波：基本原理和动力学（英文）

　　波是代表物理系统的时空行为，波特征可以构成某些动力学的基本部分。本书共四章。第一章讨论了振动和波的基本原理；第二章讨论了波的数学概念；第三章讨论了波的各种性质；第四章对与一些实战技术相联系的波的传播进行了简短的描述，但并未详细介绍这些技术。

　　吉田三一郎，Sanichiro Yoshida received his undergraduate and graduate educations in the field of Electrical Engineering and Applied Physics from Keio University， Japan. During this period， he had the opportunity to work as a student researcher at the University of Colorado Boulder. Under the supervision of Dr. Author V. Phelps，he conducted research in gaseous electronics. From this experience，he learned basics of scientific research. After receiving a PhD in 1986 from Keio University， he has conducted experimental and theoretical research on various topics， including developments and applications of lasers， optical interferometry， optical and acoustical characterization of material strength， and deformation and fracture of solids. His recent research interest is focused on development of a wave theory of deformation and fracture of solids. Currently， he is a Professor of Physics at Southeastern Louisiana University where he enjoys research with students. When not doing science， he will be found on the Judo mats or tennis courts on campus.
