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.)

描述了形状记忆合金的超弹性，载荷为循环载荷(Describes the superelasticity of shape memory alloys)

实现10杆桁架优化，使用matlab语言结合有限元(Optimization of 10 bar truss)

该软件是针对地下导线测量的改进方法设计的，即不必在地下对全站仪进行精确的点下对中，在全站仪上安装一个偏心测量盘，通过对实际测量结果进行归化改正，从而得到理论正确的测量结果。该软件需要用户输入指定参数，如偏心距e，实际测量角度β，实际测量距离L等，从而计算出理论测量角度α和理论测量距离S(The software is designed according to the improved method of underground traverse survey, which do not have the exact point of total station in the underground, the installation of a disc eccentricity measurement by total station, based on the actual measurement results are correct so as to obtain the measurement result of domestication, correct theory. The software requires the user to input the specified parameters, such as the eccentricity e, the actual measurement angle beta, the actual measurement distance L, etc., so as to calculate the theoretical measurement angle alpha and the theoretical measurement distance S)

说明：  实现弧度向角度的转换，判断在第几象限。。。。。。(Realize the conversion of radian to angle and judge the quadrant)
