主要介绍了等精度频率测量原理，该原理具有在整个测试频段内保持高精度频率
测量的优点 同时在该原理基础上，采用了Verilog HDL语言设计了高速的等精度测频
模块，并且利用EDA开发平台QUARTUS11 3 .0对CPLD芯片进行写人，实现了计数等
主要逻辑功能 还使用C语言设计了该等精度频率计的主控程序以提高测量精度。本设
计实现了对频率变化范围较大的信号进行频率测量，能够满足高速度、高精度的测频要
求。-Introduced, such as the accuracy of frequency measurement principle, the principle has in the entire test frequency to maintain the advantages of high precision frequency measurement at the same time the basis of the principle of using the Verilog HDL language, such as the design of a high-speed precision frequency measurement module, and use of EDA Development platform QUARTUS11 3 .0 on CPLD chip to write, and achieved a count of the main logic function, such as the use of C language is also designed such precision the frequency of control procedures to enhance measurement accuracy. This design achieved a wide range of frequency changes in signal frequency measurement, to meet the high-speed, high precision frequency measurement requirements.

建设一个网站,会遇到多人连接服务器的问题.如果用tomcat作为JAVA服务器,可以写一个连接池程序.但最新的5.0.16tomcat已经支持连接池配置,我个文档就是讲如何设置的,花了一天功夫!-building a website, will face many problems connecting to servers. If tomcat as a Java server, can write a connection pool procedures. But the latest 5.0.16tomcat have supported the connection pool configuration files, I was speaking of how to set up and spent all day effort!
