说明：  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：  AB PLC以太网ControlLogixTCP，通过TCP/IP连接AB PLC。程序包包涵C#代码和VB代码(AB PLC Ethernet controllogixtcp, connect AB PLC through TCP / IP. The program includes C code and VB code)

说明：  abaqus中vumat下铝的fortran本构，二次开发，只适用于初学者，非常简单的那种(FORTRAN constitutive model, secondary development, elementary study)

C# 控制X,Y，Z 三个轴的运动，通过串口的方式通信(C# controls the movement of X, Y and Z axes and communicates through serial ports)

说明：  Matlab做有限元分析，有静态、动态、非线性分析(Matlab finite element analysis, static, dynamic, nonlinear analysis)

Abaqus 子程序，与VS，IVF联用， 用于判断模拟时工件的滑移，粘着(The Abaqus subroutine, combined with VS, IVF, is used to judge the slip and adhesion of the workpiece in the simulation.)

说明：  利用python语言实现了casa模型的NPP的计算，包括数据的读取等，亲测可用(Python implementation of the casa model)
