内存

The Memory Manager controls the page tables that define the mapping of virtual addresses onto physical memory.

内存管理控制页表，它定义虚地址的映射到物理内存。

The result is a significant decrease in performance as requests for memory lead to the so-called "swapping" of memory.

由于内存请求导致所谓的内存交换，造成系统性能大幅度下降。

It prevents excessive memory swapping and makes sure that a certain amount of memory isalways available, which results in performance increase and lower response times, especially if youare running many applications at the same time and tend to switch between them quite often.

该软件可以预防过度的内存交换并且可以确保一定数量的内存维持在可使用状态。这就可以确保性能的提升和较低的响应时间，除非你正在同时运行许多应用软件并且有在这些程序之间频繁切换的趋势。

This happens because if free memory falls below a minimum value, the host operating system continually frees up memory by swapping to disk to maintain that amount of free memory.

这种情况是因为空余的内存降低到了一个最小的数值，这时主机要不断地使用磁盘交换数据来释放内存。

Sites which need to serve more than 256 simultaneous requests may need to increase MaxClients , while sites with limited memory may need to decrease MaxClients to keep the server from thrashing (swapping memory to disk and back). More information about tuning process creation is provided in the performance hints documentation.

站点在需要处理大于256个并发的时候，需要增加MaxClients指令，同时，站点在有限的内存下需要减少MaxClients的值以便保持服务器不崩溃（太多的MaxClients需要从磁盘中进行内存的交换）更多的关于如何调整子进程创建的信息请参照性能建议文档。

Specifically, any board whose MMU is enabled must disable caching for off-board memory.

任何启动MMU的内存块做板下共享内存的时候必须禁用缓存功能。

The configuration of VxWorks includes a conditional compilation constant that makes it easy to select a pair of typical configurations, for instance between an off-board shared-memory pool and an on-board shared memory pool.

VxWorks的配置包含条件编译，这使得从一对典型的配置中选择一个变得很容易，比如选择板下共享内存池或者板上共享内存池。

Several problems are resolved in the system, such as the data access in the memory, parallel file access from disk, and the replacement of file data.

解决了并行文件访问的难点：内存中数据的读写，并行化磁盘读写和文件数据的替换，性能测试表明在多用户并行处理的环境中，Parfsnow++有效地提高了系统性能，特别是在文件数据的共享，文件数据的替换，以及使用大容量的统一内存对文件数据的存取等方面。

During the Voronoi tessellation on a planar point set composed of massive points, a technical scheme of dynamic data-exchange between hard disk data file and internal memory structural array designed so, that the limitation of computer internal memory storage need not be considered and the construction of massive Voronoi cells as many as hundreds thousant in number was effectively implemented.

在对"海量"点组成的平面点集进行Voronoi划分时，设计"硬盘数据文件－内存结构体数组"之间动态的数据交互方案，避开计算机内存的限制，有效实现了数十万Voronoi晶胞集合体的构造，存储Voronoi图几何信息的数据最后以文本文件的形式输出，方便Voronoi图在工程实际中的应用与二次开发。

That is, if PuTTY was installed to your Phone Memory , then you must install the fonts to your Phone Memory.

也就是说，如果腻子安装到您的手机内存，那麼您必须安装字体到您的手机内存。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
