通过MATLAB软件所建立的CRH2动车的模型。(Established through MATLAB software model CRH2 EMU.)

A new autonomous underwater vehicle (AUV) called H160 is described in this article. The first prototype of this AUV has been realized through collaboration between two partners, which are the Laboratory of Data processing, Robotics and Micro electronic of Montpellier (LIRMM) and the ECA‑ HYTEC (specialist in the de‑ sign and manufacture of remote controlled systems in “hostile” environments). Thispaper shows a general presentation of the vehicle, its hardware and software architecture including the process modeling and the control law used. Simulation results presented are based onthe AUV mathematical model.

灰色关联度矩阵的算法，有一定的可取性,替换数字即可，用法简单。(The algorithm of grey correlation degree has certain desirability.)

本程序是矩形波的产生。第零步定义了要产生的波形的所有特征参数，矩形波的持续时间WIDTH，矩形波的采样点数POINTS,载波频率为F0，这个频率的最终引入是便于使用RF频率发射波形。第一步包括产生矩形波，并将其调制到RF上，注意，产生的信号的持续时间是矩形波宽度的5倍，这样，总的采样点数就是5*POINTS。同时还应注意，如果要产生一个基带信号，必须设置T0=0.第二步是画出所产生矩形波的源代码。( This procedure is rectangle wave production. Step to produce stage defined the waveform of all characteristic parameters, the duration of the rectangle wave WIDTH, rectangle wave sampling POINTS POINTS, carrier frequency F0, this frequency for the ultimate introduction is easy to use RF frequency emission waveforms. The first step including generating rectangle wave, and modulated to RF, attention, produce the duration of the signal is five times the width of rectangle wave, so, overall sampling POINTS is 5* POINTS. Also, note that if you want to produce a baseband signals must set T0 = 0. The second step is to draw a rectangular wave generated by the source code. )
