DUNE (Distributed and Unified Numerics Environment)，分布和统一数值解环境，是一种求解偏微分方程的基于网格的方法（PDE）的模块化的工具箱。DUNE是所有这些体现了科学计算的概念从抽象的接口设置第一次。现代C + +编程技术使同样的概念非常不同的实现使用一个非常低的开销一个共同的接口。因此，DUNE确保在科学计算的效率，并支持高性能计算应用。(DUNE (Distributed and Unified Numerics Environment), distribution and unified numerical solution of the environment, is a solution of partial differential equations of the grid-based methods (PDE) of the modular toolbox. DUNE is that all these reflect the concept of scientific computing from the abstract interface settings for the first time. Modern C++ programming techniques to the same concept is very different implementations use a very low cost of a common interface. Therefore, DUNE ensure the efficiency of scientific computing, and supports high-performance computing applications.)

平面波是一种理想的电磁波，许多复杂的电磁波能分解成均匀平面波的叠加形式，研究平面波的传输问题有很强的现实意义，本文利用场匹配法和等效传输线法对平面波入射分成介质问题进行分析，计算出总的反射系数，并利用Matlab软件对频率在0-10GHz的平面波进行了仿真对比，加深了对平面波传输的理解。(Plane wave is an ideal electromagnetic waves, many of the complex electromagnetic waves can break down into a uniform plane wave superposition form, strong practical significance in the study of plane wave transmission problem, this article use field matching method and the equivalent transmission line method for plane wave incident divided into problems with media conduct analysis, calculate the total reflection coefficient, and the use of Matlab software plane wave in the 10GHz frequency simulation compared to deepen the understanding of plane wave transmission.)

说明：  智能控制仿真GUI界面，对离散化的受控对象进行不同方式的控制（包括传统PID控制、模糊PID控制、神经PID控制和专家及仿人智能控制），然后通过分析不同条件下的单位阶跃响应指标，比较各控制方式之间的差异及控制特点。(intelligent control GUI)
