说明：  给出一些离散的点，根据最小二乘法求出拟合的直线。(If there are some discrete points, you can get a line based on least square method.)

通过分析比较3种聚焦效果较好的清晰度评价函数，提出了一种基于聚焦窗口模式的平方梯度函数作为聚焦评价函数，建立了评价函数的数学模型，并给出了实验分析和结果。与以往常用的评价函数相比，具有更高的可靠性和聚焦灵敏度(Compared by analyzing the three kinds of focus better clarity evaluation function, a model based on the focus window as a function of the square gradient focusing evaluation function, the establishment of the evaluation function of the mathematical model, and gives the experimental analysis and results. Commonly used in previous evaluation function, compared with higher reliability and sensitivity Highlights)

在C8051F060中添加了头文件以更好的应用(DESCRIPTION: Register/bit definitions for the C8051F060 product famil)

简单实现临街资源互斥的使用，用四个全局变量实现互斥。(Simple resources to achieve mutually exclusive use of the street, with four global variables to achieve mutually exclusive.)

数据库开发的ado连接，包括存入图像，读取图像的方法，值得入门的学习下(Ado connection database development, including into the image, read the image, it is worth to study the entry)

这是WinIo.dll的一个使用实例，用VC++实现计算机并行端口数字信息的输入与输出，演示程序包括了常用的获取信息、发送信息的程序示例。(This is a WinIo.dll use of examples, using VC++ to achieve digital information the computer parallel port input and output, including presentation of the commonly used procedures to obtain information, send a message of the program sample.)

vc——使用MediePlay AcriveX控件创建媒体播放器MyMediaPlay(vc- Use MediePlay AcriveX controls to create media player MyMediaPlay)

vc 代码控制链接ODBC的程序源码，希望对大家有所帮助(vc code control procedures linked ODBC source, we hope to help)

从libnids得到TCP重组的数据，当libnids的状态为NIDS_JUST_EST时，表示TCP建立连接，在此时给TCP流增加一个flow_id用来标识此连接；当libnids的状态为NIDS_DATA时，表示接受数据，当有新的数据到达时，根据flow_id把数据push到相应的流表中，为之后的数据分析做准备。因此，可以在此框架上增加符合http协议的应用解析(Data TCP libnids restructuring, when libnids status to NIDS_JUST_EST, said the TCP connection is established, at the same time adds a flow_id to TCP flow is used to identify this connection When libnids status to NIDS_DATA, accepted data, when new data arrives, according to flow_id to push data to the corresponding flow table, prepare the way for after data analysis. Can be increased on this framework, therefore, in accordance with the application of the HTTP protocol parsing)

列举制定的目录中被打开的文件，和打开这些文件的进程的PID，命令：lof 驱动文件 目标文件夹。由于驱动的限制，该程序仅适用Windows 2000/XP。(Listed in the directory has been developed to open the file, and open the files of the process PID, the command: lof driver file destination folder. As the driving restrictions, the program applies only to Windows 2000/XP.)
