刘和涛教授留美执教数十年，曾在培生教育等国际著名出版机构出版过多种教材。为美国多所院校采用。本教材秉承了国外先进教学理念，并针对国内学生实际情况，尤其注意了由浅入深的理论过渡，建立了完备的逻辑体系，语言地道，是适合于双语教学的优秀教科书，亦适合学生自学。

本书是美国培生教育出版社出版的关于微分方程定性理论方面教科书的中国版本，文中针对中国学生的具体情况做了内容调整。书中主要讲解了微分方程理论的基本方法，对微分方程的存在性、连续依赖性、稳定性、周期解、自治微分系统、动力系统等基本问题进行详细分析，并注重理论间的联系。本书基础性强、应用广泛，是一本适合大学高年级选修课、研究牛双语教学以及读者自学的英文教科书。
