The aerodynamic coefficient varies with dynamic pressures always linearly, no matter what a rigid aerodynamic force may be linear or non-linear.
不论刚体气动力为线性还是非线性，气动力系数随动压变化的趋势均呈线性。
The analysis of aerodynamic force data shows that differ front shape is very important to aerodynamic force. For example, coach model air drag coefficient can be lowed to 0.5759 from 0.7509.
试验数据分析结果表明，不同客车前部造型对气动力影响非常显著，如通过改善造型可使空气阻力系数由0.7509降为0.5759。
