一个用于天线伺服转台的程序，根据飞机飞行的GPS实时数据，解算出地面伺服天线转台的俯仰角和方位角，指导天线输出，对准飞机位置(A program for the antenna servo turntable, according to the aircraft flying GPS real-time data, the ground servo antenna turntable tilt angle and azimuth, to guide the antenna output, alignment aircraft position)

用纯C语言编写的一个Linux下的Shell，包含tch和bash的基本功能（包含重定向和后台运行），暂时不支持管道。已经在cygwin和Ubantu 7.10下测试通过。 主要包含： makefile 编译生成myshell可执行文件 myshell.c 主函数（涉及程序入口） utility.c 所有功能函数（将近1000行） myshell.h（包含宏定义、结构体声明、库函数的头文件，及utility.c中的所有函数的声明） readme 用户手册（当用户在myshell里输入help <command> 时，输出<command>的使用说明） (With pure C language under Linux in a Shell, contains tch and bash the basic functions (including redirect and running in the background), the moment does not support the pipeline. Has been under cygwin and test Ubantu 7.10. Mainly includes: makefile compiler generated executable file myshell main function myshell.c (relating to procedures for entrance) utility.c all the features of function (nearly 1000 lines) myshell.h (contains macro definition, the structure declaration, the first document library, and all utility.c statement function) readme user' s manual (when users enter help in myshell <command> , The output <command> The use of explanation))

磁盘文件系统：建立基于磁盘存储设备的UNIX文件系统，在windows系统下模拟UNIX文件管理系统，可用命令行进行基本的文件操作。(Disk file system: the UNIX file system based disk storage devices in the windows system simulation UNIX file management system, basic file operations available command line.)

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)

银行家算法是一种最有代表性的避免死锁的算法。又被称为“资源分配拒绝”法(Bankers algorithm is one of the most representative of the algorithm to avoid deadlock. Also known as "resource allocation denial" method)
