繼電器,第一眼看到就感覺(jué)很懵逼,“繼”是什么意思?將Relay翻譯成繼電器有點(diǎn)莫名其妙,Relay本質(zhì)上是一個(gè)傳達(dá)信號(hào)的裝置,但從中文字面看不出任何跟Relay相關(guān)的意思。隨著科技的發(fā)展,外來(lái)語(yǔ)越來(lái)越多,很難有和適合的詞匯與此對(duì)應(yīng),因此,還是看英文原版才能更好地理解這些專(zhuān)業(yè)詞匯。

relay noun [C] (EQUIPMENT)
a device that reacts to a small change in an electrical current by moving switches or other devices in an electrical circuit (通過(guò)移動(dòng)電路中的開(kāi)關(guān)或其他設(shè)備對(duì)電流的微小變化做出反應(yīng)的設(shè)備)中繼設(shè)備
2.2 名詞解釋
A relay is an electrically operated switch that uses an electromagnet to open or close any electrical circuit. In other words, We can say that A Relay is an electromechanical switch that has the ability to turn ON or OFF any electrical circuit. It consists of a flexible moving mechanical part that can be controlled electrically through an electromagnet.繼電器是一種電動(dòng)開(kāi)關(guān),它使用電磁鐵打開(kāi)或關(guān)閉任何電路。換句話說(shuō),我們可以說(shuō)繼電器是一種機(jī)電開(kāi)關(guān),能夠打開(kāi)或關(guān)閉任何電路。它由一個(gè)靈活的移動(dòng)機(jī)械部件組成,可以通過(guò)電磁鐵進(jìn)行電氣控制。

While we use normal switches to open and close any electrical circuit manually, Relay is also a Switch that connects and disconnects circuits. But instead of manual operation, the Relay uses an electrical signal to control the circuit’s ON-OFF operation. Relays are used to controle a high-powered circuit using a low-power signal.我們使用普通開(kāi)關(guān)手動(dòng)打開(kāi)和關(guān)閉任何電路,但繼電器也是一種連接和斷開(kāi)電路的開(kāi)關(guān)。但是,繼電器不是手動(dòng)操作,而是使用電信號(hào)來(lái)控制電路的ON-OFF操作。繼電器用于使用低功率信號(hào)控制高功率電路。
3 中文解釋
繼,是連續(xù)、接著的意思。相關(guān)詞語(yǔ):繼續(xù)、繼任、繼承、繼武(足跡前后相接,喻后人接續(xù)前人的事業(yè))、繼往開(kāi)來(lái)、前仆后繼。

繼電器(英文名稱:relay)是一種電控制器件,是當(dāng)輸入量(激勵(lì)量)的變化達(dá)到規(guī)定要求時(shí),在電氣輸出電路中使被控量發(fā)生預(yù)定的階躍變化的一種電器。它具有控制系統(tǒng)(又稱輸入回路)和被控制系統(tǒng)(又稱輸出回路)之間的互動(dòng)關(guān)系。通常應(yīng)用于自動(dòng)化的控制電路中,它實(shí)際上是用小電流去控制大電流運(yùn)作的一種“自動(dòng)開(kāi)關(guān)”。故在電路中起著自動(dòng)調(diào)節(jié)、安全保護(hù)、轉(zhuǎn)換電路等作用。

由于翻譯很難做到意思完全對(duì)應(yīng),另外時(shí)效性也比較差,因此,學(xué)習(xí)前沿先進(jìn)科技有限看英文原版教材,英文讀起來(lái)雖然費(fèi)點(diǎn)事,但內(nèi)容更容易理解。
