为了感谢惠俊英老师的谆谆教诲，特为好奇诸君再奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，又轻松跑完9份作业（9路招式），即悟简正波海洋声场传播模型之能耐！ KRAKEN与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对KRAKEN的原创。也感谢由Free Software凝聚起来的自由科学家社区。 本秘籍适合大三以上和非水声物理专业同志们的快速参学。 吴开明 2018.12(The KRAKEN model was initially developed as a research code to evaluate new algorithms. As such it required numerous modifications to be usable as a production code. This work was begun at the Naval Ocean Systems Center and continued at the Naval Research Laboratory in support of the research on matched-field processing.)

说明：  该软件以函数化方式表示微结构换能元的边界，生成微结构换能元电热耦合仿真计算的ANSYS命令流，获得微结构换能元的电流密度、温度分布、温度梯度、电压分布等参量。该软件的技术特点在于，集成了直接耦合的微结构换能元电热耦合仿真计算方法，适用于V型边界、圆弧边界和椭圆形边界的MEMS换能元，并能进行数据及计算结果的打开、保存、输出、显示与打印。(The development purpose of the software is to express the boundary of the micro structure transducer element in a functional way, generate the ANSYS command flow of the micro structure transducer element electrothermal coupling simulation calculation, and obtain the current density, temperature distribution, temperature gradient, voltage distribution and other parameters of the micro structure transducer element. The technical feature of the software is that it integrates directly coupled thermal electric coupling simulation calculation method of micro structure transducer. It is suitable for MEMS transducer with V-shaped boundary, circular arc boundary and elliptical boundary, and can open, save, output, display and print data and calculation results.)

说明：  graph cut segmentation method.
