的例子，VB6.0调用MSChart控件生成柱状图图表一例，程序要用到Access数据库，从中读取数据库后，对数据进行分组统计，然后使用MSChart所提供的方法，生成柱状图表，直观的表现出数据的差异性。

factory design pattern implementation

说明： 1、先在“产生式”框中输入产生式，在“输入的符号串”框中输入待分析的符号串，点击“编译”按钮开始根据产生式分析输入的符号串。 2、在“范例”菜单中可以选择预选的产生式和输入符号串范例，有两个范例，其中书上范例为“范例代码2”。 3、“产生式”框中，“显示消除左递归结果”选中时，执行编译后如果“产生式”框内内容没有变化，则原输入的产生式符合LL(1)，否则，“产生式”框内内容将转换为符合LL(1)的文法。-: 1, the first "production" box importation of production, "input string of symbols" input box to the symbol series analysis, Click on the "Build" button to begin production analysis of the input string of symbols. 2, the "paradigm" menu can choose a pre-production series and the importation of symbols example, there are two examples, which book example of "two examples of code." 3, "have a" box, "showed that the elimination of left recursive results" selected, If, after the implementation of compiler "production" box contents have not changed, then the importation of the production line with LL (1), otherwise, "Production" box contents will be converted to meet LL (1) grammar.
