简单介绍雨滴的形成，运用流体力学相关知识，分析了雨滴下落所受的黏性阻力和压差阻力，考虑雨滴在空气中下落半径增加对雨滴速度的影响，得出了雨滴下落速度和雨滴半径的关系，对雨滴下落的收尾速度进行了一般的讨论。(Brief rain formation, the use of the knowledge of fluid mechanics, analysis of viscous drag and pressure drag the raindrops whereabouts suffered consider raindrops in the air, the whereabouts of the impact of increasing the radius of raindrops speed, to draw raindrops falling speed and raindrops radius the general analysis of the relationship between the terminal velocity of raindrops whereabouts.)

利用最小二乘法辨识直流电机的参数，含有了一个simulink的直流电机模型和一个m文件，先运行模型得到数据，再利用m文件进行辨识(Least-squares method using the parameter identification of DC motor contains a simulink model and a DC motor m file, run the model to get the data, and then use the file identification m)
