1·A rail automatic block signal system based on the field bus technology is introduced, and its reliability design is explained specially.

介绍一种基于现场总线技术的铁路自动闭塞系统，并就其可靠性设计作了重点阐述。

2·The paper gives solutions to the problems with lighting circuit of permissive aspect of block signal of existing automatic block section according to relevant specifications.

通过对现有自动闭塞区间通过信号机容许信号点灯电路存在问题的分析，根据相关规范，提出解决办法。

3·One space after a period is plenty to signal the end of a sentence. It also keeps the text block even.

一个空格足够区分二个句子，同时还能保证文本块的连续性。

4·A standard configuration is for a carrier is to use half of each block to send a signal, and half to receive (outbound and inbound traffic).

运营商的一种标准配置是使用一半的块来发送信号，另一半接收(即下行和上传通道)。

5·By forcing a timing reacquire, the front end block resets and hunts for a video signal, thus ensuring the speedy locking to a new video source.

通过强制再获取时序，前端模块复位并搜索视频信号，从而确保迅速锁定新的视频源。

6·The two rails are not only signal lines of track circuits, but also loop current line of locomotive traction current in electrified railway block.

电力牵引区段的两条钢轨，既作为轨道电路的通道来传输信号电流，又作为牵引电流的回路来传送牵引电流。

7·Such an object exists and retains its last-stored value during the execution of the block and while the block is suspended (by a call of a function or receipt of a signal).

这种对象将在该块的执行期间以及当该块被挂起时一直存在，并总保持其最近保存的值。

8·Small sugar fragments can set off a signal cascade that increases inflammation and scar formation. A small peptide can block this process and allow scar-free healing

糖碎屑能引发皮肤快速发炎和形成疤痕的显著层叠。

9·One detection design block diagram and algorithms for low S/N DS/SS signal are presented in this paper.

本文对低信噪比直接序列扩频（DS／SS）信号的检测提出了设计方案和算法。

10·But there are drawbacks: block the light and you block the signal.

但是它也有弊端：遮住光源，就遮住了信号。
