JSTL是一个不断完善的开放源代码的JSP标签库，是由apache的jakarta小组来维护的。JSTL只能运行在支持JSP1.2和Servlet2.3规范的容器上，如tomcat 4.x。但是在即将推出的JSP 2.0中是作为标准支持的。(JSTL is a continuous improvement of the open-source JSP tag library, are from the jakarta group apache to maintain. JSTL can only run in support of JSP1.2 and norms Servlet2.3 containers, such as tomcat 4.x. However, in the upcoming JSP 2.0 is supported as a standard.)

基于C/S环境下的自动升级技术文档，教你如何实现程序设计-Based on C/S environment automatically upgrade technical documentation, teach you how to program design

本代码，直接编译可用，解决NP难问题使用的是局部最优BFD算法，其中用到了链表以及大顶堆排序算法(This code can be compiled directly, and it can solve the NP hard problem. It uses the local optimal BFD algorithm, which uses the linked list and the big stack sort algorithm.)

迭代法阈值分割图像，可以实现精确地像素级分割。(Iterative threshold segmentation of images)

LL(1)文法和预测分析方法 1.文法使用产生式来定义； 2.分别求出文法中每一个非终结符的FIRST集、FOLLOW集和SELECT集； 3.画出预测分析表； 4.判定给定的文法是否是LL(1)文法； 5.给定符号串判定是否是文法中的句子，分析过程用分析表格的方式打印出来。(LL(1) Grammar and Predictive Analysis 1. Grammar is defined by production. 2. Find out the FIRST set, FOLLOW set and SELECT set of each non-terminator in grammar. 3. Draw a forecast analysis table. 4. Determine whether a given grammar is LL(1) grammar; 5. Given a string of symbols to determine whether it is a sentence in grammar, the analysis process is printed out in the form of an analysis table.)

Compared to the development of computers, or the Internet, or even cars, the evolution of aviation equipment appears to be very unhurried. Several factors contribute to this very gradual pace, but one of the most important is the extreme care with which any innovation affecting safety has to be examined, evaluated, analyzed, and tested. Satellite navigation equipment for aircraft is not an exception, so predicting its future for the next20 years is relatively easy compared to predictions for other fields. In this paper first of all we will describe briefly the challenges that satellite navigation must solve to be available solution for aviation. Then, we will describe the systems that have been developed to overcome these challenges and the performance they offer today, or will offer very soon. There is currently an explosion in satellite Navigation: before the end of this decade there will be over three times more satellites, offering civil signals in two distinct frequencies (as opposed to one today).
