train signal meaning in Chinese
行车信号机
Examples
- As the train speed and density is great improved , the track circuit can transmit more information to the train signal 、 the train speeding protection system or the train control system that is necessary
随着列车速度和密度的进一步提高,要求轨道电路能够向机车信号、列车超速防护系统或列车控制系统传输更多的信息。 - Digital technology : also called the digital sound recording technology , is through the computer in digital audio frequency connection , the tonic train signaling , inducts the computer , transcribes the profile document to carry on the memory , again according to needs to carry on the edition through the multi - axle sound recording software combines full document which we need , finally outputs again transcribes cd or other audio frequency form
数字技术又称数码录音技术,是通过计算机中的数字音频接口,将话筒或其他音频信号导入计算机,录制成波形文件进行存储,再通过多轨录音软件按照需要进行编辑,组合成我们需要的完整文件,最后输出录制成cd或其他音频格式。 - The work of this dissertation is focused on research of some key technics in signal design and processing of mcpc signal . the main content of the dissertation is summarized as follows : it gives a detailed description of the form of the mcpc waveform and its mathematical model , and analyses the formation and properties of phase coded sequence . it discusses the effect of signal parameters on autocorrelation , power spectra and ambiguity function in forms of single pulse and pulse train and compares different kinds of single pulse signals and pulse train signals
本文围绕着多载波相位编码信号在信号设计与信号处理的若干关键问题进行了研究,主要做了以下工作:描述了多载波相位编码信号( multicarrierphasecoded ,简称mcpc )的信号形式,给出了其数学模型,对其中相位编码序列的构成方式与特性进行了分析;从单脉冲和脉冲串两种信号形式入手,对多载频相位编码信号的参数在自相关函数、功率谱密度和模糊方程上的影响作了详细地讨论,对不同调制方式的单脉冲和脉冲串信号进行了比较。
