轮胎公式中的魔术公式89

说明：  空间计量Elhorst的所有程序，已经加载了matlab的计量程序，可以通过修改读入文件的路径一次性成功。(All the procedures of spatial mathmetrics by Elhorst, which can be successfully operated once by modifying the path of reading files.)

带有储能电池模块的光伏发电系统，储能模块稳定直流母线电压，光伏工作在mppt模式(Photovoltaic power generation system with energy storage battery module, energy storage module to stabilize the DC bus voltage, photovoltaic work in MPPT mode)

说明：  整车三自由度汽车模型，在传统二自由度操纵稳定性模型的基础上考虑了纵向力的影响，车速不再为定值。(Based on the traditional two degree of freedom handling and stability model, the three degree of freedom vehicle model considers the influence of longitudinal force, and the vehicle speed is no longer a fixed value.)

利用LABview软件的频谱分析功能实现使用FFT分析信号幅度谱和相位谱，(Analysis of Signal Amplitude Spectrum and Phase Spectrum by FFT)

说明：  PFC模型的围压伺服代码 可直接应用 为最新5.0版本代码(code of PFC the servo code to model version 5.0)

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)

GPS TOOLKIT, 非常有用的开源GPS工具包(gps toolkit, an very using and reusable opensource gps develop toolkit)

通过仿真可以进一步了解悬架性能，很具有使用意义(The performance of the suspension can be further understood through the simulation)

说明：  abaqus中vumat下铝的fortran本构，二次开发，只适用于初学者，非常简单的那种(FORTRAN constitutive model, secondary development, elementary study)

说明：  在abaqus平台上，采用python语言进行二次开发，对圆形骨料进行模拟。(On the abaqus platform, the python language is used for secondary development to simulate the circular aggregate.)
