本书第1 版出版以来，得到了许多专家、同仁及读者的关心、支持和帮助，并提出了许多宝贵意见和建议。借再版之机，首先向关心本书的广大读者、专家、同行和本书的各位责任编辑表示由衷的谢意！
在修订中，为了更适合当前双语教学的需求，我们保留了原教材的系统和编写风格（理论部分以中文为主，软件实现部分以英文为主），注意吸收当前国内外教材改革中一些成功的经验，努力体现创新教学理念，以利于激发学生自主学习，提高实践应用能力，培养综合素质和创新能力。
本次再版修订的内容主要包括以下几方面：
1．订正了语言文字表达方面的不足之处，力求用词规范，表达确切。
2．剔除了个别内容重复和烦琐之处，使理论部分更好地体现够用为度的编写原则。
3．恰当地处理有关定理的证明和有关例题的求解方法，使其更加通俗易懂。
4．增补了多重积分、有理逼近、Pad逼近等内容，进一步体现教材的先进性。
5．结合增补内容，对习题配置作了进一步充实、完善。
6．在实验部分，大量增加了算法的Matlab
实现程序及相应的算例，以便于指导学生实践应用。
本书由浙江台州学院苏岐芳副教授主编，浙江台州学院郑学良教授、李希文副教授和应玮婷老师参与修订。具体写作分工为：第1 章、第2 章及附录由李希文修订；第3章由郑学良修订；第4章~第8章由苏岐芳修订；全书的计算机实验由应玮婷修订。
在本书修订过程中，浙江师范大学徐秀斌教授为本书提出了许多宝贵意见，浙江海洋学院郝彦教授、朱玉辉老师及厦门理工学院陈淑萍老师，对本书的编写都做了大量工作，在此一并表示衷心感谢！
