但是NEC已经开发出了一种新的谐波调谐放大器，可以从其它方面使这些标准设备的效能增强45%。

Add a good sense of timing and essentially you've got everything you need in a headphone amplifier.

此外它的速度感也很好，基本上你对耳放所要求的，它都能满足了。

I have no real opinion as to the sound of the Phoenix as a Headphone amplifier.

我没有真正关于凤凰作为耳放的观点。

This device, which is composed of oscillator, switching capacitor, second-order tracking system, digital switching system, power-amplifier circuit and Helmholtz coils , can produce rotating magnetic field whose frequency and strength can be adjusted continuously.

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。

The system can be widely used in belt weighing and batching process control,etc.

介绍了基于智能模糊控制的嵌入式配料系统的设计方法，对模糊PID控制过程和系统调零作了重点的讨论，同时给出了PID控制的程序流程图和系统定长调零子程序。

"I dunno," she answered,"but if you show me aroun', I'll recognize it from the lighthouse just outside the porthole."

"我不知道，"她回答说，"如果你能带我转转，我能认出来的，因为灯塔就在舷窗外。"
