卫星运动学和姿态动力学模型，采用Matlab的S-function来创建模型，可以方便更改参数(Satellite kinematics and attitude dynamics model using Matlab S-function to create the model, you can easily change the parameters)

使用ARGO数据求解经验正交函数，只给出了基本程序，无实测数据，是个小程序(ARGO data solving empirical orthogonal function, given only the basic procedures, no measured data is a small program)

电磁转矩电动机广泛应用于电液伺服阀。它们有助于扭矩转换成比例的控制电流。(The electromagnetic torque motors are widely used in electrohydraulic servovalves. They serve to convert the control current into a proportional torque. For more details about this issue, please refer to my book:)
