查询词典 analog signals

The results of the study showed that:① Using dozens of kilograms of explosives the signal can be detected at distances up to 200 km;②Active source has a certain degree of repeatability among different shots;③This paper presents the following shooting mode and signal detection method based on the similarity of different shots: In light of the similarity between the signals of big shot and small shot, this paper presents a cross-correlation method using signal from big shot signal with high SNR and small shot signal to detect weak small shot signal, the method can effectively detect the small shot signal and pick up the start time of phase, this method can help us make full use of past seismic exploration data records.

野外实验采用1次大当量激发和16次小当量激发，研究结果表明：①有可能利用数十公斤当量的炸药实现200km距离的探测；②在激发条件相同时，不同当量的激发波形滤波后存在一定的相似性；③依据人工震源可重复性采用以下的激发组合方式和处理方法能够有效提高信噪比：针对大当量激发与小当量激发波形的相似性，利用大当量激发的波形作模板与小当量激发的波形作相关，可判断台站是否接受到小当量激发的信号并检测其震相到时信息。

The system can be assisted by a tripod-mounted signal relay system, which can be carried by crewmembers in the mountain regions to receive and re-send the image signals.

系统能被三脚架安装的信号中继系统辅助，能被成员携带到山区去接收和再传送图像信号。

We analyzed the air gun signals in the 185Km-long seismic line. And the records showed that the air gun signal is full of seismic phase information. Based on these phases, we developed the P-wave velocity model for this area and find an obvious low-velocity layer, which is coherent to what people obtained from other geophysical methods in this area.

我们分析了气枪激发信号在长185km测线上的记录，拾取包含的丰富震相信息(如Pg，Pn，PmP等)，并在此基础上反演了该地区的P波速度模型，模型结果显示该地区存在明显的低速层，这与在该地区进行的其他地球物理探测结果一致。

Each test signal of tank gun control test system usually has random disturbance , real-time recurrence filtering for test signals is performed by means of Kalman filtering.

火炮控制检测系统各检测信号大多含有随机干扰，利用卡尔曼滤波可对检测信号进行实时递推滤波。

This system consists of a network of towers that receive GPS signals and transmit a corrected signal by beacon transmitters.

该系统由一个网络的塔接收GPS信号和传输信号的更正灯塔发射机。

By choosing proper threshold and appling a non-linear shrinkage rule to the wavelet coefficients, the noise in signals can be well restrained, and choosing appropriate shrinkage function in WaveShrink is one of the most basic issues, which will have great effect on denoising.

其中，选取合适的阈值函数是该方法最基本的问题之一。

The time series in Magnetotelluricscontains multiple spectra and often has unneeded natural electromagnetic signals and the interference of 50 Hz and its harmonic frequency.

大地电磁测深法野外观测得到的原始资料是包含多种频谱的时间序列，这种时间序列中常包含不需要的信息和50 Hz及其谐波的干扰。

Tne functions of microwave towers are receiving and boosting signals and sending them to the next station.

微波塔的功能是接受和放大信号并将其转至下一站。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.

译者虽然由原语文化可以自由穿透的玻璃球变成了译语文化可以自由穿越的玻璃球，但译者认知过程中的个体体验在翻译研究中依然缺席，译者依然仅仅是一个没有躯体体验的主体。

Chillingly, he claimed our technology is 'not nearly as sophisticated' as theirs and "had they been hostile", he warned 'we would be been gone by now'.

令人毛骨悚然的，他声称我们的技术是'并不那么复杂，像他们一样，和"如果他们敌意"，他警告说，'我们将现在已经过去了。
