[Other] 实验报告3 DL : 0: 进程是程序在一个数据集合上运行的过程，进程是并发进行的，也即系统中的多个进程轮流的占用处理器运行。我们把若干个进程都能进行访问和修改的那些变量称为公共变量。由于进程是并发执行的，所以，如果对进程访问公共变量不加限制，那么就会产生“与时间有关”的错误，即进程执行后，所得到的结果与访问公共变量的时间有关。为了防止这类错误，系统必须要用同步机构来控制进程对公共变量的访问。一般说，同步机构是由若干条语句——同步原语——所组成。本试验要求学生模拟PV操作同步机构的实现，模拟进程的并发执行，了解进程并发执行时同步机构的作用。 -process is a procedure in the data set to run the process, the process is conducted with the system that is the rotation process more than the occupier runs. We have a number of process can visit and revision of those variables as public variables. As the process is complicated by the implementation, so if the right to visit public process variables without restrictions, it will have a "Time" is wrong, the implementation process, the results obtained with the public to visit the variables of time. To prevent such mistakes, the system must be used to control synchronization process bodies for public variables visit. In general, synchronous bodies of a number of statements -- synchronization primitives -- composed. This experiment simulated PV require students to simultaneously ope

[Other] 稀疏矩阵的运算器 DL : 1: 稀疏矩阵的运算器 [基本要求] 以“带行逻辑链接信息”的三元组顺序表表示稀疏矩阵，实现两个矩阵相加、相减、相乘的运算。稀疏矩阵的输入形式采用三元组表示，而运算结果的矩阵则以通常的阵列形式列出。这是出自清华大学　严蔚敏　吴伟民　编著的数据结构题集（C语言版）的第136页的实习4 -sparse matrix operations for the [basic requirements] "OK logical link with information" of the order form ternary group said Sparse matrix, Matrix achieve two together, subtract, multiply arithmetic. Sparse Matrix input form using ternary group, which runs the Matrix while the usual array listed.

[Other] sharkattackgame DL : 0: 是一个Applet程序，要在浏览器中或用appletviewer执行。当Applet运行时，鲨鱼会在水平方向持续移动，单击相应的按钮会改变鲨鱼的运动方向。游戏的目标是当猎物经过时，如果鲨鱼也处在该位置并且完全没入水中，则猎物才被捕获。猎物被捕获时会发出相应的提示音，并且猎物消失。-is an Applet procedures, and in a browser or appletviewer implementation. When the applet runs, sharks in the horizontal direction will be sustained mobile, click on the corresponding button will change the direction of the shark. The goal of the game when the game is through, if the sharks at the position and did not fully submerged, was captured prey. Prey to be arrested will be issued when appropriate tone and prey disappear.
