These effects appear to be negligible with respect to aerodynamic coefficients. 就空气动力系数这方面来说，这些影响似乎可以略去。
The method requires using the GPS position and velocity, INS, and pitot tube so as to precisely estimate the aerodynamic coefficients by Least Square Method. 方法为采用GPS提供速度与位置，惯性感测元件提供加速度、角速度与姿态，最后以最小平方法估算各项参数值。
The aerodynamic coefficients of Case1 and Case2 , required by the workshop, are analyzed, the comparison is also made with the numerical results using CFL3D6.0 ,Cobalt60 and two sets of experimental results from AGARD. Rumsey采用CFL3D6.
It was found that it is feasible to use CFD to simulate the transient aerodynamic phenomenons and the aerodynamic coefficients of the cars change sharply like sinusoidal functions. 研究结果表明：对汽车进行瞬态空气动力学数值模拟是可行的；两车在会车前后的一段时间内气动力系数会有急剧的变化，有类似正弦函数形状的变化曲线；
The aerodynamic parameters, which are static aerodynamic coefficients of the girder and of the train and the flutter derivatives of the girder of Tianxingzhou highway-railway bridge, were obtained. 分析上、下游不同方向来流，桥上有无列车，列车不同位置和不同队列数等对桁梁和列车三分力系数的影响。
