本书为英文版，由我社与美国工业与应用数学协会（SIAM，Society for Industrial and Applied Mathematics）共同合作出版，在国内外同时发行。

本书力求在物理与偏微分方程之间架设一座桥梁，帮助从事应用偏微分方程学习、研究与教学的教师、研究生、高年级大学生及其他学科领域与应用部门的学者和研究工作者熟练掌握近代物理学中一些重要的基本方程，了解其来龙去脉及推导过程，理解现今国际上一些重要并常见的偏微分方程数学模型，从而可以更自觉地学习和运用，并会抓住一些有意义的问题开展研究工作。

全书分上、下两册出版。上册共5章，从最基本的物理概念出发，分别介绍了电动力学、流体力学、磁流体力学、反应流体力学、弹性力学，重点介绍建立它们的基本方程的全过程，并对这些方程在数学上的结构与特征作简略的说明，还有选择地介绍了近年来国际上的一些最近的研究成果。

The first volume of the Chinese edition of this book was published in July 1997,  and the second volume was published in June 2000. In July 2000,  upon the readers' request,  we corrected several typographical errors and republished the first volume.

In this edition,  minor typographical errors are corrected,  and a small paragraph has been added to section 5.5.4 in Chapter 5,  while the remaining text is unchanged.

We would like to take this opportunity to express our sincere thanks to our teachers，friends， and readers for their encouragement and support.
