直流双闭环调速系统，是用神经网络作为控制器的(DC double-loop speed control systems, neural networks are used as a controller)

此方法可以实现流体力学中混沌的分叉分析，而且还可以分析皮卡尔曲面(this method can achieve hydrodynamics Chaos bifurcation analysis, but also surface can be analyzed Picard)

为我国包装动力学专业提供帮助，也为其它动力学提供方法(guide)

说明：  SAR雷达模拟的PPT，讲述SAR雷达回波模拟的具体原理，实现方法，和仿真结果(SAR)

实现一个LCC滤波 电感Lr，电感电阻R，与电感串联的电容Cr，输出并联电容Co(achieve a filter inductor Lr, inductance and resistance R, the series inductor and capacitor Cr, Parallel output capacitance Co.)

在OFDM系统 中，宽带信道被分割相互重叠的窄带子信道，如果各子信道 的带宽比信道的相干带宽要小，那么信号传输就有可能在无 频率选择性衰落或者平坦衰落的信道进行。(In OFDM system The wideband channel is divided into narrowband sub-overlapping, if each sub- The bandwidth is less than the coherence bandwidth of the channel, the signal transmission is possible without Frequency selective fading or flat fading channels.)

用于坐标转换，由xyz转换到neu方向上，基于MATLAB编程实现(Used for coordinate conversion the conversion by xyz neu direction, based on MATLAB Programming)
