查询词典 analog signals

We compose a neural network in which the input signals are the frame substructure natural frequencies and mode shapes, and output signals are the submatrix scaling factor.

框架子结构在动载作用下的自振频率和模态作为网络的输入，子矩阵参与系数作为网络的输出，用Levenberg一Marquardi算法训练网络。

By the use of this method, we can divide any ω-circulant signal into a summation of many sub-signals; especially among those sub-signals, there are many subseries of which their period is just equal to 1, which are actually the frequency elements of the original ω-circulant signal.

通过使用这种方法，我们可以将任意ω-循环信号分解成一序列子信号；特别地，这些子信号可以是周期为1的，这时的子信号实际上相当于Fourier变换中信号的频谱。

The invention is used for realizing the frequency-division multiplexing synchronical transmission of the broadcasting TV signals, which can decrease the same-frequency interference of the crossing area of the broadcasting TV carrier signals and reduce system cost, thereby causing the system debug to be simpler.

本发明用于实现广播电视信号的频分复用同步发射，降低广播电视高频载波信号的相交区域的同频干扰，降低系统成本，使得系统调试更加简单。

The signal degradation is usually modeled by a linear system. To restore the original signals from the distorted and noisy signals, we need to solve the linear system of equations.

信号退化的过程一般可用线性系统模型来表示，要从退化的信号中恢复出原始信号，必须对其线性系统的方程组进行求解。

New technology has made it possible that a normal telephone subscriber who signed with IP telephony provider,can dial in a gateway which converts the voice signals into packets.The packets will be transported over IP network and will be converted back to voice signals through the gateway on the other end.The called party can receive the call from a PSTN phone whatever signed with IP telephony provider or not.

新技术已经使其成为可能，即一个向IP电话服务商登记的普通电话用户可以拨通一个网关，该网关使语音信号转化为信息包，信息包将通过IP网络转输并通过另一端的网关转回语音信号，被叫方可以从一台无论是否向IP电话服务商登记的PSTN电话收到呼叫。

The reason is that every methods ,based on second-order statistics, impose many preconditions for signals and geological models, like supposing pratical signals are Gauss ones, noise is Gauss white noise, and telluric system is linear non-minimum phase one. But practical situations are not like this.

其原因是基于二阶统计量的各种方法，对信号和地质模型作了许多假设和要求，如假设信号为高斯信号，噪声为高斯白噪声，大地系统为线性非最小相位系统，但实际情况并非如此。

In 2005, a group of MIT students conducted a formal study using aluminum foil and radio signals. Their surprising finding: Tinfoil hats may actually amplify radio frequency signals.

2005年，一群麻省理工学生用锡箔和无线电信号进行了正式研究，他们惊讶地发现：锡帽实际上可能放大无线电频率信号。

The system collects and saves running state signals and these signals are diagnosed by fault diagnosis expert program. Then diagnosis results are sent to display screen in order to instruct trainman to keep locomotive running safety.

该系统采集并存储机车运行状态信号，由故障诊断专家程序对信号进行诊断，并将诊断结果发送到显示屏指导乘务员维护机车安全运行。

The selected subject gives a general design of the grating auto testing instrument, by using the characteristics of orthogonal A and B signals output by optical encoder and symmetrical black and white linear transmission grating bar, and analyzing the means of the high electrical level of signals change to number of counter pluses.

本文通过分析了编码器输出两路信号的正交性(相位相差90°)与直线透射式光栅黑白栅条的分布均匀性的特性，应用把高电平宽度转换为计数脉冲的个数的测试方法，给出了光栅自动测试仪的总体设计方案。

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。
