《機(jī)械設(shè)計(jì)中的機(jī)械零件（英文版）（原書第3版）》對零件設(shè)計(jì)基本理論的敘述深入程度較為恰當(dāng)，對每章的生產(chǎn)實(shí)際背景和設(shè)計(jì)中應(yīng)考慮的主要問題作了啟發(fā)性的提示，并附有大量的例題和習(xí)題，可增加讀者的學(xué)習(xí)主動(dòng)性并便于應(yīng)用。本收兼用公制和英制，也詳細(xì)介紹了一些美國標(biāo)準(zhǔn)，這對于我國入世后了解國外機(jī)械設(shè)計(jì)的發(fā)展情況，具有一定的參考價(jià)值。

《機(jī)械設(shè)計(jì)中的機(jī)械零件（英文版）（原書第3版）》適于工科院校機(jī)械專業(yè)的教師、本科生、研究生作為教材或參考書，對于工程技術(shù)人員來說也是一本很好的參考書。
