In chap 10 . we describe the local resources management the emphases are the design and management of the file storage pointer table especially keeping the information in memory and disk synchronous which include timer synchronization and remedy synchronization .

第九章描述了本地资源管理，重点在于文件存储指针表的设计和管理，特别是保持内存和磁盘信息的 同步机制，包括 定时同步和补救同步。

Synch-sampling is an ideal AC sampling method it may appear deviation ( sampling synchronous deviation ) because of the limitation of minimum timing unit of timer and variety of signal frequence .

理想的交流采样是同步采样，但是由于信号周期的飘移和 定时器最小定时单位的限制，同步采样会出现偏差（采样 同步偏差）。

Synchronous Timer for Synchronization / Data Buffer System

同步与数据缓冲系统的 同步 定时器

Proposes a method of Two-section Double-speed synchronous sampling . It has effectively restrained error of the sampling period and made it not exceed one Td ( Td are a resolution of the timer ) . The deviations between actual and theoretic sampling point are controlled within one Td .

提出了一种非均匀 同步采样方法，它不仅有效地 抑止了采样周期误差，而且实际采样点与其理论采样点间的偏离也被有效控制在1个Td之内。

According to the synchronous signal of the measuring and control information using high-precision timer on information measuring and control card the accurate adjustment of exposure time is carried out through correction of exposure signal of the camera by software with video sampling card .

根据测控信息 同步信号及其对视频采集时刻的规定，以测控信息采集卡上高精度 定时器为 时钟，由视频采集卡通过软件修正摄像机曝光信号，实现对曝光时刻的精密调节。

The Synchronous timer is used as a major Component of the CDAS S / DB System .

同步 定时器是CDASS／DB系统的重要部件。

Synchronous deviation caused by limitation of the timer has already been studied by numerous scholars however Synch-sampling in the instance of signal cycle instability has been less discussed .

定时器最小 定时引起的 同步偏差已有众多学者研究，信号周期飘移下的同步采样则较少有人涉足。
