amplifier的音標(biāo)是[??mpl?fa??(r)]，基本翻譯是放大器，速記技巧可以是利用發(fā)音的諧音記憶。

Amplifier的英文詞源可以追溯到拉丁語(yǔ)amplus，意為“更大的”。Amplifier這個(gè)詞在英語(yǔ)中指的是放大器，通常用于放大聲音、電信號(hào)等。

變化形式：復(fù)數(shù)形式仍然是amplifiers，單數(shù)形式可以是an amplifier或者an amplified。

相關(guān)單詞：

1. amplitude：意為“振幅”，來源于拉丁語(yǔ)amplus和tude（能力）結(jié)合，表示放大的能力。

2. amplification：意為“放大”，是由拉丁語(yǔ)amplificari（意為“放大”）和tion（名詞后綴）結(jié)合而成。

3. amplitude of frequency：意為“頻率振幅”，用來描述信號(hào)在一定時(shí)間內(nèi)的波動(dòng)程度。

4. amplifier circuit：放大器電路，是電子設(shè)備中用于放大電信號(hào)的電路。

5. signal amplifier：信號(hào)放大器，用于放大微弱的電信號(hào)，常用于通信和探測(cè)系統(tǒng)中。

6. microphone amplifier：麥克風(fēng)放大器，用于增強(qiáng)麥克風(fēng)接收的聲音信號(hào)，使其更易于處理和傳輸。

7. radio amplifier：無線電放大器，用于放大無線電信號(hào)，使其能夠傳輸更遠(yuǎn)的距離。

8. amplifier tube：電子管，是一種常用的電子放大元件，常用于音頻和視頻放大器中。

9. amplifier gain：放大器增益，表示放大器能夠放大的信號(hào)強(qiáng)度。

10. amplifier efficiency：放大器效率，表示放大器在特定條件下能夠產(chǎn)生的有效輸出功率與輸入功率之比。

英文小作文：

Amplifiers are essential components in modern electronic devices, as they are used to increase the strength of signals and signals for transmission and reception purposes. Amplifiers can be divided into different types, such as audio amplifiers, signal amplifiers, voltage amplifiers, power amplifiers, and microwave amplifiers, depending on their application and function.

In my opinion, the most important function of amplifiers is to ensure reliable and efficient transmission of signals and data between electronic devices and systems. Amplifiers can also be used to enhance the performance of speakers and microphones, allowing them to produce louder and clearer sound and voice output.

In conclusion, amplifiers are essential components in modern electronic devices and systems, as they play a crucial role in ensuring reliable and efficient transmission of signals and data between electronic devices and systems.
