繼電器,第一眼看到就感覺很懵逼,“繼”是什么意思?將Relay翻譯成繼電器有點莫名其妙,Relay本質上是一個傳達信號的裝置,但從中文字面看不出任何跟Relay相關的意思。隨著科技的發展,外來語越來越多,很難有和適合的詞匯與此對應,因此,還是看英文原版才能更好地理解這些專業詞匯。
1 英語原意
繼電器:Relay
2 英文解釋
2.1 詞語解釋
relay verb [ T ]
to repeat something you have heard, or to broadcast a signal, message, or programme on television or radio傳達,轉發;播放;轉播
I was told the news first and then I relayed it to the others.
我是第一個被告知這消息的人,接著我又轉告了其他人。
relay noun [C] (TEAM)
a group of people who continue an activity that others from the same team or organization have been doing previously接替的一組人;輪換的一隊人
Relays of workers kept the machines going through the night.
工人們輪班工作,機器徹夜運轉。
(also relay race)
a running or swimming race between two or more teams in which each person in the team runs or swims part of the race(跑步或游泳的)接力賽
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 (通過移動電路中的開關或其他設備對電流的微小變化做出反應的設備)中繼設備
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.繼電器是一種電動開關,它使用電磁鐵打開或關閉任何電路。換句話說,我們可以說繼電器是一種機電開關,能夠打開或關閉任何電路。它由一個靈活的移動機械部件組成,可以通過電磁鐵進行電氣控制。
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.我們使用普通開關手動打開和關閉任何電路,但繼電器也是一種連接和斷開電路的開關。但是,繼電器不是手動操作,而是使用電信號來控制電路的ON-OFF操作。繼電器用于使用低功率信號控制高功率電路。
3 中文解釋
繼,是連續、接著的意思。相關詞語:繼續、繼任、繼承、繼武(足跡前后相接,喻后人接續前人的事業)、繼往開來、前仆后繼。
繼電器(英文名稱:relay)是一種電控制器件,是當輸入量(激勵量)的變化達到規定要求時,在電氣輸出電路中使被控量發生預定的階躍變化的一種電器。它具有控制系統(又稱輸入回路)和被控制系統(又稱輸出回路)之間的互動關系。通常應用于自動化的控制電路中,它實際上是用小電流去控制大電流運作的一種“自動開關”。故在電路中起著自動調節、安全保護、轉換電路等作用。
在電氣控制領域,最常見的就是電磁繼電器,PLC輸出端可以直接連接在電磁繼電器輸入控制端,由PLC控制繼電器開合,進而實現小電壓控制大電壓。
由于翻譯很難做到意思完全對應,另外時效性也比較差,因此,學習前沿先進科技有限看英文原版教材,英文讀起來雖然費點事,但內容更容易理解。
