1）中英文内容相互对照，便于中外教材衔接。例如，在第2章中，中文部分中的“局部自由度”和“虚约束”分别被翻译为英文部分中的“冗余自由度”和“冗余约束”。保留这些差异是有益的。
2）在第5章中增加了平面连杆机构综合的实例，便于学生理解和掌握本章的内容。
3）用六槽轮代替四槽轮解释槽轮机构的运动特性，使主动销轮与从动槽轮的转角关系以及槽轮机构的运动系数更容易理解。
4）在第13章机械的平衡设计中增加了实例。
5）附录中包含了与课程内容相关的公式和符号的英文读法，以解决部分教师无法阅读英文公式或专业符号的问题。
6）增加了机械工程的最新进展，如柔顺机构和仿生机构。这些内容不断充实和扩展机械原理课程的内容。
7）每章增加反映基本概念、理论和方法的习题，以二维码的形式呈现。读者只需用手机微信扫描二维码即可回答问题。
8）通过二维码为书中的相应机构提供动图展示。读者只需用手机微信扫描图片旁边的二维码，即可观看动图，增强了本书的可读性。

This textbook is written for students majoring in mechanical engineering to study the course“theory of machines and mechanisms”or professional English
It is based on the basic teaching requirement of the theory of machines and mechanisms issued by the Ministry of Education， it emphasizes the cultivation of basic theories， methods， and skills， while taking design as the main line and highlighting the cultivation of innovative consciousness and innovative design abilityThe bilingual textbook not only reflects the content and characteristics of the textbooks in China， but also aligns with those abroad
Since the second publication in 2016， some schools chose this textbook as the teaching material for undergraduate courses in theory of machines and mechanismsIt was taught in Chinese， with the English content provided as a referenceOther schools used it as the English textbook for theory of machines and mechanisms courses and taught it in English， with the Chinese content provided as a referenceSome schools with bilingual teaching programs chose it as the bilingual teaching material for undergraduate courses in theory of machines and mechanismsThe teaching was conducted in both English and Chinese， with the content available for comparison and referenceSome schools selected it as the textbook for theory of machines and mechanisms courses for foreign students studying in China
The third edition incorporates much of the feedback received from faculty and students who used the first two editions and author’s selfchecks， resulting in multiple revisions， supplements， and improvements
Following are some distinctive features of this book:
1）Explanations have been provided to facilitate alignment between Chinese and foreign teaching materialsFor example， in Chapter 2， the term local degree of freedom and virtual constraint in the Chinese version are translated as redundant degree of freedom and redundant constraint in the English version， respectivelyPreserving these differences is beneficial
2）Corresponding examples have been added to Chapter 5They will be of value in the comprehensive content of planar linkages with a new method introduced
3）A sixslot Geneva wheel has been used in explaining the motion characteristics of Geneva mechanism instead of a fourslot Geneva wheel， making it is easier to understand the turning angle relationship between the driving pin wheel and driven Geneva wheel， and to comprehend the motion coefficients of Geneva mechanism
4）Examples have also been added to Chapter 13 on balance of machinery
5）English pronunciations of formulas and symbols related to the course content have been included in the appendix to address the issue of some faculty being unable to read formulas or professional symbols
6）The latest developments in mechanical engineering have been added in this revision， such as the compliant mechanisms and biomechanismsThese additions continuously enhance and develop the course content of theory of machines and mechanisms
7）Problems reflecting fundamental concepts， theories， and methods have been added to each chapter， presented in the form of QR codesReaders can simply scan the QR code use wechat app to answer the questions
8）QR code has been introduced for the corresponding animated image of the mechanismReaders can simply scan the QR code next to the illustration with their mobile phone， which enhances the readability of this book
In the end， the purpose of any textbook is to guide students through a learning experience in an effective mannerWe sincerely hope that this book will fulfill this intention
The authors of the English version are as follows：Zhang Ying of Beijing University of Technology compiled and translated Chapters 1， 2， 3， 4， 5， 6， 7， 8 and 9；Zhao Ziqiang compiled and translated Chapters 10 and 11；Zhang Ziqiang compiled and translated Chapters 12 and 13
The authors of the Chinese version are as follows：Zhang Chunlin (Chapter 1， 2 and 3); Zhao Ziqiang (Chapter 4， 5 and 6); Li Zhixiang (Cha
