说明：  为了感谢惠俊英老师的谆谆教诲，再为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍--海洋传播声场抛物方程解算方法--RAM！ 当好奇诸君阅毕此卷，再对照轻松跑完作业，即入门 RAM！ RAM 与 AcousticsToolbox 遵照 GNU 公共许可证进行分发。感谢Michael D. Collins 对 RAM 的原创，也感谢由 Free Software 凝聚起来的自由科学家社区(In order to thank Professor Hui Junying for his teachings, and then offer you a secret book of underwater acoustic physics, ocean propagation sound field simulation, the parabolic equation solution method of ocean propagation sound field, RAM! When curious gentlemen read this volume, and then compared with easy running homework, that is, access to RAM! RAM and Acoustics Toolbox are distributed under the GNU Public License. Thanks to Michael D. Collins for his original RAM and to the Free Software community of free scientists.)
