本教材以操作系统原理为主线，结合当今主流操作系统设计方法。(The principles of materials to the main line operating system, combined with today' s mainstream operating system design.)

操作系统学习中的模拟CUP如何调度外部进程的算法—优先度调用算法(Analog CUP in the operating system, learn how to schedule external process algorithm- priority call algorithm)

1．虚拟存储器的引入 局部性原理：程序在执行时在一较短时间内仅限于某个部分；相应的，它所访问的存储空间也局限于某个区域，它主要表现在以下两个方面：时间局限性和空间局限性。 2．虚拟存储器的定义 虚拟存储器是只具有请求调入功能和置换功能，能从逻辑上对内存容量进行扩充的一种存储器系统 (1. The introduction of virtual memory locality principle: program execution in a relatively short period of time limited to a particular part of it Accordingly, it has access to the storage space is also limited to a particular region, it is mainly manifested in the following two aspects: the time limitations and space limitations. 2. The definition of virtual memory Virtual memory is just a request for redeployment of functions and displacement functions, from the logical to expand the memory capacity of a memory system)

驱动调度+操作系统+模拟电梯调动的算法程序，使用C++编写。(Driven scheduling algorithm procedures, the+ operating system+ simulated lift mobilize written using the C++.)

说明：  Unix 成组链接法 模拟UNIX系统的空闲块成组链接法，实现磁盘存储空间的管理(Unix Group Links UNIX System Simulation of spare pieces Group link, disk storage space to achieve the management)

说明：  这是一个操作系统中关于调度问题中的先来先服务调度算法。(This is an operating system on the scheduling of a first-come first-served scheduling.)

说明：  用标准C实现shell功能,是操作系统的作业，Linux里面的she(Shell to achieve using standard C function, the operation is the operating system, Linux inside she)

这是我做的操作系统里面的银行家算法的源程序，发上来供大家参考。(caozuoxitongyinhangjiasuanfa)

从程序员的角度看计算机操作系统~ 很不错的书 大家都加油了(Computer Systems--A Programmer s Perspective)

制冷专业软件，非常实用，可计算制冷系统，制冷剂的物性(Refrigeration professional software is very useful, computable refrigeration system, refrigerant properties)
