Preface
Ordinary differential equation is not only a compulsory basic course for mathematics, applied mathematics, financial mathematics and so on, but also an important theoretical basis for other disciplines.The purpose of this book is to provide students with the necessary theoretical knowledge and related skills.
This book introduces some commonly used practical difference and differential models to convey to readers the importance and interest of the knowledge, together with the idea of solving practical problems.The next part is used to expand the relevant theoretical system, including the basic concepts and solving methods of difference and differential equations, and the qualitative and stability theory of ordinary differential equations.In order to give students a deeper understanding of the basic theories and knowledge they have learned, and to improve their ability to solve practical problems, we provide mathematical experiments using MATLAB in the appendix.
Our book strives to be easy to understand and detailed, and the selected examples and models are as practical as possible, paying attention not only to the students understanding of the basic concepts and methods, but also to the application of knowledge; in addition, the discussion method of this book tries to be in line with the readers thinking habits, the mathematical expression is succinct and clear, and the professional nouns are refined and explained in the form of footnotes on each page.Easy for readers to read and find.
The Chapters 1-3 of the book are written by Dr.Dongmei Zheng, the Chapters 4-5 are written by Dr.Shunjun Jiang, and the Chapters 6-7 and Appendix are written by Dr.Yanqiu Li.Dr Yanqiu Li is responsible final compilation and editing.
Because of our limited ability, mistakes and shortcomings in the book are inevitable.I sincerely hope that readers will not be stingy with their advice.

前言
常微分方程是数学、应用数学、金融数学等专业的必修基础课程,同时也是其他学科所必需的重要理论基础。编写本书的目的是希望为学生提供必备的理论知识和相关技能。
本书为读者介绍了一些常用的微分和差分实际模型,向他们传递这部分知识的重要性和趣味性,同时也为他们提供了解决实际问题的思路;接下来依次展开相关理论体系,包括差分和微分方程、微分方程组的基本概念、求解方法,常微分方程的定性及稳定性理论初步;为了让学生更深刻地体会所学的基本理论和知识,并提高学生应用差分和微分方程解决实际问题的能力,我们在附录部分提供了利用MATLAB求解的数学实验。
本书在写法上努力做到通俗易懂,详略得当,所选实例及模型尽量做到理论联系实际,既关注学生对于基本概念和基本方法的理解,也注重知识的应用;另外本书的论述方法尽量做到符合读者的思维习惯,数学表达清晰明确,并在每一页以脚注的形式对专业名词进行了提炼和解释,便于读者阅读和查找。
本书的第一、二、三章由郑冬梅博士执笔,第四、五章由江舜君博士完成,第六、七章及附录部分由李艳秋博士负责撰写,全书由李艳秋博士统稿。
本书的编写获得江苏省第二批中外合作办学高水平示范性建设工程项目培育点:南京工业大学与英国谢菲尔德大学合作举办数学与应用数学(金融数学)专业本科教育项目 苏教办外[2017]14号经费支持。
由于作者水平有限,书中不足之处在所难免,诚恳希望读者不吝赐教。
