Undocumented items in the DDK in Windows NT 书中涉及处皆是系统核心奥妙之所在，常人皆对此望而却步。内存操作、各类钩挂、系统服务、软件中断等等系统黑客必掌握之绝技，此书皆有论述，且其内容之深入、之实际以往经典中也难得一见。然内容虽深数却不难懂，作者论述深入浅出，稍有难点便细致讲解，更有数处令吾甚感罗嗦，其讲解之到位，可见一斑。更可贵之处在于，此书不仅受人以鱼，更受人以渔。特辟一章专讲反向工程之技巧，其意在鼓励人从此可自立门户，自行探索系统之奥秘。师父领进门，修行在个人，此言不差。有宝典在手，日日勤读善思，不愁大功不成(no need)

书籍《21天学通C#》用超星阅读器打开的，其它的我就不多说了(Books " 21 Days pass C#" with the Super Star reader open, the other I will not say more)

!本程序主要用来解决二维平面应力弹性问题（带厚度），在f90上调试通过。 !包含主程序STRESS和三个字程序ELSTMX(KK)、MODIFY、DCMPBD和SLVBD !主程序主要进行基本的输入输出以及最大半带宽的计算，组装总体刚度矩阵计算的应力应变值 !子程序elstmx(kk)计算刚度系数矩阵，生成第kk单元的刚度矩阵k !子程序MODIFY输入节点的集中力，边界节点的位移，对总体刚度矩阵和位移数组和节点力数组作修改 !子程序DEMPBD用高斯消元法将半带宽的矩阵变成上三角阵 !子程序SLVBD为总体矩阵的回代求位移向量DD(!
