摘　　要：进程是让操作系统实现程序的并发执行、系统资源共享、用户随机使用系统等功能的重要概念。文章首先介绍进程在Ｌｉｎｕｘ内核中的表示方式，然后结合源代码深入分析进程的时间片轮转、先进先出、Ｒｏｕｎｄ ｒｏｂｉｎ调度策略的具体实现，对我们进一步了解 Ｌｉｎｕｘ内核的工作机制和学习编程均有较好的实用参考价值。Process is a very important conception for operation system because it makes the OS realize excuting program non - sequentially, sharing the system resources and using system at random. Process's data structure in linux kernal is introduced in this paper. And then the time slice cycle, first in first out and round robin scheduling methods are deeply analyzed combined with linux kernel code. These have good practical referring value for us to understand linux kernel's working mechanism and learn programming.
