Mechanics Fundament of Process Equipment 過程裝備力學基礎（朱孝欽）（英文版）

本書著重介紹過程裝備研究或設計中所涉及力學方面的基本理論和基本知識，全書共8 章，包括緒論、彈塑性力學概論、彈性力學的基本概念及其基本方程、彈性力學的平面問題、塑性力學基礎簡述、旋轉薄殼的基本理論、厚壁圓筒的彈塑性力學分析、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“過程裝備力學基礎”雙語課程教材，也可供相關專業(yè)的工程技術人員參考。

雙語教學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。雙語教學既可以在教授科技知識的同時幫助學生穩(wěn)步提升外語應用能力，還可以吸取國外一些好的教學方法，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，由于國外高等工科院校沒有對應的專業(yè)，因而相應的原版英文教材很少，給雙語教學帶來了較大的困難，所以我們編寫了本書。本書為云南省普通高等學校“十二五”規(guī)劃教材，同時也是昆明理工大學省級一流本科專業(yè)過程裝備與控制工程專業(yè)建設的成果之一。本書著重介紹過程裝備研究或設計中所涉及力學方面的基本理論和基本知識，目的是使學生在提高英語應用能力的同時為隨后的專業(yè)課程學習奠定基礎，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結合，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Fan Wang 教授的審閱和指導。
本書得到云南省教育廳的資助，也感謝昆明理工大學教務處、化學工程學院的大力支持。
我們希望本書能對過程裝備與控制工程專業(yè)的雙語教學起到一定的推動作用，也希望關注、使用本書的教師和同學提出寶貴的意見。
由于編者水平有限，書中難免有些疏漏，敬請讀者批評指正。
