查询词典 step down

According to the character of outer shape of modem buses, the numerical calculations are performed from the simplest shape-cuboid by using ANSYS/FLOTRAN software. First, the foreside of the cuboid is modified step by step in 17 models (this is equal to the process of modification to the foreside of a bus).

在本文中，应用ANSYS／FLOFAN软件，根据现代客车外形的特点，从最简单的长方体开始进行数值模拟计算，首先对长方体的前部进行逐步改造(相当于对一个客车头部进行改造的过程)，这一步骤包括了17个模型；然后再对其尾部进行变化，以模拟客车后车体形状对空气阻力系数的影响，该步骤包括9个模型：最后给出两种现代客车的数值模拟结果。
