最近 LCC 谐振变换器备受关注，因为它优于常规串联谐振变换器和并联谐振变换器：在负载和输入变化较大时，频率变化仍很小，且全负载范围内切换可实现零电压转换（ZVS）。本文介绍了LLC型谐振变换器的分析方法，回顾了LLC型谐振变换器的实际设计要素。其中包括设计变压器和选择元器件。采用一设计实例，逐步说明设计流程，有助于工程师更加轻松地设计LLC谐振器。(Recently LCC resonant converter has attracted much attention, because it is better than that of the conventional series resonant converter and parallel resonant converter in the load and input change, frequency change is still very small, and the whole range of the load switch can realize zero voltage switching (ZVS). In this paper, the analysis method of LLC resonant converter is introduced, and the practical design elements of LLC resonant converter are reviewed. Including the design of transformers and components. A design example is used to explain the design process step by step, which is helpful for engineers to design LLC resonators more easily.)

This book provide readers with the use of MATLAB practical guidance. Mainly with the introduction of the MATLAB control engineering related to six basic toolbox: System Identification Toolbox, Control System Toolbox, Robust Control Toolbox, Model Predictive Control Toolbox.)

Mark Filipiak的网格生成，是网格生成的经典著作。包含结构与非结构网格，以及自适应网格。(Mesh generation of Mark Filipiak, is a classic work of grid generation. Including structured and unstructured meshes, and adaptive mesh.)

Qt，和 wxWidget 一样，它也是一个标准的 C++库。但是它的语法很类似于 Java 的 Swing，十分清晰，而 且 SIGNAL/SLOT 机制使得程序看起来很明白——这也是我首先选 择 Qt 的一个很重要的方面，因为我是学 Java 出身的 :) 。不过，所谓“成也萧何，败也萧 何”，这种机制虽然很清楚，但是它所带来的后果是你需要使用 Qt 的 qmake 对程序进行预 处理，才能够再使用 make 或者 nmake 进行编译。并且它的界面也不是原生风格的，尽管 Qt 使用 style 机制十分巧妙的模拟了本地界面。另外值得一提的是，Qt 不仅仅运行在桌面环境 中，Qt 已经被 Nokia 收购，它现在已经会成为 Symbian 系列的主要界面技术——Qt 是能够 运行于嵌入式平台的。(Qt, and wxWidget, it is also a standard C++ library. But its syntax is very similar to Java' s Swing, very clear, and SIGNAL/SLOT mechanism makes the program seem to understand- and this is my first choice is a very important aspect of Qt, because I was born to learn Java :). However, the so-called " as also Xiao, also lost" , although this mechanism is clear, but its consequences is that you need to use Qt' s qmake program is preprocessed, it can be reused make or nmake to compile. And its interface is not the native style, despite the use of Qt style very clever mechanism to simulate the local interface. Also worth mentioning is that, Qt only run in the desktop environment, Qt has been acquired by Nokia, it has now become the main interface technology Qt Symbian series is the ability to run on embedded platforms.)

一个HTML文件是一页文字信息，就象一封电子邮件或一个word字处理文档，而且实际上你完全可以使用Word字处理软件来编写一个HTML网页。你也可以通过其它字处理软件编写文本文件，网络浏览器只能处理文本信息。 (An HTML file is a text message, an email or a word as word processing documents, and in fact you to write a complete HTML page can use Word word processing software. You can also write a text file by other word processing software, web browsers can handle only text messages.)
