结果表明，Hilbert曲线的确能够更好地根据拓扑聚集数据，与Z 排序相比，它可以减少 1.5% 的数据物理读。
The result shows that indeed the Hilbert curve clusters the data better according to their topology, giving us an additional 1.5% less data physical reads, compared to the Z-ordering.
在基线上，我们看到必须从物理设备多读11%的页。
At the bottom line we see an additional 11% pages had to be read from the physical device.
结果，它一般需要大量的物理磁盘读操作来保证实现一致的低事务响应时间。
As a result, a high number of physical disk reads are usually required to ensure consistently low transaction response times.
一个“为消遣而读医学期刊”的物理学家，毫无疑问是个拥有好奇心的人，他的优势就是拥有全新的视角。
A physicist who “read medical journals for fun” is definitely a curious person. And he had the advantage of a fresh perspective.
可能由于短区段而增加操作时间的操作包括：查找区段、逻辑地址到物理地址的映射、轻量扫描、存档、预读、以及检查点刷新。
The operations that may take longer with short extents include: finding extents, mapping logical to physical addresses, light scans, archives, read-ahead, and checkpoint flush.
我读的是物理系。
Cohen原来在哈佛读的是物理学，后来又到加州伯克利去读理论计算机学的硕士。
Cohen was a physics major at Harvard, and he went on to study theoretical computer science at UC Berkeley, earning a master's.
介质故障是磁盘，导致读失败或写入运行数据库所需磁盘文件失败的一个物理问题。
A media failure is a physical problem with a disk that causes a failure of a read from or write to a disk file that is required to run the database.
它是一种“内容实体”。例如读英文版的“低温物理学”、“神经生理学”，文字与语言所占的角色是很次要的。
It forms the content itself, like English edition of "Low-Temperature Physics" or "Nerve Physiology." In this case, the role of language and style is only secondary.
第12.6节的场景，描述活动的物理备用数据库为读/写报告数据库，然后与主数据库重新同步数据库。
Section 12.6for a scenario that describes activating a physical standby database as a read/write reporting database, and then resynchronizing the database with the primary database.
写时拷贝技术允许父进程和子进程读同一个物理页面。
The Copy On Write technique allows both the parent and the child to read the same physical pages.
何大一：物理、医学都属于科学方面的，美国跟中国不一样，美国是你先去读大学，大学毕业以后再去读医学院。
David ho: physics, medical science are the United States with China does not like you go to the United States is the University of Reading, after graduating from college and then medical school.
盖茨笑称，这位已故作者的散文集会让你在火车或者飞机上“看起来超级聪慧”，因为你看上去是在读物理，即便你其实读的是网球。
Gates jokes that the late writer's collection of essays "will make you look super smart" on a train or plane, as you'll appear to be reading about physics, even when you're reading about tennis.
物理实验常用仪器的读数规则可归纳、简化为两种：估读和直读，借助这些规则可规范和简化不确定度的评定。
There are two methods to read data from common instrument in physics experiment: the approximate read and direct read. We disscussed the rules to read data and to evaluate the error range.
