查询词典 oscillators

This system has been applied to the stability measurement of the crystal oscillators and the rubidium clocks as well as the caesium clocks with zero dead time and non-offset frequency, and also to the calibration of the secondary frequency standard.

其测量精度目前约为2×10~(-12)τ~(-1)(0.1s≤τ≤1000s)，已应用于晶振、铷钟和铯钟的无间隙时间不偏调频率的稳定度测量以及次级频标的校频中。

Through the noise analysis between circular oscillators composed of general differential amplifer element and of capacitive coupling differential amplifier element, it is found that the later,due to its band-pass and dynatron characteristics,provides a better anti-noise performance,which can be used in VCO circuits having a high requirement on frequency stability.

通过对采用由普通差分放大器单元和容性耦合差分放大器单元构成的环行振荡器的噪声分析得出，由容性耦合差分放大器单元构成的环行振荡器，因其带通特性和负阻特性而具有较好的抗噪声能力，可用于对频率稳定度有较高要求的VCO等电路中。

We study the interaction between coupling strengths, delay and concavity for a pair of two Mirollo-Strogatz-type oscillators.

我们研究了对於两个Mirollo-Strogatz-type的摆动器系统中耦合强度系数、延迟时间和其函数凹凸性之间的互相影响。

Almost all digital electronic circuits now rely on this phenomenon in the form of crystal oscillators.

The automation has been largely enhanced on crystal oscillators assembly-line using machine vision technique.

摘 要：随着晶振装配生产线中视觉检测技术的引入，很大程度上提高了自动化检测水平。

For nonlinear harmonic oscillators systems of coordinate coupling and momentum-coupling, one obtains a group differential equations for physical parameters about flow parameter by the numerical analysis method, one finds this method can diagonalize the Hamiltonian.

通过数值分析物理参数随流参数变化规律，给出了对角化的哈密顿量。

Different from the case of only one coupled periodic oscillator, in two oscillators one or the other harmonic oscillator will entrain alternately (or they will entrain exclusively).

典型的同步系统，如驱动-响应同步，设它们各自混沌信号分别为x1，x2，经过足够长的暂态后如有x1=x2，则可以认为系统达到完全

The essential difference is that the spectrum analyzer, being designed for laboratory use, is designed to cover an extremely wide frequency range with widely adjustable tuning range, bandwidth, etc. It uses one or more sweeping local oscillators Fig.

区别在于频谱分析仪被设计成是实验室使用，设计成是带有很大可调范围和带宽等并覆盖非常大频率范围的仪器。

One is the epidemic spreading; the other is the synchronization of coupled oscillators. First, concepts of complex networks are introduced to make the thesis facilely.

研究传染病(或者计算机病毒、谣言、信息等)在网络上的传播规律，并采取相应的措施进行预防和控制，是网络动力学研究的一个基本方向。

To compare with other oscillators, the figure of merit is calculated, which is about -173.2dBc/Hz.

为了与其他振荡器比较，还通过计算得到了相位噪声优值，约为-173.2dBc/Hz。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
