说明：  Acoustics Toolbox（声学工具箱）及其中的标准算例是 Michael B. Porter 近40 年来的心血凝聚，用 Fortran、Matlab 以及 Python 等科学计算语言演绎了海洋水声传播的射线追踪、简正波和谱积分等演算方法的大量标准算例。本手册以双语版形式，可为希望深入海洋水声物理的同学和爱好者快速入门提供方便。
(Acoustics Toolbox (Acoustics Toolbox) and its standard examples are Michael B. Porter's blood condensation in the past 40 years. A large number of standard examples of ray tracing, normal wave and spectral integral of underwater acoustic propagation in ocean are deduced by using Fortran, MATLAB and Python. This Handbook is in bilingual format, which can provide convenience for students and enthusiasts who want to go deep into underwater acoustic physics.)
