MechanicsFundamentofProcessEquipment過程裝備力學(xué)基礎(chǔ)（朱孝欽）（英文版）

本書著重介紹過程裝備研究或設(shè)計中所涉及力學(xué)方面的基本理論和基本知識，全書共8 章，包括緒論、彈塑性力學(xué)概論、彈性力學(xué)的基本概念及其基本方程、彈性力學(xué)的平面問題、塑性力學(xué)基礎(chǔ)簡述、旋轉(zhuǎn)薄殼的基本理論、厚壁圓筒的彈塑性力學(xué)分析、薄板理論等內(nèi)容。
本書可作為過程裝備與控制工程專業(yè)本科或研究生“過程裝備力學(xué)基礎(chǔ)”雙語課程教材，也可供相關(guān)專業(yè)的工程技術(shù)人員參考。

雙語教學(xué)是隨著我國高等教育改革的不斷深入而產(chǎn)生的，并且呈現(xiàn)出課程門數(shù)不斷增加的發(fā)展趨勢。雙語教學(xué)既可以在教授科技知識的同時幫助學(xué)生穩(wěn)步提升外語應(yīng)用能力，還可以吸取國外一些好的教學(xué)方法，因此，近年來得到了較快的發(fā)展。
對于過程裝備與控制工程專業(yè)的本科教學(xué)，由于國外高等工科院校沒有對應(yīng)的專業(yè)，因而相應(yīng)的原版英文教材很少，給雙語教學(xué)帶來了較大的困難，所以我們編寫了本書。本書為云南省普通高等學(xué)?！笆濉币?guī)劃教材，同時也是昆明理工大學(xué)省級一流本科專業(yè)過程裝備與控制工程專業(yè)建設(shè)的成果之一。本書著重介紹過程裝備研究或設(shè)計中所涉及力學(xué)方面的基本理論和基本知識，目的是使學(xué)生在提高英語應(yīng)用能力的同時為隨后的專業(yè)課程學(xué)習(xí)奠定基礎(chǔ)，在過程裝備與控制工程專業(yè)人才培養(yǎng)過程中起著較為重要的作用。本書在編寫過程中注重理論與方法的有機(jī)結(jié)合，并注意吸取國外教材一些好的編寫方法，力求通俗易懂、簡明實用。
本書由朱孝欽主持編寫。陳濤編寫第1章、第2章和第3章；朱孝欽編寫第4章、第7章和第8章；王修武編寫第5章；孫雪劍編寫第6章。全書由朱孝欽統(tǒng)稿。本書得到美國休斯敦大學(xué)Fan Wang 教授的審閱和指導(dǎo)。
本書得到云南省教育廳的資助，也感謝昆明理工大學(xué)教務(wù)處、化學(xué)工程學(xué)院的大力支持。
我們希望本書能對過程裝備與控制工程專業(yè)的雙語教學(xué)起到一定的推動作用，也希望關(guān)注、使用本書的教師和同學(xué)提出寶貴的意見。
由于編者水平有限，書中難免有些疏漏，敬請讀者批評指正。
