哲学家进餐问题是荷兰学者Dijkstra 提出的经典问题之一,它是一个信号量机制问题的应用,在操作系统文化史上具有非常重要的地位。对该问题的剖析有助于学生深刻地理解计算机系统中的资源共享、进程同步、死锁等问题,并能熟练地应用信号量来解决生活中的控制流程,即将生活中的控制流程用形式化的方式表达出来。 假设有5个哲学家，他们花费一生中的时光思考和吃饭。这些哲学家共用一个圆桌，每个哲学家都有一把椅子。在桌子中央是一碗通心面，在桌子上放着5只筷子。（如图所示）当一个哲学家思考时，他与其他同事不交互。时而，哲学家会感到饥饿，并试图拿起与他相近的两只筷子（他与邻近左、右之间的筷子）。一个哲学家一次只能拿起一只筷子。显然，他不能从其他哲学家手里拿走筷子。当一个饥饿的哲学家同时有两只筷子时，他就不能不用释放他的筷子而自己吃了。当吃完后，他会放下两只筷子，并再次开始思考。 规定奇数号哲学家先拿他左边的筷子，然后再去拿右边的筷子；而偶数号哲学家则相反。按此规定，将是1、 2号哲学家竞争1号筷子；3、4号哲学家竞争3号筷子。即五位哲学家都先竞争奇数号筷子，获得后，再去竞争偶数号筷子，最后总会有一位哲学家能获得两只筷子而进餐。 -dining philosophers problem is the Netherlands scholars Dijkstra"s one of the classic, It is a signal to the mechanism of application, the operating system in the history of culture has a very important position. Analysis of the problem to help students understand deeply the computer system resource sharing, process synchronization, and other issues Deadlock, skilled and can be applied to solve the signal volume life of the control flow, about the life of the control flow wi

该PPT先介绍了c语言的基础，然后有介绍了MFC，是初学者的参考教材-PPT introduced the first basis of c language, and then have introduced the MFC, is a reference material for beginners

这里介绍的是如何用80C51单片机来实现长春工业大学的毕业设计，该设计是结合科研项目而确定的设计类课题-This article introduces the CCUT graduation design with the 80C51 single chip computer.

ti公司关于h263解码的详细文档，很难找。做DSP视频开发的可以参考。-ti company on the H263 decoding detailed documentation, it is difficult to find. Does the development of DSP can refer to video.

如果在keil开发中遇到问题，可以到该文档去查询，可以解决keil开发中大量的问题。-if keil development encounter problems, they can go to the document to make inquiries, can be solved keil development of a large number of issues.

关于指纹识别系统的c++源代码。以FPGA作为核心控制器件，实现指纹图像的采集、存储、处理和比对等，完成对指纹图像的有效识别。        

Microsoft Visio 是微软公司生产的一个强大的图形设计软件，专门用于绘制比如数据库设计图、流程示意图、系统结构图的图形设计软件。如同其OFFICE系列软件一样，有着强大而繁多的功能，在程序和工程设计中被广泛的应用。-Microsoft Visio, Microsoft produced a powerful graphic design software, such as devoted to mapping database design, process diagram, the system structure of the graphics design software. Like its OFFICE Series software, which has a strong range of functions, procedures and engineering design was widely used.

显而易见，我的一个小实验程序。有用的确良好/-It is obvious that I, a small experimental procedures. Useful indeed good /

它是一个完整的程序。 它写在 PureBasic 中，并使用食人魔引擎。 其本质-在优美的环境中显示照片。

If the resistor that charges the capacitor is too low in value (or if the power supply voltage is too high), the current through the transistor will not become low enough for the transistor to turn off. If the resistor that charges the capacitor is too high in value (or the power supply voltage is too low), the  capacitor will not be able to charge to a high enough voltage to enable the transistor to turn on.  This is because the transistor draws as small amount of current before switching on.
