摘　　要：基于对Linux操作系统内存管理机制、算法和模式的分析,详细解读Linux内核2.6版本中有关内存池的定义内涵,明确内存池的创建方法和调用原理,并给出内存池在网络文件系统中的应用。实验表明,在内存实现及用户程序中使用内存池进行内存管理,可以减少内存碎片,提高分配速度,防止内存泄露。After that the memory management pattern of Linux is analyzed,the definition of the memory pool in the kernel（version 2.6） of Linux is unscrambled,and the methods to create or transfer the memory pool are nailed down,besides,an example is given to show how the memory pool works in network file system.Experiments show that,when the memory pool is introduced for memory management into memory implementation and user program,the number of memory pieces will be reduced,the speed of distribution will be improved,and the leaks of memory will be avoided.
