该装置由振荡器、开关电容、二阶跟踪系统、数字开关系统、功放电路及亥姆霍兹线圈组等部分组成，可以产生频率、强度连续可调的旋转磁场。

It is very simply a hi-fi system – with turntable, amplifier, and speakers – cast in concrete.

这是非常简单的音响系统，转盘，放大器-和扬声器-一成不变的。

Nowadays, people emphasize high power and high efficiency as well as high fidelity feature of audio power amplifier.

人们在追求高保真度音频功放的同时，也希望功放有大的输出功率和高效率。

But, because mobility of raceway groove of Si CMOS parts of an apparatus is low, bring about parts of an apparatus cross guide the Si parts of an apparatus that falls under same size, so gain of its open loop also is less than the Si operation amplifier of identical structure and dimension.

但是，由于Si CMOS器件沟道迁移率低，导致器件的跨导低于相同尺寸下的Si器件，所以其开环增益也小于相同结构和尺寸的Si运算放大器。

And yes, it is possible to achieve that kind of output impedance in a power amplifier.

当然我要提醒你：我们是可以在功率放大器上做到这样的输出阻抗的。

The laser and optics properties of several kinds of laser glass have been discussed. A new method is pointed out to increase the output energy of power-limited laser that is high gain glass and low nonlinear refractive index coefficient n2 glass used in an amplifier together.

在分析几种激光基质材料的光谱和激光特性的基础上，提出了在功率受限型激光装置的主放大级中混合使用高增益激光玻璃和低非线性折射率n2玻璃的新思路，以期在降低n2的基础上提高激光装置的系统输出能力。

This simple definition ignores the fact that amplifier output impedance usually varies considerably across the audio band, increasing with frequency as the negative feedback factor falls; this indicates that the output resistance is actually more like an inductive reactance.

这个简单的定义忽略了功放输出阻抗通常是随着音频带而变化，负反馈因素降低的时候频率也增加这一事实。这就意味着输出电阻实际上更像是一个电感电抗。

To suit it for this usage, the ideal operational amplifier would have infinite input impedance, zero output impedance, infinite gain and an open-loop 3 dB point at infinite frequency rolling off at 6dB per octave.

为了得到这样的特性，理想 OP 应该有无限大的输入阻抗，0 输出内阻抗，无限大的增益，无限大的开环增益带宽(3dB 带宽)，以及其 6dB/每 2 倍频程的频率滚降。

The system is made up of PXI-6251 module collecting the dataduring the experiment, SCXI-1520 module adjusting the relaxing strain signal, FCS load inphase with multicenter system providing the pull during the demarcate experiment, sensorsmeasuring the strain and the pull, charge amplifier adjusting the relaxing pull signal, and soon.

组建了基于PXI总线的复合材料残余应力测试系统，此系统包括数据采集模块PXI-6251，应变信号调理模块SCXI-1520，FCS多通道协调加载控制系统、应变花和压电力传感器、电荷放大器等。

These two pairs exhibit different offsets and bias currents, so when the applied input common-mode voltage changes, the AMPLIFIER input offset voltage and input bias current does also.

由于这两个差分对有不同的失调电流和偏置电流，因此加到输入共模电压变化，放大器的输入偏置电压和输入偏压电流也跟着改变。

We have limited budget let me know if you can do this competitively.

我们有限的预算让我知道如果你能做到这一点竞争力。

We don't know how other critters breathe--lizards, for example.

我们还不知道诸如蜥蜴之类的动物如何呼吸。
