项目采用eclipse3.3+myeclipse6.0.1GA+SQLServer2000+TomCat6.0开发，实现了简单的论坛功能。 设置分页条数分别在forumdisplay.jsp（10行）和viewthread.jsp（17行） 数据库采用直连，驱动在项目文件夹下，jtds-1.2.2.jar -Project uses eclipse3.3+ myeclipse6.0.1GA+ SQLServer2000+ TomCat6.0 develop, implement a simple forum function. Set the number of pages, respectively forumdisplay.jsp (10 lines), and viewthread.jsp (17 lines) database using Direct Connect, the driver in the project folder, jtds-1.2.2.jar

加强肋 理想的设计 为了克服壁厚大可能引起的问题，使用是一种可减少壁厚并能增加刚性的有效方法。 一般来说，部件的刚性可用以下方法增强 增加壁厚； 增大弹性模量（如加大增强纤维的含量）； 设计中考虑。 如果设计用的材料不能满足所需刚性，则应选择具有更大弹性模量的材料。简单的方法是增加塑料中增强纤维的含量。但是，在特定壁厚下，这种方法仅能使刚性呈线性增长。更有效的方法是使用经过优化设计的。由于惯性力矩增大，部件的刚性便会增大。在优化的尺寸时，不但要考虑工程设计应当考虑的问题，还应考虑与生产和外观有关的技术问题。 优化的尺寸 大的惯性力矩可很容易地通过设置又厚又高的来实现。但是对热塑性工程塑料，这种方法常会产生制品表面凹痕、内部空洞和翘曲等问题。而且，如果的高度过高，在负荷下结构将有可能膨胀。出于这种考虑，必须在合理比例内保持的尺寸（见图1）。-stiffened ideal for the design of large thickness overcome the problems that may arise. use of a reduced wall thickness and rigidity can increase the effective method. In general, the rigid parts of the following methods can be used to enhance increased thickness; increased elastic modulus (such as increasing fiber content); Design considerations. If the design of the materials used can not meet the rigid requirements, they should have a greater choice of elastic modulus of the material. The simple way out is to increase plastics reinforced fiber content. However, in s

80C51的串行通信口是一个功能强大的通信口，而且是相当好用的通信口，用于显示驱动电路再合适不过了，下面我们就根据这种需要设计一个用两个串行通信口线加上两根普通I/O口，设计一个4位LED显示电路。当然只要再加上两根I/O口线即可轻易实现8位LED的显示电路。 -80C51 Serial Communications mouth is a powerful communications mouth, but is very handy communications mouth, for the display driver circuit could not have been more appropriate, Now we need to design the basis of this one with two serial communication lines with two general I/O Hau, Design of a four LED display circuit. Of course if coupled with two I/O lines I could easily achieved eight LED display circuit.

Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.
