说明：  利用netcd库 python语言读取nc气象文件(Using Python language of netcd library to read NC meteorological files)

地震数据f-k滤波效果分析，地震数据处理(Seismic data F-K filtering)

宾馆管理系统论文，很全民，适合学习和借鉴(Hotel management system thesis, it is universal, suitable for study and reference)

采用相场方法，进行枝晶生长计算-标记为相场动力学模型A。(calculation of dendrite growth-model A)

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.)

房源管理系统 很好的一个参考资料 然后通过登录去管理好这些客源信息。(Housing management system, the code is the housing system of a B/S system, a good reference)

STM32F4与ADXL355通过SPI通信。(STM32F4 and ADXL355 via SPI communication.)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

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)

说明：  在abaqus平台上，采用python语言进行二次开发，对圆形骨料进行模拟。(On the abaqus platform, the python language is used for secondary development to simulate the circular aggregate.)
