通过图形化的界面模拟操作系统中动态分区存储管理方式的内存分配与回收，采用的算法有首次适应算法和最佳适应算法，并且能实现内存回收功能，包括单独回收；与上边空闲区邻接，合并回收；与下边空闲区邻接，合并回收；与上、下边空闲区邻接，合并回收。-Through the graphical interface of the dynamic simulation of the operating system partition storage management and recovery of the memory allocation, the algorithm used to adapt the first and best adaptation algorithm algorithms, and to achieve the recovery of memory function, including a separate recovery　and top free zone adjacent to, the combined recovery　and below the adjacent free zone, the combined recovery　and on the free zone adjacent to the bottom, the combined recovery.
