复杂曲面

说明：  为了感谢惠俊英老师的谆谆教诲，再为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍--海洋传播声场抛物方程解算方法--RAM！ 当好奇诸君阅毕此卷，再对照轻松跑完作业，即入门 RAM！ RAM 与 AcousticsToolbox 遵照 GNU 公共许可证进行分发。感谢Michael D. Collins 对 RAM 的原创，也感谢由 Free Software 凝聚起来的自由科学家社区(In order to thank Professor Hui Junying for his teachings, and then offer you a secret book of underwater acoustic physics, ocean propagation sound field simulation, the parabolic equation solution method of ocean propagation sound field, RAM! When curious gentlemen read this volume, and then compared with easy running homework, that is, access to RAM! RAM and Acoustics Toolbox are distributed under the GNU Public License. Thanks to Michael D. Collins for his original RAM and to the Free Software community of free scientists.)

个人常用的目前比较好用的录制视频的软件工具(Personal commonly used software tools for recording video that are easy to use)

说明：  这是一个关于二维的卡尔曼滤波跟踪的代码，很简单的C语言编程，运动的是匀速运动模型。(Kalamn tracking code)

说明：  整车三自由度汽车模型，在传统二自由度操纵稳定性模型的基础上考虑了纵向力的影响，车速不再为定值。(Based on the traditional two degree of freedom handling and stability model, the three degree of freedom vehicle model considers the influence of longitudinal force, and the vehicle speed is no longer a fixed value.)

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)
