轮胎公式中的魔术公式89

对spwm进行仿真时的参数调整以达到实现变频调速仿真目的(Parameter adjustment in SPWM simulation to achieve the purpose of variable frequency speed control simulation)

说明：  地理空间处理，功能全面。目前本软件版本较多，这是使用过的最稳定、最全面的软件(Geospatial Processing, Full Function)

说明：  在MATLAB中建立模拟地面风场的数学模型，可以用于流体计算等。(A mathematical model to simulate the ground wind field is establed in MATLAB ,and it can be used in fluid calculation and so on.)

说明：  ABAQUS子程序，计算淬火过程中的组织和温度的变化(ABAQUS subroutine is used to calculate the change of microstructure and temperature during quenching)

LMI 公司3D激光扫描仪gocator例程代码，很有参考价值，助你迅速掌握gocator的开发方法(C samples for gocator laser scanner)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

用红外控制步进电机转动角度，并且用LCD显示，采用51单片机控制，转速误差在1%之内(With infrared control stepper motor rotation angle, and with LCD display, using 51 single-chip microcomputer control, speed error is within 1%)

说明：  基于MATLAB编程实现走向无限、延伸无限的薄板状体磁异常正演(Forward modeling of magnetic anomaly of infinite and extended infinite thin plate)

pmsm转矩预测控制（还有瑕疵，请指正）(Pmsm Torque Predictive Control (with flaws, please correct))

基于MATLAB编程实现走向无限、延伸无限的薄板状体磁异常正演(Forward modeling of magnetic anomaly of infinite and extended infinite thin plate)
