The only difference between the '-D' and the '-P' options is, that the latter predefines a macro such, that it is not undefinable through an #undef directive from inside the preprocessed program.

D' 选项和'-P'选项的区别在于，后者是预定义一个宏，即这个宏不能从预处理的程序内部通过#undef 指令来去定义。

Chapter 8: We discuss the acceleration of multigrid by Krylov subspace approaches, and recognize the reason for slow convergence of algebraic multigrid methods is that error reduction is significantly less efficient for some very specific error components which may cause a few eigenvalues of the algebraic multigrid iteration matrix to be considerably closer to 1 than all the rest. However, the eigenvectors belonging to the few isolated eigenvalues can be expected to be typically captured after only a few conjugate gradient iterations, which accelerate algebraic multigrid algorithms. Theoretical analysis and numerical results of some practical problems show the iterant recombination accelerates algebraic multigrid convergence.

第八章：先介绍用Krylov子空间迭代法加速一般多重网格方法收敛的基本框架，然后紧紧抓住引起代数多重网格方法收敛减慢的根本原因往往是误差减小对几个特别的误差分量不明显，这导致代数多重网格方法的迭代矩阵的几个特征值接近于1，而共轭梯度方法则能比较典型地捕捉属于孤立特征值的特征向量，从而推导出有效的共轭梯度加速算法和程序实现，不仅从一些具体的实际应用例子的数值结果去验证迭代复合加速收敛的效果，而且还从理论上分析了预处理共轭梯度法加速代数多重网格法收敛的机理。

The Wave library contains two different, interchangable C++ lexers, which may be used as a starting point during developing your own application. The lexer generated tokens are transformed by the preprocessing engine (macro expansion, include file processing etc.) and after this returned to the user of the Wave library.

Wave 库带有两个不同的、可互换的C++ lexer，可以作为起点来开发你自己的应用程序。lexer生成的单词将被预处理引擎转换(宏展开、头文件处理等等)，然后返回给 Wave 库的用户。
