将不

Domain Decomposition Method change the problem in the knaggy domain to the problem in several convex domains which do not wrap. The whole solution is gained by alternating boundary conditions between Dirichlet condition and Neumann condition on the common boundary.

区域分裂法是将不规则凹凸区域上的求解问题化为多个不重叠凸区域上的求解问题，在公共的边界上用Dirichlet条件、Neumann条件交替迭代得到全区域上的解。

We will not use the Unix "mv" command, because Perl's rename() function renames file well enough ( see perldoc-f rename for details on when rename() won't do a good job).

我们将不使用Unix“mv”命令，因为用Perl的rename（）函数来重命名文件已经相当不错了（请参阅perldoc-f rename以获取当使用rename（）出问题时的详细信息）。

P-M diffusion process is ill-posed, so it needs to be translated into a well-posed problem via regularization before solved.

P-M扩散过程是不适定的，因此需要通过正则化的方法将不适定问题转化为适定问题加以解决。
