grids的翻译

4) This thesis presents two PC-based streamline visualization methods for large unstructured grids: Memory-Mapped File Method ( MMFM) and MultiThread Out-of-core Method ( MTOM).

4）针对大规模非结构网格，提出了两种基于PC的流线可视化方法：内存映像文件方法（MMFM）和多线程out-of-core方法（MTOM）。

These physical processes can be turned into the problems of solving large-scale partial differential equations. If we use uniform grids, the space-step and the time-step must be small enough to resolve these problems within a given accuracy.

如果使用均匀的网格系统，要得到关于这类问题的较精确的解，需要使用足够小的空间步长和时间步长，这就大大增加了计算成本，从而限制了所解决的问题的规模。

Getting the potential distribution of grounding grids accurately in time-varying field, the analysis of electromagnetic interference may be analyzed.

时变激励下的接地网模拟计算能够较为准确地求得接地网上的电压分布，从而进行变电站内电子设备之间的电磁干扰分析。
