本程序主要作用与TXT电子小说的阅读，在您的阅读过程中程序可自动翻页，并且您还可以自己设置自动翻页时间间隔，程序自带书签功能，您可以随时保存您的阅读进度方便下次的阅读，程序会在您打开的TXT文件的相同目录下创建一个*.m的文件，此文件为书签文件，删除后会造成保存的阅读进度的丢失。 开发平台 vs 2008 -A major role in this process with TXT e-fiction reading, in the course of your reading program can be automatically flip, and you can also set up their own auto-flip time interval, the program comes with a bookmark feature, you can always save your progress to facilitate reading the next reading, the program will open in your TXT file the same directory to create a*. m files, the file for the bookmarks file, delete saved will result in the loss of reading progress. Development platform vs 2008

这是以前自己写的一个进度条，有几种样式。现在开源共享，以求共进，如果大家用过有什么建议可以提出来。-This is a Writing before the progress of their article, there are several styles. Now open-source sharing, in order to attend, if there is what everyone used to put forward proposals.

This bar is similar to the Outlook, Outlook express, or Front Page 98 editor. It is useful to display application specific information with text and bitmaps. You can change dynamically 信息栏和Outlook，Outlook express或Front Page 98编辑器上的相似。用它来通过本文和位图显示应用程序的特性信息非常实用。你能动态地改变它-This bar is similar to the Outlook, Outlook express, or Front Page 98 editor. It is useful to display application specific information with text and bitmaps. You can change dynamically information fence and Outlook, Outlook express or Front Page 98 editors on similar. Comes with it through this article and the position chart demonstrated the application procedure the characteristic information is extremely practical. You can dynamic change it

人们在使用SQL时往往会陷入一个误区，即太关注于所得的结果是否正确，而忽略了不同的实现方法之间可能存在的 性能差异，这种性能差异在大型的或是复杂的数据库环境中（如联机事务处理OLTP或决策支持系统DSS）中表现得尤为明 显。笔者在工作实践中发现，不良的SQL往往来自于不恰当的索引设计、不充份的连接条件和不可优化的where子句。在对 它们进行适当的优化后，其运行速度有了明显地提高！下面我将从这三个方面分别进行总结：-people in the use of SQL often fall into the trap, that is too focused on the findings is correct, and ignore a different method may exist between the performance differences, these differences in large or complex database environment (such as online transaction processing or decision support OLTP system DSS) has become even more obvious. In practice I found that the poor tend to SQL from inappropriate design of the index, not fully connected and non-optimal conditions where the phrase. On their proper optimization, and their operating speed has been improved! Now I will be three aspects of this summary :

This is a GUI based system. The GUI is invoked from the command line by typing "ui_start". The GUI is self explanatory. Tool tips are given in blue color. The cursor needs to be positioned on these for detailed explanation. The main file is  "runsim.m". In these simulations the SISO option is not explicitly given. This is because the SISO result for a particular type of modulation is shown in every plot for purposes of comparison.
