1、 采用原始变量法,即以速度U、V及压力P作为直接求解的变量 2、 守恒型的差分格式,离散方程系对守恒型的控制方程通过对控制容积作积分而得出的,无论网格疏密程度如何,均满足在计算区域内守恒的条件; 3、 采用区域离散化方法B,即先定控制体界面、再定节点位置 4、 采用交叉网格,速度U、V与其他变量分别存储于三套网格系统中; 5、 不同的项在空间离散化过程中去不同的型线假设,源项采用局部线性化方法;扩散——对流项采用乘方格式(但很容易转化为中心差分、迎风差分或混合格式);街面上的扩散系数采用调和平均法,而密度与流速则用线性插值; 6、 不稳态问题采用全隐格式,以保证在任何时间步长下均可获得具有物理意义的解; 7、 边界条件采用附加源项法处理; 8、 耦合的流速与压力采用SIMPLE算法来求解; 9、 迭代式的求解方法,对非线性问题,整个求解过程具有迭代性质;对于代数方程也采用迭代法求解; 10、 采用交替方向先迭代法求解代数方程并补以块修正技术以促进收敛。

I want to provide an example file system driver for Windows NT/2000/XP. For some time I have worked on an implementation of RomFs. RomFs is a small filesystem originally implemented in Linux, because of its simple disk layout its a good choice for an example driver. The current status is a working read-only driver that supports caching of file data, the create functionallity still needs some work but I m releasing it due to the high public demand.

这是用VC6.0开发的集词法分析、语法分析、语义分析为一体的一个程序,是我在编译原理课程设计后期和同班一贼牛的哥们儿老胡共同研究的,做编译课设的朋友们不妨下来看看。语法分析采用的是算符优先分析法,语义生成的是四元式,符号集等格式处理方面基本是遵照大连理工出版的《编译原理》一书附的Simple语言来设计的。由于是自己的课余研究,当时没什么文档和维护的概念,因此没有留下文档,事隔一年半之后我也没有再研究它的动力了,看懂了的朋友不妨写个文档传上来告诉我一声!先此谢过了!
