扇区

In a soft-sectored disk, this will be an index hole ; in a hard-sectored disk, it will be a sectored hole.

在软扇区磁盘中，这应是一个指示孔；在硬扇区磁盘中，这应是一个扇区孔。

We see the signature value of 0x504d in bytes 0 to 1 and the number of partitions in bytes 4 to 7, which is 10 (0x0000000a). Bytes 8 to 11 show us that the first sector of the disk is the starting sector for this partition and that its size is 63 sectors (0x3f). The name of the partition is "Apple," and the type of partition is "Apple_partition_map." Bytes 88 to 91 show that no flags for this partition are set.

我们可以看到0-1字节处签名值为0x504d，4-7字节处的分区总数为10，8-11字节处表示硬盘的第一扇区是该分区的起始扇区，它的大小为63扇区（0x3f），分区名称为"Apple"，分区类型为"Apple partition map"，88-91字节处显示该分区无设置标志。

Sector is the smallest physical disk storage unit, but the operating system unable to carry out a large number of addressable sectors, the sector adjacent to the operating system will combine to form a cluster, and then the management of clusters.

扇区是磁盘最小的物理存储单元，但由于操作系统无法对数目众多的扇区进行寻址，所以操作系统就将相邻的扇区组合在一起，形成一个簇，然后再对簇进行管理。

Sectorization is extensively used in cell communication systems. A scheme combined smart antenna and sectorial antenna is proposed which is an effective method to realize sectorization together with smart antenna.

扇区化是蜂窝系统重要的覆盖方式，基于这种考虑提出了一种TD-SCDMA系统实现扇区化智能天线的方法—扇区化智能天线(SSA-Sectoral SmartAntenna)，该方法有效的解决了TD-SCDMA系统智能天线扇区化问题。

Windows9x series using a FAT file system, due to the form of links, at the beginning of the beginning of the various sectors of documents stored in a row, but with the additional documentation to establish, delete and other operations, the newly created file on the beginning of the distribution of in non-consecutive disk sectors, the middle of the distribution sector there are other documents and / or space sector.

Windows9x系列用的是FAT文件系统，由于采用链接表的形式，在刚开始的时候文件的各个扇区是连续存放的，但随着更多文件建立、删除等操作，新建立的文件就开始分布于不连续的磁盘扇区，中间分布有其它文件的扇区和/或空扇区。

The W-CDMA overlay GSM means use tuneable notch filters at the CDMA transmitters and receivers.The spectrum of notch filters is just the spectrum of GSM.

窄带覆盖的基本原理是N-CDMA信道不与GSM频带在同一小区的同一扇区重叠，而是和N-CDMA扇区相邻小区里的，且与该扇区不相邻的GSM扇区重叠。

Fdisk is not only a zoning process, it has a very convenient feature to restore the main boot sector, but only modify the main boot sector, other sectors of the write operation is not carried out, so for those who are still using Windows 9x friend the case of no doubt is a very good tool to repair the partition table.

Fdisk 不仅是一个分区程序，它还有着非常便捷的恢复主引导扇区功能，而且它只修改主引导扇区，对其他扇区并不进行写操作，因此对于那些还在使用 Windows 9x 的朋友而言无疑是个非常理想的分区表修复工具。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
