FOREWORD前言

本書以提升電氣自動化技術(shù)、機(jī)電一體化技術(shù)等相關(guān)崗位專業(yè)英語技

能為目標(biāo)確定教學(xué)模塊，結(jié)合技術(shù)發(fā)展動態(tài)和技術(shù)綜合應(yīng)用，組織英文

內(nèi)容，具有較強(qiáng)的專業(yè)針對性；以學(xué)生能夠看懂的英文圖紙、軟件界面、

設(shè)備操作面板、設(shè)備說明書、企業(yè)官網(wǎng)與產(chǎn)品宣傳手冊為教學(xué)內(nèi)容，使

專業(yè)英語的學(xué)習(xí)簡單化、實用化。本書最大限度地吸納項目化的教學(xué)理

念，實現(xiàn)了專業(yè)技術(shù)和專業(yè)英語的有機(jī)融合。全書從簡單的電工電子元件、

儀表設(shè)備入手，涉及工業(yè)控制設(shè)備的產(chǎn)品手冊、系統(tǒng)構(gòu)造規(guī)則等，以圖

片的形式呈現(xiàn)，簡單易學(xué)。

本書分為6章，共19個單元。電路理論基礎(chǔ)模塊主要是以圖文并茂

的形式介紹元器件、儀表、參數(shù)等英文表述；電氣控制系統(tǒng)、工業(yè)控制系

統(tǒng)模塊兼顧專業(yè)基礎(chǔ)理論知識，培養(yǎng)學(xué)生理解設(shè)備的安裝和閱讀產(chǎn)品手

冊的能力；電力系統(tǒng)保護(hù)模塊主要使學(xué)生掌握電力保護(hù)裝置的產(chǎn)品名稱；

機(jī)電一體化技術(shù)模塊主要使學(xué)生了解典型機(jī)電設(shè)備各部件的英文描述；拓

展部分選取了相關(guān)閱讀材料，可提高學(xué)生閱讀英文文獻(xiàn)的能力。

本書相較于第一版在內(nèi)容選取上涉及自動應(yīng)用的多個領(lǐng)域，增加了機(jī)

器人、電梯這些典型的自動化設(shè)備的內(nèi)容，同時介紹了其行業(yè)的優(yōu)秀企業(yè)。

教師可根據(jù)專業(yè)實際和課時數(shù)自由選取合適的單元組織教學(xué)內(nèi)容。

本書由姚薇、錢玲玲主編，并負(fù)責(zé)全書內(nèi)容的選取與構(gòu)架安排。王超、

薛嵐在本書的編寫中提出了寶貴意見，特此感謝。

由于編者水平有限，書中難免存在不足和疏漏之處，敬請讀者批評指正。

電解電容器使用注意事項

（1）在電路回路中如不清楚或不明確線路的極性時，則建議使用無極性電解電容器。

（2）電解電容器的工作環(huán)境溫度不能超過規(guī)定的使用溫度范圍。

（3）電解電容器應(yīng)儲存于低溫及干燥場所，如儲存期較長，則使用前應(yīng)用額定電壓對其重

新校驗。

（4）電烙鐵等高溫發(fā)熱裝置應(yīng)與電解電容器塑料外殼保持適當(dāng)?shù)木嚯x，以防止過熱造成塑

料套管破裂。

（5）對導(dǎo)線、端子，如施加超過規(guī)定的力，將會破壞電解電容器的內(nèi)部結(jié)構(gòu)。
