A disk may contain only one extended partition.
一个磁盘可能仅包含一个扩展分区。
That’s where the extended partition comes into play.
这就是扩展分区的用途了。
Data is stored in the logical partitions within the extended partition.
数据存储在扩展分区内的逻辑分区中。
That’s because you can’t directly boot from anywhere inside an extended partition.
因为你不能从扩展分区启动系统。
An extended partition is simply a container for one, or usually more, logical partitions.
扩展分区就是一个或多个逻辑分区的容器。
You cannot store data in an extended partition without first creating a logical partition within it.
必须首先在扩展分区内创建一个逻辑分区，之后才能将数据存储到扩展分区中。
All your logical partitions must reside within a single extended partition, and so must be contiguous.
您的所有逻辑分区必须驻留在一个可扩展的分区中，因此必须是连续的。
If you need more than four partitions, give away one primary partition to create an extended partition.
如果需要超过4个分区，就需要放弃一个主分区来创建一个扩展分区。
So if you want more than four partitions on an IDE drive, you will lose one partition number to the extended partition.
因此，如果您希望一个IDE驱动器上有四个以上的分区，就需要给扩展分区分配一个分区号。
Swap space is located in the first IDE hard drive in the sixth partition, the second logical drive in an extended partition.
交换分区位于第一个IDE硬盘驱动器的第六个分区，也就是扩展分区的第二个逻辑驱动器。
Note that the extended partition is locked in this way if any of its contained logical partitions are in use, including swap space.
注意如果扩展分区其中包含的任何一个分区(包括交换空间)正在使用，那么它是以这种方式锁定的。
When more than four partitions are required, as is often the case, one of the primary partitions must instead become an extended partition.
如果需要4个以上的主分区(往往需要4个以上的主分区)，其中一个主分区就必须以扩展分区的形式出现。
In the fstab file listed above, the root file system is on the first IDE hard drive in the fifth partition, the first logical drive in an extended partition.
在上面列出的fstab文件中，root文件系统位于第一个IDE硬盘驱动器的第五个分区中，这个分区是扩展分区的第一个逻辑驱动器。
If you want to take space from a logical partition to give it to a primary partition or vice versa, you must explicitly resize the extended partition that surrounds the logical partitions.
如果您想要从逻辑分区腾出空间给主分区，您必须显式地调整围绕逻辑分区的扩展分区，反之一样。
There are three types of partition on IDE drives: primary, logical, and extended.
IDE驱动器上有三种类型的分区：主、逻辑和扩展。
pvresize extends PVs if the underlying partition has also been extended; it shrinks PV if the allocation map permits it.
pvresize：如果底层分区也已经扩展了，那么可以用这个操作扩展PV；如果分配图允许的话，它也可以缩小 PV。
Each disk holds a primary ext3 partition and a 500mb swap and a ~ 2gb ext3 partition inside the Extended volume.
每块磁盘有主要的ext 3分区和500MB的交换区和扩展卷中的2gb的ext3分区。
The remaining space on the card is dedicated to a third extended file system (ext3) partition.
卡上的剩余空间分配给一个thirdextendedfilesystem (ext3)分区。
Cannot create extended DOS partition without primary DOS partition on disk.
在盘中没有主dOS分区，故不能建立扩展分区。
To improve the performance of object tracking, a particle filter algorithm was proposed which(uses) state partition technique and parallel extended kalman filter to construct proposal distribution.
为了进一步提高目标跟踪的性能，采用一种新的建议分布构造方法，即利用状态分割技术和平行扩展卡尔曼滤波技术构造建议分布。
All available space in Extended DOS partition is assigned to logical drives.
全部扩展DOS分区上的可用空间都被指定给逻辑驱动器。
Cannot delete extended DOS partition while logical drive exist.
当逻辑驱动器存在时，不能删除扩展DOS分区。
All logical drives deleted in extended DOS partition.
扩展DOS分区中的所有逻辑驱动器被删除。
