定时

SOA can be used in the dispersion compensation in fiber transmission system, all-optical regeneration, optical time division multiplexing, and used as preamplifier, in-line amplifier, boost amplifier in signal transmission. SOA can be also used as wavelength converter, optical switch. In signal procession, nonlinear optical loop mirror based on SOA can be used in optical pulse reshaping, and used as high rate (100Gbit/s) demultiplexer, and optical correlator for optical data retiming.

在信息传输方面，SOA用于色散补偿、全光再生和光时分复用和前置放大、线路放大、功率放大等；在信息交换方面，SOA用于波长转换、光开关等；在信号处理方面，SOA构成的非线性光环形镜用于光脉冲整形、光数据信号再定时的光相关器和高速（100Gbit/s）解复用等。

A critical task of such a receiver is the recovery of the clock embedded in the data stream. Then, the recovered clock retimes the data and removes the jitter and distortion in the data.

光接收机的一个重要任务就是从接收到的数据信号中提取出时钟信号，并通过时钟信号重新定时数据信号，减少抖动和干扰。

If the Layer 1 devices are active, the actually are regenerated and retimed.

如果第一层部件是有源的则比特实际上要再生和重新定时。收发信机也是有缘设备。

Select that option, and then press OK when it tells you that everything will need to be restarted.

选择该选项，然后按确定时，它会告诉你，一切都将需要重新启动。

In ${repos} are rotated weekly?

当在 ${repos}中每周执行定时任务时，您希望保留多少过去的历史文件？

The application of this technique in data access object is implementd through repacking the interface between application program and database system.

现代数据管理几乎都是以数据库作为其核心的，同时，现实世界中越来越多的应用要求对数据的&定时&存取和对&短暂有效&数据的存取，实际操作越来越趋于复杂，软件的设计也越来越复杂，数据库访问和处理的速度已经越来越重要了，实时数据库在这种情况下提了出来。

This board uses two chips, six channels A/D converter and phase locking synchronous technology for collecting three-phase voltage and current signals in timing and equal-time cycle sampling ways, and the gained data make more reasonable for power quality norm analysis.

并采用了两片六通道高速A/D转换器和运用了锁相同步技术，对三相电压和电流信号能进行定时采样和等间隔采样，这样得到的数据对于下一步电能质量指标进行分析更为合理。
