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.)

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.)
